Abstract: The present invention provides a pulse modulating method which ensures demodulation of bit data without being affected by a change in the pulse width and permits high-speed transmission, pulse modulating equipment for the pulse modulating method and pulse demodulating equipment. The pulse modulating equipment divides an input signal into n-bit words and converts it into a pulse unit signal which represents the state of the bit data for each word by time intervals i and j between odd-numbered transitions and between even-numbered transitions. The respective time intervals i and j are free from the influence of the transmission line used, for example, and remains unchanged in the pulse demodulating equipment, so that no demodulation error arises. Further, since the bit data is represented by the time intervals i and j between the odd-numbered transitions and between the even-numbered transitions, the coding efficiency increases, permitting high-speed transmission.

Abstract: A monochromator according to the present invention has an arm 1 rotatably mounted on a rotation shaft 3, and a diffraction grating 6 is fixed to the arm 1. The arm 1 is rotated by a linear motor 9 including a moving part 91 fixed to the arm 1 and a stator part 92 fixed to a base 2. The linear motor 9 is a voice-coil linear motor constructed to allow the arm 1 to rotate reciprocatively around the rotation shaft 3 within a preset angular range. The absolute rotational position of the arm 1 is detected by a rotary encoder 7 including a crossbar 71 fixed to the arm 1 and a encoder block 72 fixed to the base 2. Based on the output signal of the rotary encoder 7, the linear motor 9 is controlled so that the moving part 92 rotates at a fixed angular speed around the rotation axis 3. Thus, the wavelength scanning is carried out at high speed, and sampling of monochromatic light having desired wavelengths is performed accurately.

Abstract: The present invention provides a pointing device which can be mounted in a limited space in a PC housing with no gap therebetween and which permits continued control of a cursor on the PC screen regardless of the size of a tablet sheet. Cursor control data is produced from data about the positional relationship between a pressed position (x.sub.n, y.sub.n) on the tablet sheet and a fixed reference position (x.sub.0, y.sub.0). Since the relative position data represents the distance and direction of the pressed position relative to the reference position, the movement of the cursor can be controlled by changing only the position where to press the tablet sheet relative to the reference position when the cursor control data is provided to a personal computer. Hence, even if the tablet sheet is narrow, the cursor can be controlled continuously. Additionally, marginal portions of the tablet sheet can be closely joined to the PC housing with no gap therebetween.

Abstract: When a pair of opposed resistance sheets of a pressure sensitive 3D tablet are pressed into contact with each other by a tablet manipulation, an equal current is applied to a reference resistor R.sub.C, and the position of contact (x.sub.p,y.sub.p) between both sheets and a first potential difference V.sub.A, based on the resistance value r.sub.C of the reference resistor R.sub.C and a second potential difference based on the contact resistance r.sub.p at the contact position, are detected. Since the contact resistance r.sub.p can be detected by r.sub.P =r.sub.C *V.sub.B /V.sub.A, the X- and Y-coordinates (x.sub.p) and (y.sub.p) and the contact resistance r.sub.p at the position of contact between the resistance sheets can be detected as 3D independent parameters.

Abstract: The present invention concerns a relative manipulated variable input device which is capable of controlling the cursor movement in correspondence to the direction and amount of tilt of a control button and controlling the speed of the cursor movement in accordance with the force applied to the control button as well. Output data is generated using relative position data calculated from the difference between a pressed position and a reference position and a contact resistance value r.sub.p. The output data, which represents the direction and amount of tilt of the control button, is output in accordance with the force applied to the control button. The relative position data represents the direction and amount of tilt of the control button and the output data is produced based on the relative data. Hence, the cursor movement can be controlled by the direction and amount of tilt of the control button, and by changing the force exerted on the control button to change the contact resistance value r.sub.

Abstract: A pressure sensitive resistance tablet coordinate input device is provided which enables the cursor to be moved to a desired position on a PC display by pressing a tablet sheet (6) with a stylus, permits the stylus press-shift operation at the center of the tablet sheet (6) and maintains the continuity of control of the cursor movement even if the pressure to the tablet is once removed. The device is selectively switchable between an absolute value output data in which pressed-position data (x.sub.n,y.sub.n) is used as cursor control data (X.sub.n,Y.sub.n) or a relative value output mode in which relative position data is calculated by comparing pieces of pressed-position data before and after the stylus press-shift operation on the tablet sheet (6). The relative position data thus calculated is used as the cursor control data (X.sub.n,Y.sub.n). Since either one of the two modes of operation can be selected in accordance with the contact resistance value r.sub.

Abstract: The invention concerns a tablet pointer that enables the drag mode to be retained even when the operation surface of a tablet sheet is so narrow that the stylus press-held thereto needs to be temporarily lifted off. Switch data generating member provided in the tablet pointer produces switch data indicating the operating state of a mouse switch and device output data of the tablet pointer is fed to a personal computer as an output of an operation unique to the mouse, such as drag mode data. While in a keep-drag mode, the switch data generating member does not cancel the drag mode even if it is supplied with an ordinary drag cancel input. Hence, the drag mode can be retained even if it receives a drag mode cancel signal during the drag operation.

Abstract: A digitizing tablet includes stacked X and Y coordinate resistance boards (X-board and Y-board) with insulating beads therebetween. A CPU controls input and grounding switches of both X- and Y-boards and a selector switch. The selector switch connects an A/D converter input to grounding electrodes of the X and Y boards. The input switch of the X-board applies a supply potential to an input electrode of the X-board while a grounding electrode of the X-board is disconnected from ground by the grounding switch. The Y-board is grounded at a grounding electrode while the input electrode of the Y-board floats. The A/D converter monitors a voltage at the grounding electrode of the X-board to detect a drop in potential from the supply potential. When contact pressure is applied to the digitizing tablet, current flows from the supply potential, through the X and Y boards via a contact point, and into ground via the Y-board grounding switch.

Abstract: A spinning reel has a detachable cover for closing a side of a reel body. The reel body includes engaging pieces, while the cover includes engageable elements.The cover is movable between a first position for tight contact with the reel body to close an interior of the reel body, and a second position rotated a predetermined angle from the first position about a lateral axis of the reel body. The engaging pieces are engaged with the engageable elements when the cover is in the first position, to realize the cramping of the cover with the reel body, to assure the closed condition of the reel body, and disengaged from the engageable elements when the cover is in said second position, to allow the cover to separate from the reel body. And the reel have a locking system to maintain the cover in the first position.

Abstract: A data input resistance pad for measuring coordinates and pressure of a stylus pressed on the pad has X and Y-coordinate resistance boards. The X and Y-coordinate resistance boards are connectable by respective switches to high and low voltage sources at opposite ends of each board. By measuring the voltage at either side of a contact resistance with a high impedance voltage measuring device, a voltage drop across the contact resistance is calculated. This voltage drop represents the contact resistance and therefore the pressure of the stylus. The X position is calculated by measuring the voltage drop from an end of the X-coordinate resistance board to the point of contact. The Y position is calculated by measuring the voltage drop from an end of the Y-coordinate resistance board to the point of contact.

Abstract: A spinning reel includes a spool mounted on a spool shaft. An engaging mechanism is disposed in a rear end region of the spool for interconnecting the spool and spool shaft to allow torque transmission therebetween, and limiting rearward movement of the spool. A stopper is disposed in a front end region of the spool for limiting forward movement of the spool. The engaging mechanism includes an engaging piece formed on the spool shaft, and an engaging portion for contacting the engaging piece to prevent the spool from rotating relative to the spool shaft. An elastic retainer is provided for preventing relative rotation or relative axial movement between the spool and spool shaft when the engaging mechanism is in operation.

Abstract: A coordinate detection device has upper and lower resistive plates. Pressure on the upper resistive plate causes the two plates to come into electrical contact at a point of the pressure allowing an external device to compute the coordinates of the applied pressure. Each resistive plate has a layer of transparent resistor material over a transparent substrate. Two parallel electrodes of silver are spaced apart on each resistive plate to create a linear potential gradient therebetween. The electrodes are connected across a voltage potential via lead wires which are made from the same material as the transparent resistor.
