Abstract: An on-car motor driving apparatus is equipped with a motor for moving a moving unit such as a window of a motor car, a motor driving controller which controls the revolution, stop, and rotational direction of the motor, and a current measuring and comparing device which measures the variation in current per unit time of the motor and compares the measured variation in current with a preset value. The on-car motor driving apparatus stops the revolution of the motor and/or reverses the rotational direction of the motor through the motor driving controller. The apparatus is further equipped with a voltage measuring device for measuring motor driving voltage and a voltage-based time setting device which changes the length of the unit time in accordance with the driving voltage value measured by the voltage measuring device. Line voltage is supplied to a differential amplifier only when the line voltage is supplied to the motor.

Abstract: An optical reading system including a warning sound for preventing theft of a portable optical reading apparatus (scanner). A timer is activated when movement of the scanner is detected by a movement detection device mounted on the scanner, indicating that the scanner has been lifted (moved) from a stationary condition. A user determination unit determines whether the movement of the scanner is caused by an authorized user. When the user is an authorized person, a timer is reset. When the timer is not reset during a predetermined time period, a warning sound is generated at a sound level which changes from a low sound level to a loud sound level over a period of time unless a predetermined operation is performed. In one embodiment, a second warning sound is generated at a stationary receiving station when the scanner does not respond to a polling signal.

Abstract: A vibratory gyroscope including an elongated vibrator having a central (neutral) axis (Y-axis), a drive unit for deforming the first direction such that the vibrator vibrates in a first (X) direction, an added mass attached to the vibrator at a position offset from the central axis in a second (Z) direction, and a detector formed on the vibrator. Rotation of the vibratory gyroscope about the second (Z) direction during vibration in the second direction causes Coriolis force to acting on the added mass in a direction parallel to the central axis. Because the added mass is offset from the central axis, a resulting vibration in the second (Z) direction is produced, which is detected by the detector. With this arrangement, the central axis of the vibrator is placed in parallel with the surface of rotation of the rotating system. Thus, rotations about two or three axes in each direction can be detected in such a manner that noise generation is prevented.

Abstract: A balanced-to-unbalanced converting circuit in which balanced-to-unbalanced converters are formed by a stripline in such a manner as to include a copper foil pattern which is formed on an inner or surface printed circuit layer of a multi-layer substrate and are connected to a double balanced mixer serving as a surface-mounted component provided on a first printed circuit. In the case of this converting circuit, a part of conventional surface-mounted components are eliminated from the multi-layer substrate. Thereby, the high density packaging of other surface-mounted components can be achieved. This contributes to the miniaturization, thickness reduction, weight reduction and price reduction of an entire portable telephone. Further, the balanced-to-unbalanced converters are formed by placing the copper foil pattern on a printed circuit layer which is sandwiched between grounded conductor layers of the multi-layer substrate.

Abstract: Disclosed is a safety device of a secondary cell, which comprises a lid having an opening section and directly or indirectly fixed for closing a cell case; a pressure receiving means covering the opening section and having flexibility to displace with an internal pressure of the cell; an element having a conductive path connected at one end to an internal electrode of the cell and at the other end to an external electrode, for breaking the conductive path with displacement of the pressure receiving means resulting from a change in the internal pressure of the cell; and locking pawls which fasten the pressure receiving means to the lid by staking to close the cell interior, to thereby keep the cell interior closed when the internal pressure is at a specific value or less and to release a gas from inside through a gap produced between the pressure receiving means and the lid by unfastening staked sections when the internal pressure has exceeded the specific value.

Abstract: An E-shaped core is composed of a main core and side cores which are combined into one piece. A coil is wound around a bobbin which is inserted in the main core. A plate-shaped auxiliary core is connected to a sliding member. Connecting the E-shaped core and the auxiliary core completes the assembly of the magnetic head for a magneto-optical recording device. The auxiliary core surrounds the main core; therefore, the concentration of the magnetic flux at the end of the main core can be enhanced and the efficiency for generating magnetic field for a recording medium can be improved. In addition, the use of the E-shaped core and the plate-shaped auxiliary core permits easier machining of the cores.

Abstract: An IBM PC compatible keyboard is provided which, on power-up, does not access the keyboard LEDs until receiving a command from the host computer. When the keyboard controller performs a Basic Assurance Test (BAT) on power-up before receiving a host command, the controller does not turn on the LEDs. Upon receiving a Reset command from the host, the controller: (1) turns on the LEDs and performs a BAT with LEDs on; and (2) flashes the LEDs a second time to be compatible with the IBM PCs. Another feature of the invention is a non-destructive test of the controller RAM during BATs. The RAM is tested non-destructively both for the "stuck-at-1" and the "stuck-at-0" conditions. Still another feature is that the controller determines the state of the keyboard LEDs without reading a hardware port. The controller keeps track of the LED state by flags in the controller memory, and the controller determines the LED state by reading the flags.

Each of the operation plates has an opening formed therein for passing light emitted from an LED therethrough and has a pair of projections formed thereon next to the opening.

Abstract: In a magnetoresistive magnetic head having a laminate composed of a magnetoresistive (MR) layer showing the magnetoresistive effect, a SHUNT layer as a non-magnetic layer and a soft adjacent layer (SAL) for applying a transverse bias magnetic field to the MR layer, the MR layer and the SAL are made of the same Ni.sub.81 Fe.sub.19 magnetic film. Since the SAL is magnetically saturated in the same direction as the direction of leakage flux of a recording medium (y direction), permeability thereof in the y direction decreases, and the MR effect function therein can be restricted. Although the MR layer and the SAL have the same specific resistance .rho., a sufficient detection current can be made to flow through the MR layer and a high-precision magnetic detection output can be obtained by making the MR layer thicker than the SAL.

Abstract: A thermal printer that performs thermal printing by employing a commonly-used thermo-sensitive recording sheet. In the thermal printing, a thermal head starts heating the recording sheet from the back side of a base that covers a recording surface in order to print, so that the recorded information is effectively hidden from view. When the thermal printer performs thermal printing by using a two layer thermo-sensitive recording sheet, high quality images with sharp edges can be reliably recorded. The thermal printer uses two types of thermo-sensitive sheets to perform thermal recording.

Abstract: As an antiferromagnetic layer achieving exchange anisotropic coupling with a ferromagnetic layer, any Mn alloy of Ru-Mn, Rh-Mn, Ir-Mn, Pd-Mn, and Pt-Mn alloys is used. The content of each element is 10 to 45 atomic % for Ru, 10 to 40 atomic % for Rh, 10 to 40 atomic % for Ir, 10 to 25 atomic % for Pd, and 10 to 25 atomic % for Pt, respectively. Since the alloy exhibits excellent corrosion resistance and exchange anisotropic magnetic field in spite of its irregular crystal structure, no high temperature treatment is required in order to achieve a change in the crystal structure. The alloy is durable to high temperature due to a decreased change in the exchange anisotropic magnetic field.
