  • Patent number: 5476427
    Abstract: When a lap switch is operated, data of a lap time stored in a register T is stored in a lap register pointed out by a pointer PR. An average pace for a section of a course is calculated on the basis of data of a step count for that section stored in a register H and data on the lap time for that section stored in the register T. Data on a calculated average pace is stored in a lap register. A pace difference between the present and the immediately preceding average pace is calculated and data on the pace difference is stored in an appropriate lap register. Thereafter, the pointer PR is incremented by one.

  • Patent number: 5477349
    Abstract: A liquid crystal injecting method, wherein the area of a portion of a liquid crystal cell, which is dipped in a liquid crystal contained in a liquid crystal vessel, is reduced to a minimum, thereby preventing the liquid crystal in the vessel from being contaminated with foreign matter and reducing the amount of the liquid crystal which unnecessarily adheres to the outer surface of the cell. The liquid level of the liquid crystal in the vessel is detected by a sensor. Liquid crystal is supplied to the vessel on the basis of the detected liquid level to maintain the liquid level at a predetermined height. A portion of the liquid crystal is raised. A liquid crystal injecting port of the cell is dipped into the raised portion of the liquid crystal after an inner space of the cell is evacuated. Thus, the liquid crystal is injected into the cell.

  • Patent number: 5474077
    Abstract: An exercise-level of difficulty data output apparatus outputs exercise-level of difficulty of an exercise which a user takes, as exercise-level of difficulty data, which can be used for general purposes in the exercise physiology. Using the apparatus, the user can objectively learn the exercise level of difficulty of his (or her) exercise for keeping himself healthy or for developing his physical strength. The exercise-level of difficulty data output apparatus calculates exercise-level of difficulty data from counted pulse number of the user and his age, and outputs the exercise-level of difficulty data. Further, the exercise-level of difficulty data output apparatus calculates and displays a predetermined pulse-number range indicating the most suitable exercise level of difficulty for the age of the user.

  • Patent number: 5471438
    Abstract: A wrist watch (1) is provided with a cover member (3) attached to a wrist watch case (2) by a coupling portion (3) in a openable/closable manner. A liquid crystal display device (4) to display time is incorporated in the cover member (3). A retaining section (7) for retaining a disk-like data memory is provided on the upper surface of the wrist watch case (2). The data memory in the .retaining section (7) is securely held with the cover member (3) closed. Data in the disk memory (9) is read and processed by the electronic circuitry (2b) of a watch, and is sent to the liquid crystal display device (4) via a flexible circuit board (2e). The data is then converted into a time which is in turn displayed. The data memory can therefore be very easily attached or detached, and is securely held. The wrist watch itself can be made compact. Replacing the data memory with another one can provide advantages such as displaying various types of data.

  • Patent number: 5467440
    Abstract: A data edit unit creates an employee master file and a position table file. An intra-block arrangement definition table is created via a data input unit. An intermediate table creation unit creates an intermediate table by looking up the employee master file and a position table in the position table file, and stores the intermediate table in an intermediate table file. A hierarchical block development unit creates print image data of an organization chart in which print image data of respective blocks are arranged at corresponding hierarchical positions, in a hierarchical image memory by looking up the intermediate table and the intra-block arrangement definition table. A print image development unit connects the blocks by ruled lines in accordance with the hierarchy connection relationship by looking up the intermediate table, thus completing print image data of an organization chart. The organization chart is printed out via a print unit.

  • Patent number: 5465102
    Abstract: An image display circuit supplies gray scale data according to a video signal to a liquid crystal panel to present a gray-scaled display, and scans the liquid crystal panel N times during one field period of a video signal. The image display circuit includes a table ROM comparing a current video signal with a previous video signal of one frame before, and generates gray scale data for N times in accordance with the comparison result. Gray scale data greater than the gray scale of the current video signal is generated when the comparison result indicates that the gray scale of the current video signal is greater than that of the previous video signal, and gray scale data smaller than the gray scale of the current video signal is generated when the gray scale of the current video signal is found to be smaller than that of the previous video signal. Based on the generated gray scale data, the liquid crystal panel is driven with the proper gray scales.

  • Patent number: 5463420
    Abstract: A photosensor formed on an insulating substrate has a transparent top gate electrode arranged on the upper side of a semiconductor layer for photoelectric conversion and a bottom gate electrode arranged on the lower side of the semiconductor layer. If light is applied from the top gate electrode side in a state in which a bottom gate voltage V.sub.BG =+20 V is applied to the bottom gate electrode and a top gate voltage V.sub.TG =-20 V is applied to the top gate electrode, electron-hole pairs are generated in the semiconductor layer and only the holes are held in the semiconductor layer by the effect of the top gate voltage V.sub.TG =-20 V. Therefore, an n-channel is formed in the semiconductor layer and a drain current I.sub.DS flows. It was confirmed that the drain current I.sub.DS will not flow even if illumination light is applied when the bottom gate voltage V.sub.BG is set at 0 V. Therefore, the selection or non-selection state of the photosensor can be controlled by the bottom gate voltage V.sub.TG.

  • Patent number: 5461419
    Abstract: A plurality of photosensors are formed on an insulation substrate in a matrix fashion. Each of the photosensors includes a photoelectric conversion semiconductor, first and second gate electrodes, a drain electrode and a source electrode. A signal line is connected to each drain electrode. After precharge signals are applied to the respective signal lines by driving a switching circuit, a sense voltage is applied to the first gate electrode, a selection voltage is applied to the second gate electrode, while a light beam is supplied to the photoelectric conversion semiconductor. As a result, the precharge voltages held on the signal lines are lowered by voltages corresponding to the intensity of the incident light beam.
