Title: Method for driving liquid crystal cell array
Inventor: OBA YUJI
IPC: G09G3/36
Filed: 1988-10-31
Abstract: PURPOSE:To eliminate the period for a compensating signal so as to improve the recording speed by providing a light transmitting section and light non-transmitting section in each cell by using one wire and two common electrode per one picture element. CONSTITUTION:The liquid crystal cell array is provided with a basic cell 1, a pair of transparent plates (upper and lower) 2 and 3, spacer 4 between the upper and lower plates 2 and 3, transmissive hole 5 in the spacer 4, electrode 6 of the upper plate 2, electrodes 7 and 8 on both sides of the lower plate 3, and transparent main electrodes 9 and 10 respectively formed at the upper and lower plates 2 and 3. At the time of setting part of or all of this liquid crystal array to a stopped state, a signal voltage produced by superimposing high frequencies of different voltages upon a one-polarity low-frequency voltage is applied across the two electrodes of one plate and a driving waveform is used for the transparent electrode of the other plate for applying a one-polarity low-frequency voltage. Or, a signal voltage produced by superimposing a one-polarity high-frequency voltage upon different low-frequency voltages is applied across the two electrodes of one plate and a one-polarity high frequencies are impressed upon the transparent electrode of the other plate. Therefore, the period for a compensating signal can be eliminated and the recording speed can be improved.

Title: Digital speed recorder
Inventor: MURAKAMI KENJI
IPC: G01P1/12
Filed: 1987-10-31
Abstract: PURPOSE:To instantaneously read information on the traveling state of an automobile in a desired time zone by storing a sampled value of the speed of the automobile and storing specific time in a storage part right after the sampled value. CONSTITUTION:When an IC card 7 is inserted, the speed detection part 2 of the automobile supplies a detected value to an interface circuit 3. A microcomputer 4 processes the sampled value which is read in from the circuit at a desired sampling period according to a program stored in a ROM 6. This processed sampled value is stored in a RAM 5 temporarily. A time signal from a clock IC 8 is read in after the sampling and when this time signal is unit time, the time is stored 7 right after the sampled time. Further, when not, a next sampled value is read in and stored 7. Therefore, the card 7 is stored with a marker and time together with the information on the traveling state and when the traveling state is analyzed, the traveling state in a desired time zone is read as necessary.

Title: Fluid damper
Inventor: TERAMURA AKIRA
IPC: F16F9/16
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To reduce size, weight and a manufacturing cost of a damper itself by sufficiently elongating a communication passage in respect to a sectional area thereof, and increasing flowing resistance of an operation fluid due to the length of the communication passage. SOLUTION: Pressure difference p1-p2 is generated between two cylinder chambers 16 and 18 by means of a tube 26 which is externally attached so as to bridge both ends of a cylinder 12. At this time, oil is flowed through the tube 26 so as to eliminate the pressure difference. Viscous resistance is generated in the tube 26 to attain damping force. The tube 26 has sufficient length such that communication length is sufficiently longer than the communication diameter. Viscous resistance of an operation fluid flowed through the communication passage can be set sufficiently high. A sectional area of the communication passage can also be set large since the flow passage is long. Viscous resistance is also increased by increase of kinetic energy. It is thus possible to reduce size, weight, a manufacturing cost of a fluid damper while keeping large capacity of the fluid damper.
