Filed: 1988-12-09
Abstract: PURPOSE:To obtain the liquid crystal element which has a stable memory characteristic at the time of multiplex driving and has a good contrast by subjecting the silane coupling agent treated layers formed on electrodes to a rubbing treatment thereby executing a uniaxial orientation treatment. CONSTITUTION:SiO2 is deposited by evaporation as an insulating layer on the surfaces of substrates 1 which are sputtered with, for example, indium tin oxide ITO, as the transparent electrodes 2, then an amino silane soln. is applied thereon by using a spinner and is calcined. The calcined coating is subjected to the rubbing treatment. The resulted substrates are assembled via a spacer 4 to attain about 2mum cell thickness. The liquid crystal material 5 is injected between these substrates. The AC electric field of 15 Hertz and 25V is thereafter applied to this element to unify the orientation of the liquid crystal. The liquid crystal element which has the stable memory characteristic at the time of multiplex driving and has the good contrast is obtd. in this way.

Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent a long silent portion from being formed when performing a dubbing operation. SOLUTION: In the case of dubbing an audio signal recorded on a tape onto a disk, if a silent portion longer than a predetermined time Ta is detected from the audio signal obtained by reproducing the tape, a recording operation for recording on the disk the audio signal recorded in the tape is suspended for a while, and the tape is fast forwarded. In the case when no silent portion exists in the audio signal when the fast forwarding of the tape is stopped and a reproduction operation is performed, the recording operation onto the disk is resumed.

Title: Electronic equipment housing
Inventor: SHIGA MASAAKI
IPC: H01L39/00
Filed: 1987-12-09
Abstract: PURPOSE:To achieve electromagnetic wave shielding characteristics and electric conduction characteristics by a method wherein superconductive substance is contained in molding material. CONSTITUTION:The content of superconductive substance contained in molding material is preferably not higher than 60vol.%. If the content exceeds 60vol.%, the molding characteristics of a housing are deteriorated and a satisfactory molded unit can not be obtained. To the contrary, if the content is too low, the characteristics of the superconductive substance can not be exhibited. If the molded unit is applied to a word-processor, a function of electromagnetic wave shielding is given to the housing itself and an electromagnetic wave or the like emitted from a printed wiring board 2 is not transmitted outside because of the existence of the superconductive substance contained in the housing 1 and, on the other hand, an external electromagnetic wave or the like can not reach inside so that electromagnetic interference can be efficiently avoided.

Title: Cell flow rate measuring circuit for atm system
Inventor: MIYAMOTO AKIHIRO
Filed: 1992-11-20
Abstract: PURPOSE:To reduce the memory scale by storing the frequency of the same cell flow rate at each measuring time interval when the cell flow rate is measured in an ATM system. CONSTITUTION:A frequency distribution storing memory 6 inputs a cell flow rate signal S6 and stores the frequency of the same cell flow rate at each measuring time interval. A frequency latch circuit 7 latches the frequency from the memory 6 at each measuring time interval. Then a frequency adder circuit 8 increases the latches frequency. In such a constitution, the frequency of the same cell flow rate is stored in the memory 6 at each measuring time interval with the cell flow rate define as a memory address. Thus the scale of the memory 6 can be reduced.

Title: Printer
Inventor: TAMURA MASATOSHI
IPC: B41J29/46
Filed: 1990-11-16
Abstract: PURPOSE:To shorten a start-up time by allowing a control part to execute microdiagnosis only when said diagnosis is selected by a switch. CONSTITUTION:If a power supply is turned ON, CPU 1 interpretes whether a switch 4 is turned ON or OFF after initialization. If the switch is turned ON, a control part executes microdiagnosis first, and then starts routine processing. On the other hand, if the switch is turned OFF, the control part proceeds with a routine processing without microdiagnosis. Generally a printer shows a variable failure rate against an operating time. Subsequently, a printer, capable of selecting bewteen microdiagnosis and non-microdiagnosis, does not perform the microdiagnosis during a period when the failure rate is low and stable. Thus it is possible to shorten time for the start of operation without losing the reliability of hardware.

Title: Excimer light irradiating unit
Inventor: KUBODERA SHOICHI
IPC: H01J65/00
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To provide an excimer light radiating unit that is easy to design shape and area of radiating surface. SOLUTION: An electrode pair unit 10 used for the excimer light illuminating unit consists of an inner electrode 1 and an outer electrode 2 arranged concentrically. A dielectric 3 is disposed outside the inner electrode 1. A discharge space 4 is formed between the dielectric 3 and outer electrode 2. Many such small electrode pair units 10 as having a diameter of 1 to 10 mm and a length less than 5 mm or so are disposed within a container 5 filled with rare gas for producing excimer light, in such a manner that outer electrodes 2 make contact with each other depending on the desired area and shape, for instance into a honeycomb shape. This increases the area ratio of the discharge space 4 with respect to the excimer-light takeout window 7 (opening rate) and reduces irradiation mottles.  Also, small power consumption is sufficient, even if many electrode pair units 10 are used, because of small distance of discharge.
