Filed: 1994-09-12
Abstract: PURPOSE: To provide a wiper with a lip, in which the follow-up speed of the lip part corresponding to the change of a gap between a cover and the lip part is high, and a change in sliding resistance is small, and which has a long life. CONSTITUTION: A wiper 10 formed by sticking a thin spring steel plate 10B to the forward end part of a wiper main body 10A made by a rubber material in such a manner as to be projected is installed on the end face of the sleeve part 9a of a fixed cover. Even in the case where a wavy moving cover 8 is moved by the wiper 10, the displacement of the forward end lip part 10a is large, and the lip part is displaced in short-periodically, the lip part is always kept from separating from the opposite surface by the quick response repulsion of the thin spring steel plate, and a good wiper effect can be maintained.  There is little change in sliding resistance which has a bad effect on the moving positioning accuracy by the rubber material and a low serial spring constant of the spring steel plate, and further as the rubber material is protected from high temperature chips by the thin spring steel plate so as to decrease deterioration.

Title: Complementary mos output buffer circuit
Inventor: ASAGI TOMOFUMI
IPC: H03K17/687
Filed: 1988-09-28
Abstract: PURPOSE:To reduce the current driving capability and to decrease the through- current by providing a P-channel MOS TR, two N-channel MOS TRs, two made registers corresponding to the N-channel MOS TRs and two AD circuits. CONSTITUTION:Control signals I2, I3 inputted to input terminals 12, 13 are written in registers R1, R2 when a mode register write signal I4 inputted to an input terminal 14 is at an H. While the signal I4 is at an L, the registers R1, R2 latch the written control signals I2, I3 respectively. Thus, the registers R1, R2 select the state of 3 kinds of buffers as shown in table depending on the combination of H, L of the control signals I2, I3 written in the mode registers R1, R2 when the write signal I4 is at an H level. Thus, the current driving capability of the output buffer circuit is varied and the current driving capability is reduced to reduce the through-current.

Abstract: PURPOSE:To perform completely optical arithmetic processing and to easily miniaturize and integrate an optical full adder by constituting the optical full adder of a branch circuit where optical joining device and an optical branching device are connected in parallel and using an negative optical stable element and a positive optical stable element in the branching circuit. CONSTITUTION:Optical amplitude values of an optical augend input signal Pa, an optical addend input signal Pb, and an optical carry input signal Pc are set to 21 when logical values are '1', and they are set to 0 when logical values are '0'. Thus, an optical joined signal Pabc outputted at the time of input of an optical input to an optical joining device 4 is equally divided into two by an optical branching device 6 and is properly outputted as branched optical signals Pw to excite branching circuits 7 and 8. Optical amplitude value '1' is determined as respective thresholds of a negative optical stable element 9 and a positive optical stable element 10. That is, in the case of the element 8, an output Pout takes a high value PH when the optical amplitude value of an optical input Pin is '1', and it takes a low value PL when the optical amplitude value is 21, and it takes the high value PH again when the optical amplitude value is 31.

Filed: 1994-10-11
Abstract: PURPOSE: To make it possible to execute the search for a fault point readily by arranging a dielectric multilayered-film filter at the specified position of the intersections of all split paths of a light splitting/coupling device or all optical fiber lines. CONSTITUTION: The wavelength region of passable inspecting light is limited in correspondence with the film thickness of a dielectric multilayered-film filter, which is inserted into an optical splitting/coupling device 15, in the light propagating direction at each split light port. At each split light port, several kinds of cutoff wavelengths are determined. Therefore, when a plurality of optical lines 16 are monitored based on the inspecting light emitted from a variable wavelength light source 11, each reflected light is received with a photodetector 13 for every wavelength, which is marked off with N kinds of cutoff wavelengths.  Therefore, when the linear-shape operation is performed for the reflection loss of each wavelength with an operation/control circuit part 14 based on the intensity level of the reflected light corresponding to the respective wavelength, the fault point in each split light port and the line 16, which is optically connected 5, to the port, can be independently detected based on the difference of the reflected lights between the respective split light ports.
