Title: Facsimile equipment
Inventor: YOSHIURA YOSHIO
IPC: H04N1/00
Filed: 1984-12-29
Abstract: PURPOSE:To prevent the deterioration in speed of a facsimile equipment together with miniaturization attained owing to a fact that a battery back-up memory does not need to store all picture data, by cutting off the calls after a print-out job is through with pictures. CONSTITUTION:In case a power supply 232 is cut off while a printer 228 is working, a flag showing a communication fault is set to a memory 206 for back-up. Then the power supply is cut off. When the power supply is recovered, the flag of the memory 206 is checked. If this flag is turned on, the information on the originator is read out at that time point to deliver a CR packet. Then the date information and the page information stored in the memory 206 are supplied to a picture converter 208 when the reception proceeds up to a CC packet. The picture data is produced and sent to a circuit controller 200 by a fault information signal 214. Then the picture data is transmitted through a circuit 230.

Title: Scroll compressor
Inventor: IWANAMI SHIGEKI
IPC: F01C17/06
Filed: 1984-12-26
Abstract: PURPOSE:To obtain a scroll compressor formed in a small size with a large compressing capacity, by forming a scroll tooth in both surfaces of an end plate and connecting both side spaces through communication holes while again compressing gas, compressed by the scroll tooth in one side surface, by the scroll tooth in the other side surface. CONSTITUTION:A movable scroll member 1, forming on both surfaces of its end plate a scroll tooth 1b, 1c, sets the scroll tooth 1c in one side to a number of stripes of teeth smaller than that in the other side. The scroll tooth in one side forms in its compression region a communication hole 1e, 1d, penetrating through the end plate, communicating with a suction region of the scroll tooth in the other side. Consequently, a compressor, enabling gas to be compressed in two stages by the both scroll teeth, increases a compressing capacity, but the scroll tooth 1c in one side, being positioned in an empty space in the periphery of an on-the-axis rotation preventive mechanism, serving also as a thrust bearing 16, of the movable scroll member 1 and a main bearing 14 of a driving shaft 3a, prevents the compressor from increasing its overall size.

Title: Optical scanner
Inventor: IWASAKI TAKAO
IPC: G02B26/10
Filed: 1990-10-16
Abstract: PURPOSE:To relax an allowable deviation value in the vertical direction of an optical beam by multilayering/disposing cores forming the optical waveguide of an optical waveguide array on the incident end of the optical waveguide array. CONSTITUTION:The optical beam from a light source 11 is reflected by the reflecting surface 14a of a rotary inclined mirror 14, and made incident on the incident end 15a of the optical waveguide array 15. The cores 16a forming the individual optical waveguide of the array 15 are multilayered/disposed in the vertical direction on the incident end 15a and emitting end 15b of the array 15. Therefore, even if the optical beam has a deviation in the vertical direction caused by the plane tilt of the mirror 14 and an-axis deviation, the optical beam is made incident on one of the multilayered cores 16a. Thus, the incident end of the array 15 has multilayer structure, and an incident tolerance is widened, so that the allowable deviation value in the vertical direction of the optical beam can be relaxed.

Title: Drift tube type linac
Inventor: SAWADA KENJI
IPC: H05H7/22
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To enhance the power effect of a linac, and reduce a high frequency power required for operation by making only the magnet-incorporating portion of a drift tube great in wall thickness and making a region of no magnet little in wall thickness. SOLUTION: In the cross section shape of a drift tube 20, only a four poles magnet 26 - incorporated portion is set to be thick in thickness, and a region of no magnet is set to be thin in thickness. Therefore, a capacity not contributing to the formation of an accelerating electric field becomes minimum, and the power efficiency of a drift tube type linac can be upmost enhanced. By inputting a high frequency power to the drift type linac incorporating the drift tube 20 so as to excite a predetermined resonance mode, the accelerating electric field is efficiently generated between the drift tubes 20 so that charged particles passing on a beam axis can be accelerated up to a predetermined velocity. When the shapes of both ends are formed into protruding ring-like, a more preferable electric field can be produced.

Patent JP-S61156916-A (JP)
Title: Integrated circuit
Inventor: YOSHIDA KOICHI
IPC: H03K5/00
Filed: 1984-12-27
Abstract: PURPOSE:To generate a signal used as a synchronizing signal by adopting the constitution of a push-pull buffer itself retarding a high level output and providing a circuit cancelling clock signals together after passing through a load capacitor. CONSTITUTION:Clock input signals CL1-CL4 have overlapped waveforms on each other sequentially, a transmission buffer section A uses a clock pulse from the pre-stage sequentially to inhibit the overlap for the signals and clocks CP1-CP4 are separated completely. Then clock pulses CP1'-CP4' after through a load capacitor section B are unsharpened, but since the overlapping is inhibited by the clock pulse of the next stage, the clock descends rapidly at the falling of the clock of the next stage. Thus, the sequential output clock pulses CP1'-CP4' are regarded to be separated together from the standpoint of the switching level used in the logical circuit in the integrated circuit. Thus, a signal used as a synchronizing signal is generated even in logical circuit hardware having large load capacity like a large scale integrated circuit.

Filed: 1988-11-02
Abstract: PURPOSE:To eliminate functional defects due to direct contact between a semi conductor element and a bonding wire even if the wire loop in wire bonding is made low by coating the outer surface of the semiconductor element with an insulating film. CONSTITUTION:The outer surface part of a semiconductor element 2 is coated with an insulating film 6. Therefore, when the semiconductor element 2 and an outer lead 3 are wire-bonded with a bonding wire 1, the semiconductor element 2 does not come direct contact with the bonding wire 1 even if the height of the wire loop is made low. In this way, the functional defect of the semiconductor device does not occur. Since the height of the wire loop in wire bonding can be made low, the thickness of a molding resin 5 can be made thin.
