Title: Manufacture of crankshaft for compressor
Inventor: ISHIDOYA TADASHI
IPC: B23P13/00
Filed: 1987-10-21
Abstract: PURPOSE:To manufacture a crank pin easily without requiring eccentric machining by pressure inserting or shrinkage fitting a crank pin member into an eccentric hole made through a flange or thrust section of axle member, and making the cross-section area at fitting section smaller than those at other sections of the pin. CONSTITUTION:When a crankshaft for compressure is manufactured. a crank pin member 4 finished of final machining is pressure inserted or shrinkage fitted into an eccentric hole 3 made through the flange section 2 of an axle member 1 finished of final machining. Since the cross-section area of the crank pin member 4a is made smaller than those at other sections 4b of the pin member 4, the fitting section 4a is subjected to stress when the pin member 4 is inserted so as to prevent deformation of the pin member 4 at other sections 4b. Consequently, the pin member 4 finished of final machining can be used as it is, thus eliminating troublesome eccentric machining or rearrangement of jig.

IPC: G06F12/16
Filed: 1984-12-19
Abstract: PURPOSE:To improve a use efficiency of a ROM for parity data, to constitute with one kind of ROM and to retrieve easily a bit corresponding to address data of ROM for the data by installing a data switching circuit, etc. CONSTITUTION:A ROM8 for the parity data stores a parity bit corresponding to address data and eight bit ROM0-7 for the data. Consequently, a storing address of parity data corresponding to the data backed up is corresponding to 1:1, and respective bits of byte data in the parity data are corresponding to ROMs 0-7 to 1:1. When an address of the ROM0 is read, the bit of an address signal is wholly 0, and therefore, an input A of ROM0 and a data change-over circuit 9 is selected through a selecting circuit 10. At the ROM8, an address 0 is selected, parity data are outputted at an output, and a corresponding bit is outputted from an output PD of the circuit 9. Thus, the bit corresponding to the address data of the ROM8 can be easily retrieved.

Title: Electrochromic display
Inventor: MARUMO HIROMASA
IPC: G02F1/155
Filed: 1989-10-16
Abstract: PURPOSE:To move a discoloring part smoothly in one display body and to simplify an electric control circuit by moving a reaction area by utilizing the voltage drop of one display body. CONSTITUTION:An electrochromic display is provided with two lead terminals for applying a voltage between a display-side electrode 2 and a counter-side electrode 6 and a terminal part 11 for feeding currents to the electrodes from the two lead terminals is arranged opposite between the display-side electrode and counter-side electrode and only at a part to be changed in color. When a constant voltage is applied between the display-side electrode 2 and counter- side electrode 6, a large current flows instantaneously in the vicinity of the terminal and a voltage drop is caused at other parts not to obtain an enough voltage for reaction, but when reaction is completed at the part where the reaction starts, no current flows there, so a more current flows at a distance from the terminal pert to start reaction, whose reaction area extends outward from the starting reaction area. Consequently, a display is moved smoothly in one display body and a control circuit can be made extremely simple.

Title: Manhole for container, spherical surface in hand hole and tapered surface-like sealing structure
Inventor: ISOBE KUNIYUKI
IPC: F16J13/18
Filed: 1987-10-22
Abstract: PURPOSE:To seat a lid stably without offsetting for improving sealing ability by sphering and tapering both seat surfaces of a body and and the lid side spherical or tapered and freely fitting an O-ring to the O-ring groove formed on the seat surface in the body side. CONSTITUTION:Closing of a lid 6 brings the seat surface A in the side of the straight barrel body 4 of a container 1 into contact with the seat surface A' in the side of the lid 5. At this time, as both seat surfaces A and A' are formed into a spherical or tapered surface in correspondence with respective mates, the lid 5 seats without offsetting, Which will not give impact the O-ring 17 fitted to the O-ring groove on the seat surface A in the side of the body 4 at the specific portion. In the next step, although applying of specific pressure in the container 1 makes the lid 5 deform into such shape as bulging upward, the seal of the lid 5 can readily cope with the pressure of all areas, because there is material for sealing the wedge-like gap between both seat surfaces A and A' so as to project due to deformation. Moreover, absence of galling in the O-ring 17 serves to maintain extended durability.

Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To replace efficiently a protection circuit with a new one when it fails, by making a light emitting means emit a light through a portion of the current flowing in the protection circuit, and by grasping easily whether a current is flowing in the protection circuit or not. SOLUTION: Most of a speech current flowing from a terminal 10a into a primary protection circuit 1 is outputted from a terminal 10b through an overcurrent protection element 11a. Also, a portion of the speech current flowing from the terminal 10a into the circuit 1 is branched and outputted from the terminal 10b through a diode 14a, a current limiter element 15, an LED 16, and a diode 14c. Hereupon, since the LED 16 emits a light when the portion of the speech current flows through the LED 16, it can be sensed that the speech current is flowing in the primary protection circuit 1. In this way, by sensing the speech current, whether a subscriber is speaking or not can be grasped easily.

Abstract: PURPOSE:To prevent in advance the damage and the breakdown of mechanical parts and optical parts by detecting a variation of the incident light quantity on a photodetector by a rotation abnormality detecting part, and controlling a rotary motor in accordance with a result of detection. CONSTITUTION:When a damaged recording medium 1 is being rotated by the rated number of revolution N by a rotary motor 6, and abnormal vibration is generated in the radial direction of a rotation axis 4. As a result, a variation of the light quantity which is made incident on a photodetector 9 increases, comparing with a normal medium 1 at the time of using. Also, a frequency of the abnormal vibration of the axis 4 coincides with the number of revolution N of the motor 6, a vibration period comes to 1/N, its axis vibration detecting signal (a) becomes an output signal (b) through a BPF 12, and a rotation abnormality detecting signal (c) is detected by a fact that a level of the signal (b) exceeds a prescribed valye. Accordingly, at the time of the damaged medium 1, the motor 6 is subjected to emergency stop, and also, at the time of the normal media 1, the motor 6 is rotated continuously.
