Title: Valve seat fitting device for cylinder head
Inventor: FUJITA KAZUHISA
IPC: F01L3/22
Filed: 1979-12-22
Abstract: PURPOSE: To prevent a deformation of a valve seat by applying a filler on the external periphery of the valve seat or the inwall of a cylinder head into which the valve seat is inserted under pressure, thereby increasing fitness of the valve seat and the cylinder head.  
     CONSTITUTION: Before a valve seat 2 is inserted into a seat hole 4 in a cylinder head 1 at a cold state, a filler 6 is applied on the internal periphery and the bottom face of the seat hole 4 in the cylinder head 1. As the filler 6, a heat-resisting and effectively heat-transferring agent is used. The filler 6 flows downwards to the bottom face of the seat hole 4, because it is inclined at an angle θ. Thereby, the valve seat 2 and the cylinder head 1 contact more tightly and a higher heat transfer rate may restrict a heat-caused deformation of the valve seat 2.

Title: Gripping belt
Inventor: MATSUOKA KENJI
IPC: H04N5/225
Filed: 1991-05-30
Abstract: PURPOSE:To assure stable gripping by grabbing a body without using a long size belt and a clamping device and to reduce the weight and size of the above gripping belt by integrally forming a pressing piece having a cam surface and a rack pawl engaging with rack teeth on an operating member. CONSTITUTION:The pressing piece 6 of the operating member 4 is pushed by a finger when the gripping belt is going to be elongated or shortened. The part 7a of the rack pawl 7 is then pushed up by the cam surface 6a of the pressing piece 6 and, therefore, the rack pawl 7 is parted from the rack tooth 5. Since the sliding belt 2 is thereby freed, the sliding belt 2 slides freely if the sliding belt is pushed in this state in the elongating or shortening direction. The rack pawl 7 is engaged again with the rack tooth 5 by the recovering elasticity of 7a of the rack pawl 7 if the pressing of the pressing piece 6 is released in a required position and, therefore, the belt body and the sliding belt 2 are integrally coupled to the one piece of the nonextensible gripping belt.

Title: Image forming device
Inventor: KAJI HAJIME
IPC: G03G21/00
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To continuously execute image forming operation without stopping the image forming operation to the utmost at the time of leakage by providing a cleaning driving control part for driving a wire cleaning means in the case of temporarily stopping voltage supply by a voltage supply part. SOLUTION: Whether or not it is a state where high voltage (primary) is outputted is judged. In the case of judging that it is the outputted state, a high voltage on-signal is outputted from a CPU 201 to a high voltage unit 213 through an I/O port 206. Whether or not leakage is not caused is always monitored. When a high voltage (primary) error signal is outputted, a primary electrification protective circuit 401 acts and high voltage output is stopped regardless of the signal from the CPU. Then, an error signal 410 is outputted to the CPU 201, and the CPU 201 receiving the signal 410 sets a high voltage on-signal in an off state. The CPU 201 drives a primary electrifier cleaning motor 402 so as to clean the wire of a primary electrifier 113. After finishing the cleaning, premulti-rotating action is started and the high voltage is outputted again.

Title: Wire transmission system
Inventor: YAMAMOTO HITOSHI
IPC: H04B14/02
Filed: 1979-12-25
Abstract: PURPOSE:To permit a signal current to flow through a transmission line in one direction, by transmitting information from a terminal station to a center station by utilizing a transmitted signal from the center station. CONSTITUTION:When a signal is transmitted from a center station, a clock pulse string shown by waveform A is supplied to switching transistor T1 and from its collector, an inversion output in waveform B is outputted to terminal P1 and then transmitted to terminal P3 of a receiving terminal station via resistance (r) of a transmission line. At the receiving terminal station, the signal in waveform B transmitted is compared with a threshold level by comparator Q2 to reproduce a signal in waveform A, which is led to a receiving terminal. On the other hand, when the signal is transmitted from terminal station to the center station, switching transistor T2 is turned on-off by a code signal in waveform C that corresponds to information to be transmitted right after the reception of the pulse string in waveform B to obtain a signal in waveform D, which is sent back as information to the center station side from the terminal station.
