Abstract: PURPOSE:To obtain an image pickup device with an electronic shutter and an electronic diaphragm function free from color mixture, a after image and sticking by controlling DC voltage to be impressed to a photoconductive film within a range where the photoconductive film acts a current amplifying function. CONSTITUTION:A target power circuit 4 impresses target voltage upon a first electrode formed on the upper surface of the photoconductive film 2 as conforming to a designated diaphragm value, and controls the voltage level or the impressing time of impressed voltage within the range where the photoconductive film 2 acts the current amplifying function. Accordingly, such a phenomenon that a sufficient electric field is generated in the photoconductive film 2 and a part of generated electric charge is diffused in a lateral direction in to the film 2 or is trapped at a boundary surface part between the film 23 and the electric field never occurs. Thus, in the electric diaphragm or the electric shutter, the deterioration of picture quality due to the color mixture, the after image and the sticking, etc., can be prevented.

Title: Method and device for reducing noise of picture signal
Inventor: OYAMA KOICHI
IPC: G09G5/00
Filed: 1991-01-09
Abstract: PURPOSE:To greatly improve a noise removing efficiency with a small distortion by removing the noise by changing a multiplying coefficient by utilizing the difference in visual senses in the levels of the brightness of a picture against the distortion. CONSTITUTION:When an input picture signal 71 is impressed, the level of the brightness and the polarity of the input picture signal 71 are judged by a judgement section 51. When a visual sense to the distortion called as commet tail is low, a noise reducing efficiency is enhanced by utilizing a coefficient K whose value is smaller than 1. On the contrary, when the visual sense to the distortion is high, the occurrence of the distortion is reduced in an area where the visual sense to the distortion is high by utilizing the coefficient K whose value is closed to 1.

Title: Power converter
Inventor: YASUOKA IKUO
IPC: H02M7/515
Filed: 1981-01-30
Abstract: PURPOSE:To prevent the destroy of a GTO by stopping the supply of a gate control signal at the time of an overcurrent defect and breaking a high speed breaker. CONSTITUTION:When a load current exceeds a set protecting value, a level comparator 8 detects it, and the output of the comparator 8 becomes ''L'' level signal from ''H'' level signal. When the output gate control signal of a gate control signal generator 9 is blocked by AND circuits 10, 11, the trip coil 4a of a high speed breaker 4 is energized simultaneously. However, a GTO 5 continues to conduct even if it blocks the ON gate signal, and the load current further increases, but since the breaker 4 is tripped after the prescribed time, the current is thereafter attenuated. Even if the load current exceeds the peak turn-off current at this time, no OFF gate signal is applied to the GTO 5. Accordingly, the GTO is not destroyed.

Title: Loop type network equipment
Inventor: INAO KIYOHARU
Filed: 1986-01-23
Abstract: PURPOSE:To effectively conduct the test of a MODEM equipment and a communication line used by each communication equipment by selecting a cyclic packet returned while being circulated on a loop type communication line so as to return it to an interface INF and using it as a local loopback test. CONSTITUTION:When a loop communication control circuit CNT receives a packet RXPACKET, a discrimination means 11 decides whether the received packet is a packet sent from other communication equipment or a cyclic packet circulated while being sent from the own station. When it is decided that the packet is sent from other communication equipment, an H level control signal RXDET is outputted to a selection circuit SEL. On the other hand, when a cyclic packet RT PACKET is received, an H level control signal RTDET is outputted to the selection circuit SEL. In such case, the selection circuit SEL brings the packet reception detection signal PDET to the H level. The interface INF receives it to receive the cyclic packet from a loop communication control circuit CN and uses it as a local loopback test.

Title: Spin coating method for surface of synthetic resin substrate
Inventor: SHIMIZU YOSHIO
IPC: G11B7/26
Filed: 1994-02-07
Abstract: PURPOSE:To prevent a coating agent from overrunning to the back side of a substrate by keeping specified distance between the tip of a coating agent supply nozzle and the surface of a synthetic resin substrate. CONSTITUTION:A synthetic resin substrate, with its coating surface kept horizontally, is rotated at a low speed. The substrate, after being coated with a cure type coating agent, is then rotated at a high speed to get rid of the excessive coating agent, and the coating agent is cured. In this process, the viscosity of the coating agent is 30-200cps, and the distance between the tip of a coating agent supply nozzle and the surface of the synthetic resin substrate is 0.3-2mm. When the viscosity deviates from the range, a coating film with uniform thickness can hardly be obtained. If the distance exceeds 2mm, the coating agent discharged from the nozzle is repelled on the surface to form droplets, causing the undesirable overrunning of the coating agent onto the back of the substrate.

Title: Micro-vibration suppressing device
Inventor: OTANI AKIHITO
IPC: F16F13/08
Filed: 1994-02-07
Abstract: PURPOSE:To effectively suppress the generation of micro-vibration by providing a first container which is connected to an object to be vibrated and caused to change an amount of stored fluid through expansion and contraction, a second container which is connected in parallel thereto and is caused to absorb the fluctuation of internal fluid, and a control means which is located between the two containers and exerts insertion resistance on internal fluid. CONSTITUTION:When an object B to be vibrated is moved toward a support structure C, since a device A is compressed on the whole and the volume of a first container 1 is reduced, internal fluid R flows through the orifice 33 of a control means 3 to a second container 2. When the pressure of the internal fluid R is increased since the internal fluid R is noncompressible, internal gas of a gas chamber 4 is compressed, and the size of the second container 2 is allowed. When the object B to be vibrated is separated away from a support structure C, a device is stretched on the whole, the volume of the first container 1 is increased, the internal fluid R of the second container 2 flows in the first container 1, the pressure of internal gas of a gas chamber 4 is decreased, and the increase of the size of the second container 2 is allowed. Thus, suppression of the generation of micro-vibration is practicable.
