Title: Device for erasing electric charge of photosensitive drum
Inventor: IRIE YOICHIRO
IPC: G03G21/00
Filed: 1985-05-16
Abstract: PURPOSE:To make it possible to erase electric charge precisely even if light sources having the small quantity of light are used by arranging plural destaticizing units on the periphery of a photosensitive drum and controlling the flashing of the light sources in accordance with the rotational speed and the interval between respective units. CONSTITUTION:The 1st-3rd destaticizing units 31-33 are arranged on the periphery of the photosensitive drum 11 and many light emitting diodes 35 are arranged in respective frame bodies 34. The flashing of the diodes 35 is controlled in accordance with the rotational speed of the drum 11 and the distance L between respective destaticizing units and these light emitting diodes 35 are constituted so as to irradiate the same point on the drum 11 through delay circuits 39. Since the irradiating range can be precisely made to coincide with the same point on the drum 11, the electric charge of a non-picture part can be precisely erased even if the light emitting diodes 35 having only the small quantity of light are used as the light sources.

IPC: G01C22/00
Filed: 1991-05-09
Abstract: PURPOSE:To eliminate a measurement error of a space filter for brightness due to solar light and lighting by compensating for change in luminance of an image accompanied by driving by using a deflection of an output of two grating-shaped space filters with different phases.

Title: Writing unit with countermeasure to power break
Inventor: FUKUI KOUICHI
IPC: G11B19/04
Filed: 1978-08-28
Abstract: PURPOSE:To enable a simple constitution to stop the operation of a writing method when a power voltage falls in level, by controlling a transistor via a Zener diode whose across voltage corresponds the fall of the power voltage. CONSTITUTION:Once power voltage +V1 falls, a voltage across Zener diode ZD2 corresponding to voltage +V1 also falls to cut off a current through transistor Q1, and transistor Q2 turns OFF. Therefore, a write output of JK type FF3 corresponding to write data is never applied to magnetic head 2 and regardless of the write enable state by buffer circuit 1, the simple constitution stops the writing operation while the power voltage is low, so that the breakdown of magnetic recording data due to the inflow of an error write current can be prevented.

Title: Cascade bi-mos short-circuit protection circuit
Inventor: TABATA MITSUHARU
IPC: H03F1/42
Filed: 1987-04-27
Abstract: PURPOSE:To prevent the destruction of a component due to a steep trailing by increasing the drive electric charge at the short-circuit protection through the use of a capacitor so as to slow down the turn-off speed of the component. CONSTITUTION:If the cascade Bi-MOS1 is short-circuited, it is detected by a short-circuit detection circuit (not shown in a figure) to turn on a photocoupler 5. Then an off-signal is outputted from the detection circuit to a drive circuit 2, which is activated thereby applying off-drive to the cascade Bi-MOS1. Since the drive circuit 2 has to drive the electric charge of the capacitor 3 in addition to the cascade Bi-MOS 1, the turn-off speed is retarded. Thus, the destruction of the component due to steep trailing is prevented.

Title: Packaging machine and bag-making machine
Inventor: TABUCHI KUNIHIRO
IPC: B65B9/06
Filed: 1990-04-19
Abstract: PURPOSE:To obtain a packaging machine which performs packaging with high strength by heat-sealing the same spot assuredly by a method wherein a first end seal to perform first heat-seal on a moving means, a second end seal to perform second heat-seal at the first sealed part, and a cutter to cut the sealed part are provided. CONSTITUTION:When an article A moves on a transfer means 1, negative pressure is added to the article A by a suction mechanism 3, and the article is adhered on a transfer means 2. Therefore, while the article is moving on the transfer means, even if thermal shrinkage is generated on a packaging film by being heat-sealed, or movement accompanied with the shrinkage is generated, the carrying position in the moving direction does not change. For this reason, a second heat-seal 52 can be accurately lapped on a first sealed part S1 sealed by a first end seal 11. By lapping heat-seals accurately on the same spot this way, hard to break heat-seal with sufficient strength can be performed. If the sealed part is cut by a cutter 17 after completing heat-seal by a second end seal 14, an article individually packaged by a synthetic resin film (f) can be obtained.

Abstract: PURPOSE: To provide a laser beam of high stability by a method wherein at least one of a pair of laser ray amplifying mirrors is made to be a partly transmissive mirror, and the vicinity of the output surface of the mirror is made higher than the atmosphere in pressure. CONSTITUTION: Air 9 is introduced into an inlet pipe 6 from an air feeder 13 so as to keep the vicinity of the laser beam outputting surface of a partly transmissive mirror 3a higher than an ambient atmosphere in pressure. As the vicinity of the laser beam outputting surface of the mirror 3a is higher than an ambient atmosphere in pressure, impurities such as oil mist present in the air in the vicinity of the laser beam output surface of the partly transmissive mirror 3a are restrained from approaching the vicinity of the mirror 3a and hardly attached to the laser beam output surface of the mirror 3a. By this setup, the refractive index of the partly transmissive mirror 3a and the divergence angle of a laser beam 4 in an initial state can be kept unchanged.
