Title: Film stacking device and conveyor roller for development device
Inventor: OCHIAI KANENOBU
IPC: G03D15/00
Filed: 1990-10-01
Abstract: PURPOSE:To securely convey a leader and prevent a film from meandering by providing plural projection parts at the outer peripheral part of a nip roller and forming a ring groove in a driving roller. CONSTITUTION:The film 40, clamped between a roller 74 for leader conveyance and a roller 68 for film conveyance, is sent in between the nip roller 120 and driving roller 122. The projection parts 124 of the nip roller 120 abut on the tail end of the leader 46 which is sent in between the nip roller 120 and driving roller 122 and the leader 46 is sent out in its conveyance direction. Further, the leader 46 is clamped between the projection parts 124 and the ring groove 130 of the driving roller 122 and curved at right angles to the conveyance direction, so the leader 46 increases in rigidity. The leader 46 can securely be conveyed to a stacking plate 108 without curving in the conveyance direction. The highest nip pressure is obtained nearby the center part and the nip pressure decrease gradually outward in the width direction, so the film which is conveyed along the center part is prevented from meandering.

Title: Analog gate
Inventor: OKADA KATSUHIRO
IPC: H03K17/60
Filed: 1985-11-26
Abstract: PURPOSE:To attain proper gate operation even to a high frequency signal by connecting a diode conducted when a voltage of an ECL level or over is fed to the diode to a prescribed input terminal of an ECL and using the conduction/ nonconduction of the diode so as to stop or operate the amplification function to other input signal to the ECL. CONSTITUTION:When an ECL level signal is inputted to an input terminal I2 and a voltage of 5V is inputted to an input terminal I1, a diode 2 is conducted and an H level signal is outputted from an output terminal O1 as shown in figure (c) by the limiter operation of an ECL-IC 1 and an L level signal is outputted from an output terminal O2 as shown in figure (d). In applying a voltage of 0V to the input terminal I1, the diode 2 is reverse-biased and nonconductive, the amplification operation of the ECL-IC 1 is resumed and a signal fed to the input terminal I2 is outputted from the output terminal O2. An analog gate is constituted by using the ECL-IC 1 in this way, and since the ECL is high in the operation known widely, no crosstalk is caused even at high frequencies.

Title: Descaling method of washing machine
Inventor: TACHIBANA SHIGEMITSU
IPC: B08B3/02
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To inexpensively and rapidly remove the scale sticking to a punching plate of a washing machine by injecting a high-pressure water stream of a specific value in water pressure to the punching plate. SOLUTION: High-pressure washing with water is executed under a pressure of 98 to 194 MPa by using a special high-pressure pump used for descaling of metals. Of course, the scale removal may be rapidly suppressed as the pressure is higher but the punching plate is damaged in some cases by the material of the punching plate and, therefore, the pressure and the time for injecting the high-pressure water to the same place are required to be properly adjusted by the material thereof. The injection to the same place is executed for a time of preferably about 1 to 4 sec/cm<2> , more preferably 1 to 2 sec/cm<2> . As a result, the scale sticking to the punching plate may be rapidly removed without damaging the metallic surfaces.

IPC: B32B15/082
Filed: 1990-10-02
Abstract: PURPOSE:To obtain a composite metallic sheet in which the separation from a metallic layer does not occur even in the use for long time by composing the composite sheet of the double layer-film containing fluoroplastic composed of at least two layers and a metallic sheet. CONSTITUTION:The composite film containing fluoroplastic is composed of at least two layers, and one of them is the layer F1 containing colorant, and the other layer is the layer F2 containing almost no colorant, and then the layer F2 is preferably bonded onto the surface of the metallic sheet. By bonding the layer F2 onto the metallic sheet, the fusion of the layer F1 to the metallic sheet, which has been difficult up to now, may be achieved. The resin containing fluorine is the thermoplastic resin containing the fluorine in the molecule- constitutional formula of resin, and it is preferably tetraethylene fluoride resin. The resin containing fluorine to be used for the layer F2 may be used as the resin containing fluorine to be used for the layer F1. Since the metallic sheet and the film containing fluorine plastic are heated and welded under oxygen free atmosphere, the metallic sheet and the film containing fluoroplastic are not deteriorated by oxidations, whereby the composite metallic sheet provides high weld strength and enables the use for long time to be achieved.
