Title: Shaft seal device for compressor
Inventor: KOJIMA YOSHINOBU
IPC: F16J15/10
Filed: 1987-02-17
Abstract: PURPOSE:To improve sealing performance, by providing an O ring in a grooved part which is formed by a reverse L-shaped groove, provided in a plate ring in its atmospheric side, and by a ringshaped disc, having an internal diameter larger than the small contour part of the reverse L-shaped groove, in its atmospheric side. CONSTITUTION:An O ring 5, which is placed being put between a plate ring 2 and a ring-shaped disc 15, is always compressed by a pressure of sealed fluid. Since the compressed force of the O ring 5 acts in directions of its contact surface with a housing 4 and a cylindrical surface of the plate ring 2, the pressure of these contact surfaces is generated in proportion to the pressure of sealed fluid, and since the more is improved the sealing action the higher the pressure of the sealed fluid increases, the O ring 5, even if its rubber material elastic force weakens, is prevented from deteriorating the sealing force.

Title: Ink ribbon cartridge
Inventor: MORIYAMA HITOSHI
IPC: B41J32/02
Filed: 1990-02-16
Abstract: PURPOSE:To reduce variation in a drawing force of an ink ribbon and to improve a printing quality by providing an engaging member for engaging at least the vicinities of both sides of the folded ribbon near the ribbon exit in a ribbon cartridge, and setting the height of the member to the degree that the ribbon can be passed through.

Title: Drive circuit for light emitting element
Inventor: TAKADA HISASHI
IPC: H04B10/40
Filed: 1984-02-24
Abstract: PURPOSE:To drive a light emitting element at a speed of several hundred mega bits or more per second by connecting a semiconductor switch element in parallel to the light emitting element and makes said switch element conductive when the light emitting element is turned off in order to secure the discharging path of the electric charge stored in a parasitic capacity Cd of the light emitting element. CONSTITUTION:When a drive input pulse 3 has a rise, a transistor TR1 is turned on and conducts to supply a drive current to a light emitting element 2. Thus the element 2 emits light. While a TR3 is turned on and works in the same way as a normal current switching circuit. However the TR1 is turned off when the pulse 3 has a fall. Thus the collector current is cut off. At the same time, the TR3 is turned on to discharge quickly the electric charge stored in a parasitic capacity Cd of the element 2. Thus the element 2 is turned off. As a result, the fall time of an output pulse of the element 2 is extremely reduced. This attains the high-speed pulse drive with several hundred mega bits or more per second.

Title: Position detecting device
Inventor: MORITA MITSUHIRO
IPC: G03F9/00
Filed: 1985-02-25
Abstract: PURPOSE:To enable a high-precision position detection of a wafer in the exposure process of photoresist coated on the wafer by using a semiconductor laser as the luminous section and a one-dimensional light sensor as the photodetecting section. CONSTITUTION:A semiconductor laser constituting the luminous section 4 prevent the inexact position detection of a wafer 2 by giving a small, beam-spot diameter to sharpen the detection signal. Further a charge-coupled device, a one-dimensional light sensor, is used as the photodetecting section 9 which is of the structure that the position and the intensity of the beam spot focused on the section 9 are digitally detected with a high precision. For this reason, the exact position of a laser beam image is detected with a high precision by identifying the original image point of the beam spot in the photosensitive section 9, even when comparatively low intensity images appear in the periphery of the original image due to comatic aberration of a lens group constituting the optical systems 5, 8 in the light path, with a method to discriminate accompanying image points by applying a prescribed threshold value to the intensities detected at these points.
