Title: Image forming device
Inventor: ISOGAI TAKASHI
IPC: G03G21/14
Filed: 1988-11-09
Abstract: PURPOSE:To speed up image formation regardless of a fixing speed by handling a sheet sent from a transferring part in the way that it is surely conveyed to a fixing part without affecting transfer and fixed at the proper speed of the fixing part. CONSTITUTION:In the transferring part, a developed image on a photosensitive body 11 is transferred on the sheet 56 simultaneously conveyed with the image at a system speed.

Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To decompose and clean off the contaminant stuck to the photocatealyst film of a member by activating the film with a high-pressure discharge lamp emitting a light in a specified wavelength range. SOLUTION: When a member provided with a photocatalyst film is cleaned, the photocatalyst film 2 provided to the light-transmissive glass member is irradiated with the emission of a high-pressure discharge lamp 3 formed by sealing a discharge medium contg. the halide of a light emitting metal having an excited resonance line in 340-360 nm wavelength range and a rare gas in a light-transmissive airtight vessel and activated. Consequently, the contaminant on the film 2 is cleaned off. Further, as the UV in this range is only slightly absorbed by the glass even if the member 1 is a light-transmissive glass member, the visible light transmittance of the member 1 is not lowered by the coloration of the glass due to polarization, and the member 1 is not discolored or deteriorated by the UV absorption even it is a synthetic resin etc.

Abstract: PURPOSE:To shorten a carrying time and to efficiently use an exposure device, by guiding a photosensitive material exposed and ejected from the exposure device to the carrier path of the device, and carrying it smoothly at the same speed as the carrier speed in the exposure device. CONSTITUTION:The length of the carrier path 36 is formed longer than the photosensitive material 12 of maximum length used in the exposure device 4, and a one-way clutch to which a driving force from a driving source is transmitted only in a direction of carrying and which generates slip in the direction of carrying when an external load in the direction of carrying is applied and suppresses itself from functioning as the resistance of the carrying, is attached. The carrier speed is switched appropriately to first speed same as at least the travel speed of the photosensitive material 12 in the exposure device 4, and to third speed faster than the first travel speed and second speed that is the travel speed of the photosensitive material 12 in a developing device 6. Generally, the carrying is performed at the first speed, and it is performed at the third speed during a time until the tip of a sheet-shaped photosensitive material 12 in which exposure is applied arrives at the entry of the developing device 6. In such way, it is possible to efficiently use the exposure device.

Then, low power laser light is partially projected on the a-Si film 30 and annealing is performed. thus crystallized parts 51-53 and the like are formed. Said crystallized parts are made to be low resistance parts by the crystallization. Parts 6 on the transparent electrodes 21 and 22 and the like neighboring the crystallized parts are removed. The parts are divided into the a-Si films 31 and 32 and the like and transparent conductor films 26 and 27 and the like. Back surface metal electrodes 41 and 42 and the like are formed through an evaporating mask. Therefore, a photoetching process for the back surface metal electrodes, which has been performed in conventional procedure, can be omitted. Thus the manufacturing processes is simplified to a large extent.

Title: Digital signal processing system
Inventor: EGAMI TAKESHI
IPC: H04B1/10
Filed: 1993-11-15
Abstract: PURPOSE:To prevent performance from deteriorating by inserting a delay circuit in one of outputs of a reference oscillator so as not to locate the output signal change point of a digital signal processing circuit in the phase comparison period of the phase comparator output of a frequency synthesizer. CONSTITUTION:A clock signal C1 from a reference oscillator 1 is frequency- divided into a reference signal C2 by a 1/N frequency divider 2, and it becomes the reference signal of the frequency synthesizer 3. On the other hand, delay circuit output C3 that is a clock set as reference inputted to the digital signal processing circuit 4 is delayed by constant time by a delay circuit 15, and it becomes a signal whose phase is shifted. A digital signal D1 is also delayed by a constant time by operating the digital signal processing circuit 4 setting the output C3 as the reference. Consequently, it follows that the change point of the signal D1 is located in the holding period of the phase comparator output, which prevents a noise in the phase comparison period.

Title: Production of glass cell
Inventor: NISHIGUCHI TADASHI
IPC: C03B23/08
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To produce a glass cell free from waviness in inner and outer surfaces which are optically important. SOLUTION: A mold 11 is inserted into a bottom-closed cylindrical glass container 10, and this is held in a state where the bottom face 10b is upward. Then, the glass container 10 is raised into a heating furnace together with the mold 11 having the bottom face 10b at the upper side while reducing the inner pressure. The side face 10c of the glass container 10 is heated to soften from the bottom face 10b toward the opening 10a. This allows the inner face of the glass container 10 to be formed along the mold 11 owing to the suction force of the inside of the glass container 10. Further, the outer face 10c of the glass container 10 is free from the generation of drooping toward the holding part by its own weight which may cause heavy waviness.
