IPC: H02M5/12
Filed: 1994-09-02
Abstract: PURPOSE: To provide a compact control type power conversion device which can perform the synchronizing control and fast operations. CONSTITUTION: The control type power conversion device is provided with a primary winding 100 and a secondary winding 200. The winding 100 has a fixed number of turns and receives a constant voltage AC. The winding 200 consists of plural coils 201, 202..., and the terminal voltages V01 , V02 ... of coils 201, 202... are discretely switched by a digital control signal D. At the same time, the polarity of the output voltage V0 , i.e., the total value of voltages V01 , V02 ... is also switched so that the variable voltage V0 is obtained. Thus, it is possible to change the electric power by changing the output voltage V0 of the winding 200 against the AC input voltage V1 of the winding 100.

Title: Optical communication system
Inventor: WATANABE SHIGEKI
IPC: H04B10/556
Filed: 1991-09-13
Abstract: PURPOSE:To suppress the phase noises in a simple circuit constitution without using any wide band detection circuit. CONSTITUTION:The optical modulation is carried out at the transmitter side with use of a synthetic signal 104 obtained by multiplexing a transmitted signal 101 and a no-modulated signal 102 set out of a frequency band. The modulated light 106 undergoes the optical heterodyne detection, etc., through a photodetector means 107. A demodulator means 111 demodulates the signal 101 based on the electric signal 108' which is delayed by a delay means 110 by an extent equal to the time delay of a no-modulated component extractor means 109 and the no-modulated signal 112 which is extracted by the means 109. The receiver side is not required to receive the component of a wide frequency band covering the frequency component of the signal 101 through the main carrier component. The signal 101 can apply the data signal on the base band of a coherent optical communication system or the data signal which undergone the frequency multiplexing at a microwave level of a coherent SCM optical communication system.

Title: Retransfer sheet
Inventor: YAMANE MITSUO
IPC: B41M5/40
Filed: 1988-09-19
Abstract: PURPOSE:To enable a transfer image printed on a good wettable surface to be excellently retransferred by a method wherein a finishing agent which has an elongation of 100% or over and contains polyethylene fine powder is used on a retransfer sheet to be printed. CONSTITUTION:A finishing agent layer 12 has an elongation of 100% or over and contains polyethylene fine powder in composition. Since a finishing agent is thus unilaterally elongated by pressurizing in retransfer time, adhesion between the finishing agent layer 12 and an image 13 weakens. The finishing agent layer 12 contains one kind or two or more kinds of mixtures of polyethylene, ethylene-vinyl acetate copolymer, ethylene-ethyl-acrylate copolymer, ethylene-acrylate copolymer, etc. as a main component. Since wettability of the finishing agent becomes 80 deg. or under and a retransfer property is deteriorated in the case where a good wettable material (a contact angle to water of 80 deg. or under) is used in order to give elongation, the contact angle to water is taken as 80-120 deg. by adding polyethylene fine powder into composition of the finishing agent layer 12.

Title: Production of electrode wire for electric discharge machining for cutting wire
Inventor: YOKOTA MINORU
IPC: C23C2/06
Filed: 1982-12-27
Abstract: PURPOSE:To obtain an electrode wire having a good electric discharge characteristic at an increased working speed in a method for passing a core material of a copper alloy, steel, etc. through a molten bath of zinc, Cd, etc. and their alloy and obtaining a coated composite wire by cooling the wire while preventing its oxidation in the outlet of the bath. CONSTITUTION:A core material 2 is passed in a molten bath 4 of a high vapor pressure metal such as Zn, Cd or the like or the alloy thereof and is pulled from the outlet of the bath 4 while it is cooled to prevent oxidation by non-oxidative gas or liquid of a low temp. in said outlet. For example, a jig 7 is used, and non-oxidative gas such as N2, CO2, natural liquefied gas or the like is supplied through a blow port 8 thereof from directions 9, 9' and the core material is cooled from the surface of the covering. The thickness of the covering layer 10 is then made substantially thick and the high speed coating is made possible. The speed at which the material 1 passes the bath 4 is high and therefore the formation of the intermetallic compd. between the material 1 and the layer 3 is obviated. A composite electrode wire 6 having a good electric discharge characteristic is thus inexpensively produced.

IPC: H01L21/027
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To improve a throughput of an aligner. SOLUTION: A plate carrier PC1, containing a glass plate PT carried to an exposure processing section PE, is received in a subchamber SC separately from a main chamber MC receiving an exposure processing section PE transferring a reticle pattern to a glass plate PT by almost shielding from outside air.

Title: Developing device
Inventor: AOSHIMA MIGAKU
IPC: G03G15/08
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To stably and sufficiently maintain developer electrification capability over a long period of time by supplying carrier or developer whose amount corresponds to an amount of supplied toner, and also discharging used developer. SOLUTION: When a cartridge 5a is replaced with fresh one, a replenishment control means 7 replenishes a development housing 2 with a fixed amount of carrier or developer (an amount matching an mount of toner in the cartridge 5a). On the other hand, a discharge control means 8 carries e.g. by a developer carrying member 4, used developer in a direction opposite to that used for a normal operation, thereby leading the used developer into the position of a developer discharge means 6, and discharging by a developer discharge means 6 the developer whose amount corresponds to that of the newly added carrier or developer. In the case, the timing of the start of the operations of the replenishment control means 7 and discharge control means 8 are set on condition that the cartridge 5a is loaded in a toner/carrier replenishment means 5.  This prevents the developer from being supplied insufficiently or excessively and maintains the electrification capability.
