Title: Pcm reception system
Inventor: TAKAHASHI SUSUMU
IPC: H04B14/06
Filed: 1985-04-12
Abstract: PURPOSE:To compensate effectively the deviation of DC component due to missing of difference data in a system such as DPCM system by applying DC feedback to an integration means for integrating a digital difference data and for converting the result into linear PCM data. CONSTITUTION:A coupling means 13 adds output data of a data register 14, that is, output data of the coupling means 13 before one sample to a difference data given from an input terminal 11, subtracts an output of a division means 22 from the said difference data and outputs the result. Further, the result is outputted to an output terminal 17 via a D/A conversion means 16. An integration circuit 16 discriminates a DC level in this case and feeds back the result to a division means 22 and the conversion means 23, then the DC level of the digital integration means 12 is kept nearly zero and even when missing of PCM data takes place, the DC level is restored to zero.

Title: Production of high-molecular weight unsaturated polyester
Inventor: NIIKURA ISAMU
IPC: C08G63/78
Filed: 1995-04-03
Abstract: PURPOSE: To obtain at lower cost a high-molecular weight unsaturated polyester well-balanced in boiling water resistance, toughness and heat distortion temperature. CONSTITUTION: In producing this polyester through esterification between an α,β-unsaturated polybasic acid, a saturated polybasic acid and polyhydric alcohols followed by deglycolation, the production process is made up of the following two steps: 1st step: 1,6-hexanediol as part of the polyhydric alcohols accounting for 5-50mol% of the polyhydric alcohols is used and esterified with the saturated polybasic acid to an esterification conversion rate of >=60%; and 2nd step: the α,β-unsaturated polybasic acid is added to the reaction system and a further reaction is conducted. In the 2nd step, when the acid value of the reaction system comes to 90-15, the pressure is reduced to 93-7hPa to carry out the deglycolation to bring the number-average molecular weight of this polyester to >=4000.

Title: X-ray mask and its manufacture
Inventor: ARAKI SEI
IPC: G03F1/22
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray mask having an alignment mark of high precision lattice pattern. SOLUTION: An alignment mark is constituted of recessed parts and protruding parts which have a plane littice type formed on the surface of an X-ray transmission film 2 by etching. X-ray absorber 3 composed of a Ta film is burried in the recessed parts. Since the X-ray transmission film 2 is constituted of the protruding parts and the recessed parts, and a vissible light reflecting film is buried in the recessed parts, the vissible light casted on the alignment mark generates reflected diffraction light. Since a vissible light transmission film and the vissible light reflecting film are in contact with each other, and the surface part is flattened, a pattern is not inclined by the self-weight or the stress distribution. Thereby a high precision lattice pattern which is arranged at constant pitches on the same plane can be formed, and does not cause alignment error.

Filed: 1989-03-29
Abstract: PURPOSE:To sharply reduce an afterimage of a phototransistor in a charge storage mode by driving the phototransistor operating in the charge storage mode by making desired charge flow into its base electrode. CONSTITUTION:In a phototransistor making a collector to operate as an access terminal and an emitter as an output terminal of an image signal, a base electrode thereof is made to introduce desired charge into a base electrode in the read timing or in the timing of a part of a storage period. Accordingly, not depending on hyteresis of a read picture, voltage between the base and the emitter of the phototransistor immediately before read is maintained at desired fixed value, the maximum value of nonlinear resistance value according to a diode between the base and the emitter interposed in a recharge circuit can be set to desired value and at the time of recharge, the maximum value can be suppressed to the appropriate value. Thereby, an afterimage rate is improved while preventing the lowering of distinction in a read picture signal.

IPC: F02M37/10
Filed: 1992-02-28
Abstract: PURPOSE:To provide an electric circuit vessel hardly undergoing electric erosion, and further provide a fuel pump for a vehicle using the vessel. CONSTITUTION:A terminal through-hole 79 drilled through the disc 74 of a vessel 76 is surrounded with a circumferential wall 80 for forming an expanded step section 79a. Thus, a creeping distance between a connection terminal 78 inserted through the center of the hole 79 and the circumferential wall 80 can be increased, and the electric erosion of the terminal 78 can be reduced. As the expanded step section 79a is formed with the wall 80, the strength of hermetic glass 81 inserted and caulked around the terminal 78 does not drop, and the holding strength and the holding position accuracy of the terminal 78 can be maintained. In mounting an end cover 91 on a vehicle fuel pump 1, the circumferential wall 80 is coupled to the wiring hole 97 of the cover 91, thereby enabling the end cover 91 and the vessel 76 to be easily aligned with each other and prevented from turning.
