Title: Image sensing device
Inventor: JIYAROSURABU HAINESETSUKU
IPC: H01L27/146
Filed: 1994-09-21
Abstract: PURPOSE: To avoid a vertically overflowing drain structure, to facilitate device manufacture and process parameter control, and to achieve high sensitivity, surface dark current suppression, and linear responsiveness improvement. CONSTITUTION: A change level is responsive to light incident on a device. During charge integration, a transistor gate 34 is biased negative, and charge is stored in a virtual potential well below drains 24, 26 which surround the gate 34. After the charge integration, the gate is biased higher so that a transistor gate well under the gate 34 may be at a higher potential than the virtual potential well. As a result, the charge is transferred from the virtual potential well to the gate potential well, and is used for detection by a charge sensor 28. By biasing the gate 34 negative after the detection, and then biasing a clear drain 30 and a clear gate 36 more positively, a charge is transferred from the transistor gate well to the virtual potential well, moreover causes it to cross a clear gate barrier under the gate 36, and causes it to flow out to the clear drain 30.

Title: Heat treatment of alpha+beta type titanium alloy
Inventor: MAEDA HISASHI
IPC: C22F1/18
Filed: 1984-10-30
Abstract: PURPOSE:To improve the ductility, especially the drawability of an alpha+beta type Ti alloy without reducing the strength by heat treating the Ti alloy to form martensite or a retained beta-phase and by well growing a beta-phase or the retained beta-phase by overaging. CONSTITUTION:An alpha-beta type Ti alloy is heated to a temp. in the alpha+beta type temp. range of 60 deg.C- the beta-transformation point (60 deg.C and the beta-transformation point are not included), and the alloy is held at the temp. for 0.5-2hr. It is then cooled at the air cooling rate or above to form a mixed structure consisting of a proeutectoid alpha-phase and martensite or a retained beta-phase by hardening. The hardened alloy is annealed at 600-800 deg.C to grow a beta-phase precipitated from the martensite by decomposition or the retained beta-phase. Thus, the drawability of the alloy can be improved remarkably without reducing the strength.

Patent JP-H0274149-A (JP)
Title: Chopper
Inventor: MATSUURA TOSHIAKI
IPC: H02M3/135
Filed: 1988-09-09
Abstract: PURPOSE:To suppress excessive increase of output voltage upon variation of input voltage by varying the response speed of a feedback control circuit based on the result of comparison with a preset reference voltage. CONSTITUTION:Output voltage is controlled to a constant level through a feedback control circuit 10. When the input voltage E0 increases to E1 and the output voltage V0 of a filter capacitor 8 exceeds over a second reference voltage Vth, a pulse signal P having time width between time points (t1) and (t2) is produced from a response speed modifying circuit 20. The pulse signal P reduces the value of the integration capacitor 18 in a voltage comparator 13 and increases the response speed of the feedback circuit 10. By such arrangement, the output voltage V0 is suppressed to prevent application of excessive voltage onto a load 19. When the output voltage of the filter capacitor 8 drops below the second reference voltage, the pulse signal P disappears and the response speed is reset to low level and thereby the feedback control system is not brought to unstable state.

Title: Operation controller for supercharger
Inventor: SUZUKI NORIO
IPC: F02B39/12
Filed: 1982-12-28
Abstract: PURPOSE:To prevent driving loss by placing an electromagnetic clutch between an engine drive supercharger and internal-combustion engine then controlling power supply to the electromagnetic clutch through a pressure switch to be turned off in low engine load region while stopping the supercharger under low load. CONSTITUTION:Under low engine load, relatively high suction negative pressure is fed through a pressure path 32 into a pressure chamber 28 in a pressure switch 24 thereby a diaphragm 26 is moved upward against a spring 36 to separate a contactor 42 from a terminal 44. Consequently power is not supplied to an electromagnetic clutch 18 and a supercharger 8 is stopped under declutched state. While upon increase of load to lower suction negative pressure, the diaphragm 26 is moved downward through a spring 36 to contact the contactor 42 with the terminal 44. Consequently said clutch 18 is clutched upon power supply to transmit the driving force of internal-combustion engine 2 through transmission containing a belt 14 and said clutch 18 to the supercharger 8 thus to activate it.

Abstract: PURPOSE:To reduce the transmission work by registering an identification number or the like of the other party as the telephone number of the other party. CONSTITUTION:The identification number or the extension number which designates the facsimile equipment of the other party connected to dial-in telephone is registered in a system control part 7, and the identification number or the extension number is sent a certain time after line connection, and transmission procedures are started after a certain time. Consequently, the operator on the transmission side can transmit data by the same operation as a normal facsimile equipment which is not connected to a dial-in telephone when transmitting data to the facsimile equipment connected to a dial-in telephone, and therefore, the transmission work of the operator on the transmission side is reduced.
