Title: Counting method for linked overlapping continuous body
Inventor: SANO MITSUGI
IPC: G06M7/00
Filed: 1986-02-07
Abstract: PURPOSE:To exactly count the number of pieces of bodies even when they are consecutive overlapping continuous bodies by contrasting a speed signal with a detection signal. CONSTITUTION:Bodies to be carried with almost regulated shapes arranged in a line and carried on a consecutive carrying mechanism are detected with a count detector, and detection signals T equal to the number of bodies in appearance can be obtained. A flow velocity confirming signal (d) is generated by triggering with the detection signal, and furthermore, the input of a flow velocity signal tf measured in advance is triggered with the flow velocity confirming signal (d). And by contrasting the detection signal T with the flow velocity signal tf, a count signal equivalent to a piece of body is outputted when the detection signal T is shorter than the flow velocity signal tf, and in cases other than that, the T/tf-number of pieces of count signals are outputted. Since the number of pieces of the bodies to be carried are counted by contrasting the detection signal in appearance with the flow velocity signal in such a way, the true number of pieces of consecutive overlapping continuous bodies can be recognized exactly.

Filed: 1981-02-23
Abstract: PURPOSE:To prevent an Si substrate and an aluminum wiring from mutual dispersion by providing a silicified platinum layer between them, and also to prevent an SiO2 membrane from exfoliation by providing an aluminum pad on its surface. CONSTITUTION:A base emitter layer is formed on an Si substrate 1. As for the emitter layer, SiO2 4 is provided with an opening, Pt is attached by soldering and heated to selectively form Pt-Si layer 6 so as to prevent mutual dispersion between Si and Al. And then, a wiring layer for two layers of Mo 7 and Al 9 is provided, covered with SiO2 10 and an opening 11 is selectively provided. An Al wiring 12a and a joining pad 12b for the second layer are provided at the opening, and an Al  wiring is joined to the pad 12b by supersonic wave. In this mechanism, since the Al pad 12b and the SiO2 membrane 4 are joined together directly, the joining strength become large, and in the case of a thermal oxide membrane, in particular, since the membrane is much harder than a CVD membrane, the joint is ensured. Further, as compared with an Al-Mo dual structure pad, possibility of exfoliation of the pad becomes as small as less than 1%.

Title: One-pack latent curing agent for epoxy resin
Inventor: HIRAI KIYOMIKI
IPC: C08G59/44
Filed: 1989-02-02
Abstract: PURPOSE:To obtain a latent curing agent for giving an epoxy resin which is excellent in storage stability at room temperature, can be cured within a short time by heating, can give a cured object excellent in properties such as toughness and adhesiveness, and comprises a salt of a specified cyclic compound with a dibasic acid. CONSTITUTION:The title cursing agent comprising a salt of a 3,9-bis(aminoalkyl)-2,4,8,10-tetraoxaspiro[5,5]undecane of the formula (wherein X is a 1-6C branched or linear alkyl residue), e.g. 3,9-bis(aminopropyl)-2,4,8,10- tetraoxaspiro[5,5]undecane (hereinbelow referred to as ATU) with a dibasic acid (e.g. succinic acid or adipic acid). Although ATU can give a cured product excellent in impact resistance, weathering resistance and adhesiveness and therefore extensively used as a curing agent for epoxy resin, it is necessary to perform metering, mixing, defoaming, etc., just before use when it is mixed with an epoxy resin. By converting it into a salt with a dibasic acid, an epoxy resin composition containing it scarcely reacts at room temperature, and it can be rapidly cured by heating without forming any volatile matter.

Title: Halogen lamp lighting device and image formation device using this device
Inventor: ENDO SATOSHI
IPC: H05B39/04
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To sufficiently restrain flickers occurring during initial periods of the lighting of a halogen lamp. SOLUTION: Before lighting, the impedance of a halogen lamp 4 is measured by an impedance measurement circuit 8 so that the operation period of lighting means 2 in the initial stage of lighting is determined according to measurement values. When a lamp lighting signal is turned on, a lamp lighting control device 7 initially transmits a PWM control signal to a two-way switch 6 of the lighting means 2, which is changed to an operating condition. When said operation period elapses, a PWM signal is turned off to change the lighting means 2 to a non-operating condition, and a signal is transmitted to a photocoupler 3 to change lighting means 1 to the operating condition.  In the initial period of lighting, a current chopped by the two-way switch 6 flows into the halogen lamp 4, however, high frequency components of the current are cut off by a LC low-pass filter 5 to suppress the amplitude of a rush current. Said operation period is properly determined according to the impedance of the halogen lamp 4 before lighting.

Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce the number of opening and closing valves and simplify constitution of a valve shape of a pressure control part, arrangement of a piping, etc. SOLUTION: In the case when a main compressor 5 carries out compression work, an opening and closing valve 6 comes to be in a closed state, and as a check valve 41 prevents flow of fluid from an auxiliary compression part 21 to a discharge pressure chamber 43, the side of a discharge pressure chamber 23 of the auxiliary compression part 21 comes to be in a closed state. Additionally, as a high pressure refrigerant flowing out of a discharge side of the auxiliary compression part 21 is supplied to a back pressure chamber 17 through a passage 24, a pressing member 16 causes pressing force, and main and auxiliary friction plates 12, 13 are connected to each other. Consequently, rotation of a rotation axis 6 is transmitted to an input crank 3, and the main compressor 5 starts compression work.  In this way, as the check valve 41 is provided in place of the conventional opening and closing valve, it is possible to simplify constitution and to increase freedom in arrangement of a piping.
