Title: Electric discharge lamp lighting device
Inventor: NISHIMURA KOJI
IPC: H05B41/16
Filed: 1989-08-28
Abstract: PURPOSE:To improve the life characteristic of a high-pressure electric discharge lamp by giving such a load characteristic that approximately parallels the equi-brightness characteristic of the high-pressure electric discharge lamp and also passes through a brightness point equaling the highest brightness point of the high-pressure electric discharge lamp to the lamp. CONSTITUTION:For the purpose of restraining a local temperature-rise in a luminous tube, such a characteristic that a tube voltage Vla and a tube current Ila, both being at least not less than a rated voltage Vo1, agree mutually on the equi-brightness characteristic of a high-pressure electric discharge lamp DL, namely, a load characteristic may be approximately equalized to the equi-brightness. For this purpose, a voltage corresponding to the tube voltage Vla of the high-pressure electric discharge lamp DL is detected by a circuit comprising a transformer Tf1, a full-wave rectifier DB2, capacitors C11, C12 and resistors R15, R16 to be entered into the terminal 4 of an IC controlling the switching action of a transistor. Namely, the ON-duration of the transistor is varied with the level of tube voltage Vla of the high-pressure electric discharge lamp DL by the use of a comparator output to make the tube voltage Vla constant when the tube voltage Vla is not less than the rated voltage Vo1. This improves the life characteristic of the high-pressure electric discharge lamp.

Title: Pulse amplifier circuit
Inventor: MUKOGAWA MASASHI
IPC: H03K5/02
Filed: 1988-09-05
Abstract: PURPOSE:To form an amplifier which can make amplifying operations at a high speed and is low in impedance by connecting two transistors of the same conduction type with each other in the form of a totem pole through a diode and, at the same time, connecting the base of the upper transistor to the collector of the lower transistor. CONSTITUTION:Two transistors(TR) Q1 and Q2 of the same conduction type are connected with each other in the form of a totem pole and, at the same time, the base of the TR Q1 to the collector of the TR Q2 and input signals are supplied to the base of the TR Q2. when a high level signal is supplied to an input terminal 1, the TR Q1 is turned on and an output terminal O become low in level. In this case, the TR Q2 is turned off, because the base of the TR Q2 becomes low in level. When a high-level signal is supplied to an input, the TR Q1 is turned off and the base of the TR Q2 becomes free. As a result, an electric current is made to flow to the base of the TR Q2 by means of a base resistance R and the TR Q2 is turned on. A high- level output signal is supplied to the output terminal O. The transition from the turned- off state to the turned-on state of the TR Q2 has no relation with the input, but is decided by the electric current made to flow by means of the base resistance R and characteristics of the TR Q2. Therefore, when a high-speed transistor is used for the TR Q2, arm acute pulse waveform can be obtained.

Title: Water-base peeling agent
Inventor: TSUDA TORU
IPC: C09J7/02
Filed: 1989-08-30
Abstract: PURPOSE:To obtain a water-base peeling agent which has good shelf stability and can be used even for a pressure-sensitive tape or sheet made from a base material sensitive to high temperature since high-temperature treatment is not necessary by post-emulsifying a specified long-chain alkyl graft polymer. CONSTITUTION:A polyalkylene-imine or polyalkylene polyamine is reacted with an alkyl isocyanate to give a long-chain alkyl graft polymer, which is post-emulsified to form an aqueous dispersion. The aqueous dispersion is used to produce a water-base peeling agent. This peeling agent has good shelf stability and can be used even for a pressure-sensitive tape or sheet made from a base material sensitive to high-temperature treatment because there is no necessity for reaction in the drying step after application so that high- temperature treatment is unnecessary. Although of water base, it has properties comparable to those of solvent-base peeling agents widely used in general, is excellent in applicability and transparency, and can be utilized for, e.g. treating the rear of pressure-sensitive tapes or sheets made from a wide variety of base materials such as paper and various plastic films.

Title: Contrivance for observation method of correlation between atoms in giant molecule
Inventor: TOKUDA KAZUYOSHI
IPC: G01N24/08
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To observe correlation between atoms of a giant molecule by irradiating a giant molecule sample with a vibration magnetic field in the mingling of longitudinal magnetization by a specified method. SOLUTION: In the irradiation of a giant molecule sample with a vibration magnetic field in the mingle of longitudinal magnetization, a vibration magnetic field is applied at 1/the rotary frequency of the sample to change the direction of the magnetization by 180 deg.. When this method is applied for a giant molecule, a very short vibration magnetic field is applied quickly in succession to change the direction of the magnetization by 180 deg. to allow observation of even the giant molecule. The use of the means as mentioned above makes it possible to obtain information between three to four atoms. This suggests the possibility of obtaining highly approximate results even when the molecular weight becomes by far larger as in the case of the giant molecule.  Especially, there is a high possibility of obtaining information on the structure of the molecule by obtaining information between the two atoms using the means. This means can be utilized for infrared spectroscopy, electron microscopes or others.

In a hot water washing process, a water feed valve 23 is opened to feed water in the cleaning tank 3 and the washing water mixed with cold water therein is circulated and stirred by operating a cleaning pump 12 for a predetermined time. The washing water is then drained out by operating the drainage pump 16 for a predetermined time. The washing water having a high temp. is thereafter cooled and drained out little by little by the cyclic action of the water feed, stirring and water drainage as mentioned above. Finally, the drainage pump 16 alone is further operated for about one minute to pump out all of the washing water having a sufficiently lowered temp.

Filed: 1984-10-25
Abstract: PURPOSE:To enhance the efficiency of transport, according to a method wherein a generator turns to generate an electromotive force signal so that a sequence circuit can direct the following action only when a product loaded on a transport roll touches a detection roll which turns in normal direction via a one-way clutch. CONSTITUTION:Products move inside a groove arranged along the external periphery of a detection roll 3, both ends of the shaft 4 of the roll 3 are rotatably supported by the tip portion of a support plate 8 the projection of which is provided with a one-way clutch 5 fixed thereto and a generator 6 is further installed thereon. Since the roll 8 turns around its support pin 10 serving as a fulcrum the roll 3 can exactly follow the movement/stop of product M. When a push button PBS1 is pressed, a solenoid contactor MCF operates to cause normal turn of a transport roll 2 to get product M supplied. If the transport of product M is suspended as the result of judgement for wrong size of product M discovered by a measuring instrument 7 curing its contact with either roll 3 or the subsequent roll, the generator 6 stops to interrupt transmission of the electromotive force signal. Then, the roll 2 makes reverse turn, following the operation of the solenoid contactor MCR, so as to transport product M backward.
