IPC: B26F1/26
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To cause a jumping body to clash with an impact material without disturbing an impact environment such as a temperature condition or an atmosphere by connecting a positive polarity cylinder for inserting the jumping body and a negative polarity together by a high-voltage large current power source. SOLUTION: Power is inputted between a positive polarity cylinder 5 and a negative polarity 11 by a high-voltage large current power source 61. Then, electric discharge occurs in an evaporation space 9 in an insulating cylinder 8 provided between the positive polarity cylinder 5 and the negative polarity 11, evaporation occurs in the insulating cylinder 8 inside the evaporation space 9 because of a heat generated by electric discharge and thereby high-temperature and high-voltage gas is produced, and by the pressure of the gas, a jumping body 1 is accelerated together with an acceleration auxiliary jig 15. Only the jumping body 1 is passed through a servo separation hole small hole 21 and shot from the tip of the positive polarity cylinder 5.  The jumping body 1 is caused to clash with a test piece in a sealed type canister and thus impact testing is performed for the jumping body 1 and the test piece.

Title: Longitudinal member structure in tank
Inventor: NISHII YUICHI
IPC: B63B3/62
Filed: 1993-03-03
Abstract: PURPOSE:To provide the structural system of a longitudinal member without generating the accumulation of liquid on the upper face of the longitudinal member in a tank when the liquid is drawn out of a liquid tank. CONSTITUTION:A longitudinal member is fitted to a tank side wall body 3 in such a state that the flange 1 of the longitudinal member is inclined downward and the web 2 of the longitudinal member is inclined so as to have 3 deg.-10 deg. in the angle of depression. As a result, when liquid in a tank is discharged, the liquid flows down from the inclined face of the web 2 so as not to be accumulated on the longitudinal member. With the inclination of 3 deg.-10 deg. in the angle of depression, there is no need to sharply enlarge the cross-sectional dimension of the longitudinal member. Also, since there is no need to provide the web face with drain holes, manhours for boring and a troublesome coating process performed for the holes can be reduced.

Title: Gas leak alarm
Inventor: KUME KAZUTO
IPC: G08B21/00
Filed: 1990-02-23
Abstract: PURPOSE:To decrease erroneous alarm and to improve reliability by arranging plural gas sensors at mutually separated positions, and generating the alarm only when almost simultaneously detecting gas detection signals from more than two gas sensors. CONSTITUTION:A gas detector 7 of an auxiliary sensor part 6 is installed at the position separated from a gas detector 2 of a main body part 1. The main body part 1 monitors and drives the detectors 2 and 7 through gas detector drive monitor circuits 3 and 8. In the case of a gas leak, the gas stagnates in a room and the detectors 2 and 7 detect it almost simultaneously. In the case of the gas in a spray, etc., however, even when one of the detectors 2 and 7 detects the gas, both detectors 2 and 7 do not detect the gas almost simultaneously. Therefore, only when the gas detection signals are detected almost simultaneously from more than two gas sensor parts, the alarm is generated. Therefore, the erroneous alarm is decreased and the reliability is improved.

Title: Production of roughened polypropylene film
Inventor: NAGOU KUNIYA
IPC: C08J7/02
Filed: 1981-03-26
Abstract: PURPOSE: To obtain a roughened polypropylene film excellent in diffusibility of an oil, such as insulating oil or dielectric oil, over the surface, by washing a stretched polypropylene film with an organic solvent which does not dissolve polypropylene.  
     CONSTITUTION: A stretched polypropylene film is washed with an organic solvent which does not dissolve polypropylene. As a polymer for the stretched polypropylene film, there is preferably used a polypropylene homopolymer becuase it has good electrical properties, strength and high roughness of a film surface. Especially, a stretched polypropylene film prepared by biaxial stretching is preferred, because such a film has high strength, and uniform network-form irregularity can be formed on the film surface and, therefore, it becomes possible to obtain surfaces having good oil diffusibility by washing with an organic solvent. As the organic solvent, there is preferably used an alcohol such as methanol, a ketone such as acetone or an ether such as methyl ether.

Abstract: PROBLEM TO BE SOLVED: To easily set a target satellite frequency, even if plural frequency shift systems exist by detecting a carrier signal in any of plural specific frequencies that have been defined preliminarily and specifying the type of a frequency shift in a community antenna. SOLUTION: A frequency is selected from among plural stored specific frequencies and is set as a selected frequency, when a community antenna system setting is selected. When a carrier signal is detected by selecting a channel, the ID of a transport stream(TS) described in a program association table and the ID of a TS corresponding to a satellite frequency in a network information table are acquired. When the ID that has been actually selected matches the ID allocated to the satellite frequency, one specific frequency can be specified among plural assumed specific frequencies, and the type of a frequency shift can be identified.

Title: Insufficient braking detection system for atc
Inventor: HASEGAWA HIROICHI
IPC: B60L3/08
Filed: 1978-04-13
Abstract: PURPOSE: To detect the insufficient level of braking force fail safe by discriminating the conincidence of actions between an ATC brake output relay and a deceleration detection relay.  
     CONSTITUTION: When there is no ATC braking command, the relay NBR is  energized while the relay deenergized. Thus, the relay FR is energized. When an ATC receiver 1 receives the ATC braking command, simultaneously with the deenergization of the relay NBR, a deceleration detector 4 detects reduction in  speed. If a given braking force is applied within a given time, the relay BFT is  energized while the energization of the relay is maintained. When no given braking  force is produced after a given time, the relay BFR fails to be energized while the  relay FR is deenergized whereby the brake is commanded to apply the energency  braking.

Filed: 1992-02-28
Abstract: PURPOSE:To changeover an operation program without interruption of communication by continuing the processing of an old program for a call received before input restriction and executing a changeover procedure to a new program after that. CONSTITUTION:In the communication processing unit provided with line adaptor interface devices 20, 21 accommodating a communication line 30 and processing units 10, 11 including a processor CPU, when the operation program is changed over, input is restricted to the devices 20, 21.
