Title: Stroboscope charging circuit, stroboscopic device and camera
Inventor: TANIGUCHI HIDENORI
IPC: G03B7/16
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a battery voltage as a power source from considerably dropping during the time when a main capacitor is being charged, by cutting off the voltage supply of the power source battery to the step-up circuit by a switching circuit when the power source voltage drops to a prescribed level or lower, to miniaturize a back-up circuit, and to reduce the cost. SOLUTION: A sequence control circuit 26 keeps a CGCOM terminal at a level L, and starts charging a main capacitor 25. Since a switching circuit is a combination of two transistors 2 and 5, a voltage two times as high as a base-emitter voltage of each transistor is required as an operation voltage. Therefore, as compared with a conventional circuit, the switching circuit will not operate unless a voltage of a battery 1 is higher, so when a voltage drop occurs with the battery 1 as the voltage source or the battery 1 is decreased in capacitance, the operation of the sequence circuit 26 is secured without charging the main capacitor 25. Moreover, when the voltage of the battery 1 is recovered, the main capacitor 25 is restarted to be charged.

Title: Automatic cooking grill device
Inventor: YAMASHITA TADAO
IPC: F24C3/12
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent unsuitable cooking from being performed after the material of food is drawn by opening a door for checking the degree of grill during cooking due to an automatic grill device. SOLUTION: The temperature of food material F is measured by a temperature sensor 12 and when it becomes a prescribed cooking completion temperature, a controller 15 stops gas. In that case, a connector 13 to be linked with a door 8 is provided between the temperature sensor 12 and the controller 15 and when the door 8 is opened/closed, the connector 13 is opened/closed as well. Since the temperature of food material falls and following control gets unsuitable when the food material F is drawn by opening the door 8 for a long time, the gas is stoped when the opening time of connector 13 exceeds 30 sec, and control operation is stopped as well.

Title: Gas turbine rotor
Inventor: ICHIYANAGI TAKU
IPC: F02C7/18
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of cooling air by a seal means which does not cause abrasion and air leakage by butting the end surface of the tip part of one arm and the end surface of the tip part of an extension member of the other arm against each other, and putting both end surfaces in a compressed condition when plural disks are integrally formed. SOLUTION: The tip part 2 of an arm 1 arranged on one disk forms an inward bending cross-sectional shape. The inward bending cross-sectional-shaped extension member 4 of an arm 3 arranged on the other disk is installed by welding. An end surface 1a of the tip part 2 of one arm 1 and an end surface 3a of the extension member 4 of the other arm 3 constitute a pressure contact surface 6 by containing with each other. In an actual use condition, both arms 1 and 3 in the pressure contact surface 6 are brought into pressure contact with each other. Since sliding motion hardly exists in the pressure contact surface 6, abrasion is not caused.  When a rotor rotates, the center line deflects by its dead weight, and pressure contact force periodically changes in the pressure contact surfaces 6 on the tip of the arms, but since there is hardly any difference in being brought into pressure contact, air leakage is prevented.

Abstract: PURPOSE:To eliminate the generation of the defective appearance of a glass section by constituting a sealing jig of a weight through which the contact area of an opening section in an upper jig and an upper electrode for a semiconductor device is reduced. CONSTITUTION:A sealing jig contains a lower jig 2 into which a leadless type semiconductor device is inserted, an upper jig 1 with an opening section 7 in size of approximately one third of the area of an upper electrode 4 for the semiconductor device, and a weight 3 composed of a strut section inserted into the opening section 7 and a body section. The upper jig 1 organizing the sealing jig is brought to a high temperature at the same time as the lower jig 2 on sealing, the temperature of the semiconductor device is elevated, and a glass section 5 is melted. The weight 3 is brought into contact with the upper electrode 4 for the semiconductor device, and functions as the application of load to a pellet 8. Since the contact area of the opening section 7 in the upper jig 1 and the upper electrode 4 for the weight 3 is minimized at that time, the weight serves as the equalization of the temperature rise of the semiconductor device, the temperature gradient of the upper electrode 4 and a lower electrode 6. Accordingly, the contact state of the glass section 5 and the lower electrode 6 takes a shape that the inside is rounded slightly.
