Title: Integrated socket wrench
Inventor: TAKANO YUKIO
IPC: B25B13/10
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce the number of socket wrench by integrating plural socket wrenches. SOLUTION: Eight kinds of socket wrench having the dimension at 8 mm, 9 mm, 10 mm, 12 mm, 14 mm, 17 mm, 19, mm, 21 mm and to be frequently used are integrally assembled with each other freely to be slid. In the case of using this assembly for a bolt and a nut at 8 mm and 9 mm, it can be used without sliding, and in the case of use for a bolt and a nut at 10 mm or more, for example at 14 mm, when a little force is applied while pushing the socket wrench to the bolt and nut, each socket wrench at 8 mm, 9 mm, 10 mm, 12 mm is moved backward by the height of a head of the bolt and the height of a head of the nut. With this movement, a socket wrench at 14 mm covers the bolt and nut, and the whole is rotated for fastening or loosening.

Title: Drive system for charge transfer element
Inventor: IWAZAWA MINEO
IPC: H04N5/335
Filed: 1978-09-06
Abstract: PURPOSE: To improve transfer efficiency by applying either electrode, a storage electrode or a transfer electrode, with a pulse falling in step.  
     CONSTITUTION: To transfer pulse input terminal 61, a transfer pulse voltage is supplied as much as one phase. This pulse voltage is supplied to pulse-width expanding circuit 62, thereby outputting from terminal 63 pulses with pulse width only the trailing edge of the transfer pulse expanded by an overlapping method. From terminal 64 of circuit 62, only pulses of the pulse-width expansion part are outputted. Those output pulses are inputted to one terminal of voltage regulator 65, and a direct-current voltage is to the other terminal 66. At output terminal 67 of regulator 65, a signal appears which has two voltage levels, VCP 1  and VCP 2 . When this output  is supplied to clock driver 68, driver 68 generates a signal of pulse waveform falling  by two steps from inputs 63 and 67 and supplies it to the transfer electrode of CCD. Consequently, the electrode transfer time of the fall part of the pulse can be set longer than a maximum time width where charge moves in the Si substrate.

Abstract: PROBLEM TO BE SOLVED: To shorten the time required for production of a state equation by calculating the state variable of an input variable and the partial derivative concerning an operation variable from a state variable and an input variable and generating a linear state equation and an output equation from the partial derivative. SOLUTION: When the operational elements corresponding to the state variable, operation variable and output variable of a state equation given from an input part 4 are designated to the block diagram data given from an input part 3, an automatic generation part 5 of the state equation traces a signal from the start points set at the operational elements corresponding to the state and output variables through the operational elements corresponding to the state and operation variables in the upstream direction. Thus, the part 5 calculates the state variable of an input variable and the partial derivative concerning the operation variable from the relevant state and output variables and then generates a linear state equation and an output equation from the partial derivative. As a result, the time required for production of the state equation can be extremely shortened.

Title: Shadow mask and its manufacture
Inventor: HIDESHIMA TAKAFUMI
IPC: H01J29/07
Filed: 1990-04-25
Abstract: PURPOSE:To pass electron beam sufficiently and at the same time to prevent holes from communicating each other by making holes in the front side almost elliptical and holes in the back side circular, and bringing the longitudinal direction of the front side holes into harmony with the proceeding direction of the electron beam. CONSTITUTION:While holes in the back side are circular, the shapes of holes 1 in the front side are almost elliptical in radial direction. The major axis of the almost elliptical holes 1 in the front side is brought into harmony with the center direction of a shadow mask. That is, the longitudinal direction of the front side holes 1 is brought into harmony with the proceeding direction of electron beam. Consequently, the roundness of the through holes is maintained and at the same time since unnecessary parts in conventional circular shapes in the front side are prevented from corroding, the whole of the mask becomes firm. As a result, the holes are prevented from communicating each other and at the same time electron beam is passed efficiently.
