Title: Production of composite in microgravitational field
Inventor: ODAWARA OSAMU
IPC: C04B35/65
Filed: 1988-02-25
Abstract: PURPOSE:To provide the title production process so designed that a reaction chamber is packed with a specific mixture followed by ignition and dropping said mixture, hereby creating a microgravitational field equivalent to the space for a short time and producing a high- temperature condition without the need for an electric furnace or the like, thus enabling a homogeneous molten composite to be easily and economically obtained. CONSTITUTION:Firstly, an initial mixture to be ignited is prepared by homogeneously mixing (A) oxide(s) of metal(s) belonging to the fourth-sixth periods in the periodic table, (B) a reducing agent selected from Al, Mg, Zr, and Ti and (C) a non-metal selected from C, B and Si or an oxide therefrom (e.g., B2O3, SiO2). Thence, a mixture 5 containing this initial mixture is packed in a reaction chamber 4 and set on a reaction chamber-loading-and- unloading jig 3 at the upper end of a falling column 2 ca. 100m in height followed by introducing an ignition means 1 made of wire filament into said mixture to effect heating and ignition followed by dropping the reaction chamber 4. The resultant self exothermic reaction in a microgravitational field created during the dropping produces a high-temperature condition of e.g., >=3,000 deg.K to effect melting and homogeneous mixing to form a composite of homogeneous dispersion according to the initial packing distribution. Said composite is then reduced in speed by a heat-resistant shock-absorbing net 6 and received into a cooling medium 7, thus obtaining the objective composite free from interface debonding and so on.

Title: Solid-state image-pickup device, automatic focus adjustment device using it, and image-pickup system
Inventor: OKI MASAYUKI
IPC: G02B7/28
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To improve the transfer efficiency of a signal charge and to reduce cost by providing a substractor section between a horizontal CCD and a circulation CCD, subtracting a signal charge at a non-lighting from a signal charge at lighting and transferring the difference to the circulation CCD sequentially, so as to be accumulated therein. SOLUTION: For a solid-state image pickup device, a substractor section 60 is provided between a horizontal CCD 140 and a circulation CCD 70. A signal charge transferred to the horizontal CCD 140 is transferred to a substractor section 6, placed at a pre-stage of the circulation CCD 70. The substractor section 60 subtracts the signal charge at non-lighting from the signal charge at lighting and transfers sequentially only the signal charge after the subtraction processing to the CCD 70. The transferred signal charge only after the subtraction processing is circulated in the circulation CCD 70 and summed with a signal charge after succeeding subtraction transferred from the substractor section 60 for every circulation. The signal charge is amplified by repeating the operation and when the charges amount to a prescribed amount, the charges are transferred to a read section, in which a focus with respect to an object is specified.

Abstract: PURPOSE:To increase the degree of freedom for the control of the process control or the count control of a plant, by feeding a desired program to a volatile main storage device from a secondary storage device when the power supply is applied and then giving CPU control. CONSTITUTION:A CPU1 performs a prescribed operation based on a program stored in a main storage device 2 and then gives the control to the process via an input/output device 5. A floppy disk device 3 consists of a floppy disk (FDD) 3a and a power supply switch 3b. The FDD3a stores a program which runs in the normal operation mode, i.e., a program to be stored in the device 2. The contents of the device 2 are erased when the power supply of a programmable controller is turned off or interrupted. When the power supply is applied or recovered, the program of the FFD3a is transferred to the device 2. After this, the switch 3b is turned off. The CPU1 performs the control based on the program of the device 2. Thus the degree of freedom is increased for the control with an exchange of the FFD3a.

A controller 8 controls the output of a heater 7 so that a temperature, which is detected by the sensor 3, is kept constant and a temperature control is made possible with an accuracy of + or -1 deg.C. That is, as a feedback is applied using the heater 7 so that a detection temperature is kept constant and the surface temperature of the element 2 during operation can be measured, this surface temperature is controlled by the heater 7 at a constant level. As for the heater, it is desirable to form a Peltier element material, whose speed of responce to heating and cooling is fast, on the periphery of the device 1.

Title: Bulletproof panel, bulletproof panel equipment and bulletproof equipment
Inventor: TANOUE TOSHIAKI
IPC: F41H5/02
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a low cost and a light weight bulletproof panel, panel equipment, and bulletproof equipment which are simple in structure and moreover, excellent in interior design by providing a bulletproof board slantly to the surface in a box in which at least one external surface is a to-be-fired surface. SOLUTION: A bulletproof board 8 is set up inside a box 1 slantingly to a surface to be fired. The upper end and lower end of the bulletproof board 8 are bent horizontally, thereby preventing the bulletproof board 8 from moving unexpectedly inside a box main body 2. When a bullet is fired, the bullet is penetrated through a surface 2A of the box main body 2, a cover 3 or a surface 2C of the box main body 2 so that its kinematic energy may be reduced while a warhead may be smashed. Since the bulletproof board 8 is set up slantingly to the fired surface, the bullet is collided with the bulletproof board at an angle of cute incidence, the penetration force is reduced so that the bullet is rebounded and is left over in the box 1. Even when the bullet is penetrated through the bulletproof board 8, it strikes against the other box main body 3 or cover 3 so that the bullet may be rebounded.

Filed: 1991-03-07
Abstract: PURPOSE: To resolve problems caused by the application of a high voltage to a cathode and a grid by keeping an inner body part at high voltage to an outer body part, and forming no conductive connection between both body parts. CONSTITUTION: Direct electrical contact does not exist between any part of an inner body part 40 and flanges 44, 46, and an insulating dielectric material 52 is molded between them.

IPC: G03G15/00
Filed: 1995-03-01
Abstract: PURPOSE: To provide a drive mechanism capable of selectively driving a plurality of output drive members with a single input drive member. CONSTITUTION: A frame 100 having pawls 94, 95 is operated by a single solenoid 106 and spring 108 combination. During successive cycles of solenoid operation, a selected pawl engages with its mating ratchet gear 78 or 88 by action of the solenoid. This action, while the pawl is being engaged, prevents the selected gear from being rotated. The unselected pawl disengages its mating gear to permit it to rotate freely, thereby driving an output shaft connected with the gear.
