Title: Finely moving device
Inventor: HARA ATSUSHI
IPC: H01L41/09
Filed: 1984-04-04
Abstract: PURPOSE:To suppress a vibration with a simple and inexpensive construction by forming a device body housing for storing and holding piezoelectric element group of a ferrite composite material. CONSTITUTION:A movable unit 3 is composed of a piezoelectric stretchable element 4 which axially stretches and contracts of a shaft 1 and a pair of front and rear piezoelectric clamping elements 5, 6 which stretches and contracts in a direction perpendicular to the stretching and contracting directions of the element 4. The shaft 1 is press-fitted fixedly to the hole 7a of a coupling member 7. A pair of coupling members 8, 9 couple and hold the both ends of the element 4, and are bonded fixedly to the elements 5, 6 integrally as the unit 3. A voltage is alternately applied to the elements 4-6 to telescope the shaft 1 integral with the unit 3 in the axial direction. In this case, a housing 2 for storing and holding the unit 3 and the like is formed of a ferrite composite material. Thus, since the damping characteristic is high and the impact vibration attenuating characteristic is excellent, the vibration absorbing effect can be enhanced.

Title: Semiconductor memory device
Inventor: YAMAMOTO MASAHIRO
IPC: G06F12/02
Filed: 1987-03-20
Abstract: PURPOSE:To set a memory area to a required minimum size by providing plural data each of which corresponds to a part of an address space and allocating plural data to pages at the time of switching them on demand and providing a selecting circuit which address a page to read out desired data. CONSTITUTION:For example, in case of read of a memory area P0, (0, 0, 0) is preliminarily inputted by read data O0-O2 to latch this information in latch circuits 6 if the page address of P0 is 0, and the selecting circuit selects Q0 to designate the memory area P0 because d0-d2 are 0 together. Thus, if one of memory areas P0-P7 where desired data is stored is preliminarily set, the same data is always read out from address space 0-3FFF though the same address is used for read when viewed from the CPU side; and plural kinds of data can be read out from address space 4,000-7FFF by switching.

Title: Gear type transmission
Inventor: HORI YOSHIAKI
IPC: F16H63/34
Filed: 1988-03-19
Abstract: PURPOSE:To prevent application of excessive torque to a speed change gear by maintaining a gear shift mechanism in non-transmission condition when a torque transmission/non-transmission condition selecting mechanism selects the non-transmission conditions in such a case that an input shaft or output shaft revolution number satisfies specific conditions. CONSTITUTION:When the number of revolutions of a counter shaft 1 or an output shaft 10 transmitted through a governer drive gear 30, that is an engine speed increases to or above a specified level, a governer weight 28 pushes a guide shaft 12 upwards. When a shift drum 13 is at a neutral position at this time, a stopper pin 18a ascends/descends together with the shaft 12, and engages with a branch groove of a second guide groove 16 to prohibit the rotation of the drum 13. As a result, gear change does not work, and non-transmission conditions under which the torque of the input shaft is not transmitted to the shaft 10 are retained. It is thus possible to prevent application of excessive torque to a speed change gear without using a torque limiter.

     CONSTITUTION: A constant voltage circuit 608 supplies a constant voltage lower than the voltage of a battery 800 to a drive circuit 609 for a DC motor 301 operating a throttle valve 201 of a carburetor or the like. The supplied voltage can be switched to a higher voltage through a switching circuit 607. Both the switching circuit 607 and the driving circuit 609 supply, temporarily at the time of starting the engine, a voltage higher than the voltage of the driving circuit 609 through a timing circuit 610 for starting and at the same time it drives the DC motor 301 to open the throttle valve 201. The timing circuit 610 is so constituted that the lower the engine temperature, the larger it is operated in cooperation with a temperature detecting means 400.

Title: Formation of reflecting mirror
Inventor: YAMADA AKIRA
IPC: G02B5/08
Filed: 1990-03-16
Abstract: PURPOSE:To obtain a reflecting surface adequate as a reflecting mirror for X-rays, etc., by forming an intermediate layer by vapor deposition on a substrate consisting of an insulator and forming an Au film by vapor deposition on this intermediate layer in succession thereto. CONSTITUTION:Glass is used as the insulating substrate 2 and Mo of a high melting material is used as the intermediate layer 1a. The Mo is put into a crucible 4 and after the inside of a vacuum chamber 9 is evacuated to about 10<-6> Torr by a discharge system 6, the Mo is heated up to 2500 to 3000 deg.C by a heating source 5 to evaporate the Mo. The film of the Mo is thus deposited by evaporation on the substrate 2 while the film thickness thereof is monitored from a change in electric resistance by a film thickness monitor 18. Although the film has an island structure in the initial period of the vapor deposition, the film becomes continuous at 30Angstrom  film thickness when the vapor deposition of the Mo is further progressed. The film thickness is measured by the film thickness monitor 18 at this time and the surface minimizing the ruggedness of the surface is obtd. The Au film 1 is then formed while the film thickness is measured by a monitor means in the same manner. The formation of the Au film 1 is executed by using a cluster ion beam method, applying an electron shower to the Au clusters and accelerating the Cu cluster ions by an acceleration electrode. The film is formed to the film thickness smaller than by the conventional vacuum vapor deposition method.

Filed: 1989-03-20
Abstract: PURPOSE:To make phosphors possible to emit luminescence with uniform luminance by putting three color-emitting phosphors in relative to a plurality of linear surface conductive electron discharging devices respectively and altering the driving voltages or the shapes of electron discharging parts according to the luminescent efficiency. CONSTITUTION:The title apparatus is composed with three lines of surface conductive electron discharging devices where one line contains 6 devices so as not to overlap their luminescent parts 7 of the devices and electron discharging parts 5 are so arranged to as be parallel each other as well as to electrodes 1, 2. Then, red-, green, and blue-emitting phosphors are so put on the devices solely while keeping the same distance as that between the devices of the multi- device as to make the arrangement of the phosphors in one line different from other lines. Since the luminescent efficiency of each different color light-emitting phosphor is different, driving voltage to be applied to each line should be changed and current value of electron beam should be modulated to obtain the same luminance. Owing to the oval shape of the luminescent parts in this structure, picture elements of the three colors can be made to be almost square and high density can be achieved.

IPC: D06B1/02
Filed: 1988-03-18
Abstract: PURPOSE:To accomplish a random discharge treatment easily as desired, without impairing the textile, without the need for using any chemical, by projecting a highly pressurized liquid on the surface of a textile (jeans). CONSTITUTION:A highly pressurized liquid 0.5MPa-100MPa in pressure is projected, via a nozzle, on the surface of a textile consisting mainly of cotton yarns such as jeans, thus accomplishing the objective discharge. In this case, manipulation of the projecting pattern for said pressurized liquid such as linear beam type, flat shape or nozzle movement as needed, enables a variety of patterns to be readily manifested. High-pressure fluid projection on a textile with its back surface provided with a uneven-surfaced backing member or punched member enable a discharge of varying denseness or patterns as would be the case with embossing process to be readily manifested. According to the above process, pollution-free treatment will be accomplished because of using no chemical.
