Title: Magazine for rolled material
Inventor: NAITO HIDEO
IPC: G03C3/00
Filed: 1987-04-15
Abstract: PURPOSE:To prevent generation of flaws in a rolled material by providing deflecting parts to the hub bottom parts of side plates and providing detaining parts which freely releasably detain a winding core by overhanging into the winding core to the deflecting parts so that the winding core is detained and released to an from the deflecting parts in the deflecting direction thereof. CONSTITUTION:The side plates 2 have the deflecting parts 6 in the hub 5 bottom part and the deflecting parts 6 have the detaining parts 8 which freely releasably detain the winding core 3 by overhanging into the winding core 3. The winding core 3 is detained and released to and from the deflecting parts 6 in the deflecting direction thereof. More specifically, the detaining parts 8 overhanging into the winding core 3 from the deflecting parts 6 energize the inside surface of the winding core 3 wound with a rolled material 4 outward in the radial direction and fix the same to the hub 5 by the elastic force thereof, by which rotation of the material 4 by oscillation during transport and the consequent generation of loose winding are obviated. Galling of the magazine and the rolled material or the rolled materials against each other by the loose winding is thereby prevented.

Title: Surface light emission device
Inventor: FUJIGAMI MAKOTO
IPC: G02F1/13357
Filed: 1995-04-17
Abstract: PURPOSE: To simplify the manufacturing process and lower the cost, and obtain high front luminance without any luminance unevenness by specifying the constitution of the medium layers of a light guide plate. CONSTITUTION: The light guide plate 1 consists of the medium layers 4 and 5 which differ in refractive index. Those medium layers 4 and 5 are laminated alternately in parallel at a tilt angle θ of 20-70 deg., e.g. 45 deg. to the surface (light projection surface) of the light guide plate 1. Then the thickness D of the medium layers 4 and 5 is decreased in geometric sequence with the distance from a fluorescent lamp. Light incident on the light guide plate 1 is reflected by the boundary surface between the different medium layers and projected efficiently to the front direction of a user. Consequently, high front luminance is obtained. Further, the medium layers are made thicker with the distance from the light source, so the quantity of projection light to the front of the user is made uniform.  Consequently, luminance unevenness is reduced to obtain uniform lightness over the entire surface.

IPC: F01D5/14
Filed: 1980-07-07
Abstract: PURPOSE: To reduce profile loss of stationary vanes and additional loss of moving vanes by setting properly chord length of the stationary vane and axial distance between the stationary and moving vanes with respect to reach position in the longitudinal direction of vane length.  
     CONSTITUTION: Chord length of stationary vanes 13 in a stage structure of an axial fluid machine is maximized in a plane B-B of the central portion in the longitudinal direction so that axial distance ΔZ between the stationary vane 13 and moving vane 14 becomes the minimum ΔZ o  in the plane B-B. The chord length of the stationary vane 13 becomes smaller as it approaches side walls 15 and 16 from the plane B-B and thus ΔZ becomes larger so that the axial distances between vanes become respectively ΔZ t , ΔZ h  in planes C-C, A-A close to side walls 15 and 16 at the vane end. Also, sectional shape 13A taken along line A-A and sectional shape 13B taken along line C-C respectively near the side walls 15, 16 are defined smaller than that 13B taken along line B-B of the stationary vane 13.

IPC: G08B21/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a function of displaying output corresponding to the amount of gas by providing a display function which continuously changes in correspondence with the output of a gas sensor or a plurality of lightening display functions. SOLUTION: A gas-sensitive element 1 is combined with a gassensitive element 2 with equal dependency on temperature and humidity and different gas sensitivity characteristics to offset each temperature-humidity dependency. By this, it is possible to reduce the effect of temperature and humidity and to display absolute values. The gas-sensitive elements 1 and 2 are arranged on the same substrate with a heater. The output of the gas-sensitive elements 1 and 2 is derived from upper electrode deriving parts 3 and 4 respectively, and the lower electrode deriving part 5 is in common use for the gas-sensitive elements 1 and 2. A liquid crystal display in which output levels change according to sensor output or an LED display in which a plurality of LEDs are lighted up according to output levels is used as a display.  In this way, it is possible to detect minute quantities of gas in the air such as cigarette smoke, various unpleasant smell, exhaust gases and to display their detected levels visually.

Title: Storage device
Inventor: OIDA SEIGO
IPC: G11C8/00
Filed: 1983-05-25
Abstract: PURPOSE:To eliminate the need to alter a storage controller side when a memory board is altered by providing a memory board selecting circuit consisting of adders and comparators in the memory board. CONSTITUTION:Comparators C11, C12, and C41-C44 compare input values of adders A11, A12, and A41-A44 with the high-order three bits (signal on address signal line 21) from an address register 20, and outputs selection signals 100 and 102 with logic ''1'' when the comparison results show coincidence. The memory board M41, however, outputs the OR signal of the outputs of the comparators C41-C44 as a selection signal 101. An address signal on a signal line 22 is inputted in parallel to each memory board, but the high-order two bits of the address signal of M41 are generated by an encoder 110 which encodes the outputs of the comparators C41-C44. Each memory board is accessed on the basis of the address signal (obtained by adding the output of the encoder 110 as the high-order two bits for M41) on the signal line 22 only when the incorporated comparator generates an output with logic ''1''.

Title: Controlling method of electrostrictive actuator for stm
Inventor: SUYAMA TATSUYUKI
IPC: G01B7/34
Filed: 1989-04-13
Abstract: PURPOSE:To reduce hysteresis in the displacement characteristic of an actuator by a method wherein the displacement is obtained by increasing/reducing a voltage centering round an applied voltage in the voltage-displacement characteristic of said actuator. CONSTITUTION:An electrostrictive material produces a displacement proportional to a square of a voltage. Therefore, the displacement is a quadratic function which is expressed at the ordinate, with a voltage being expressed at the abscissa. Since the displacement is saturated at a high voltage, it has a point of inflection at a specified voltage. If a voltage centering on the point of inflection is applied to the electrostrictive material, linearity of the voltage and displacement equivalent to that of a piezoelectric material can be gained. In other words, if a bias voltage is set at a position corresponding to a displacement point in the displacement curve, it becomes possible to use the electrostrictive material having the displacement characteristic of less hysteresis with the same operativity as the piezoelectric material.
