Title: Radiating device and semiconductor device using same
Inventor: NAGAOKA MINEO
IPC: H01L23/467
Filed: 1992-09-17
Abstract: PURPOSE:To improve radiating effect by the stirring of air around a radiating fin that is caused by vibrating the radiating fin by means of ultrasonic waves emitted from the source of ultrasonic waves. CONSTITUTION:A radiator 1 is made of a piezoelectric ceramic material having a superior thermal conductivity, and radiating fins 2 are made at given intervals in the form of a plate. An LSI chip 3 is thermally in contact with the rear surface of the radiator 1. An oscillation power source 4 generates an alternating voltage having a frequency which matches with the natural frequency determined by the intervals and material of the radiating fins 2, and this alternating voltage is supplied to the radiator 1. When the alternating voltage is supplied to the radiator 1, the radiator 1 oscillates itself, and causes micro vibrations. Then, the radiating fins 2 resonate, causing large vibrations. These vibrations stir air around the fins 2, and hence heat generated from the LSI chip 3 is efficiently discharged. Moreover, this renders an air-driving device such as a fan unnecessary, and hence the generation of noise is suppressed, and also the size of a radiating device can be reduced.

Title: Fuel injection system for internal combustion engine
Inventor: YAMAZAKI HIROBUMI
IPC: F02D41/06
Filed: 1988-09-30
Abstract: PURPOSE:To make an air-fuel ratio controllable to the optimum value by making a fuel injection quantity being fed to an internal combustion engine so as to control it smaller when a fact that the engine is in a starting state is detected and throttle valve opening is large enough. CONSTITUTION:At time of steady driving of an internal combustion engine 1, a fuel injection quantity is determined on the basis of intake pressure being detected by a pressure detector 13 and engine speed being detected by a crank angle detector 17. In contrast to this, when a starting state of the engine 1 is detected, first a fundamental injection quantity is found out of cooling water temperature being detected by a temperature detector 18 on the basis of the specified map value, and then a correction factor is found out of a temperature of intake air being detected by a temperature detector 12 on the basis of the specified map value. In succession, another correction factor is found out of throttle valve opening being detected by a throttle valve opening detector 16 on the basis of the specified map value, thus a fundamental injection quantity is compensated by these correction factors.

Title: Hydraulic power transmission joint
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1991-09-27
Abstract: PURPOSE:To miniaturize and lighten the joint by changing the spool valve orifice opening area of a movale magnetic body by the movable magnetic body for generating attractive force according to the current of a solenoid, and a spring for generating load proportional to the displacement quantity. CONSTITUTION:When a current is not applied to a solenoid coil 27, a movable magnetic body 28 does not generate magnetic attractive force, nor is generated the load of a spring 29, and an orifice 21 is fully opened so that oil flows to the orifice 21 and an intake passage 11 from a high pressure chamber 15 to place a torque characteristic in the free state. When the current is made larger and rotational difference is generated between a cam 2 and a rotor 3 in this state, a plunger supplies oil in a plunger chamber 5 into the intake passage 11, and the oil pressure of the plunger chamber 5 rises by the resistance of the orifice 21 to transmit torque between the cam 2 and the rotor 3. When the current is made further larger and the load of the spring 29 reaches the specified value, the movable magnetic body 28 comes in contact with a valve 9, so that the torque characteristic is placed into the lock state. The orifice opening can be thus continuously variable while miniaturizing and lightening.

Title: Measuring method for refractive index
Inventor: YATAKI MASAMICHI
IPC: G01N21/41
Filed: 1994-09-16
Abstract: PURPOSE: To decrease the mixing rate of errors to enable measuring an evaluated amount with high reliability by originating a simple rectilinear calibration curve by use of a branching ratio to which a bias has been added. CONSTITUTION: When a predetermined bias value (b) (0<(b)<1) (e.g. about 5% of the total amount measured) is added to a transmitted light output P1 and to a branching light output P2 which are transmitted respectively from optical fibers f1 , f2 and measured in advance by use of a calibration sample, and a branching ratio R represented by an equation R=10.log  (P1 +bP1 )/(P2 + bP2 )} is computed, a spectral branching ratio characteristic becomes triangular and an inclined part which constitutes a curve becomes rectilinear. When a calibration curve showing a correlation with an evaluated amount (e.g. the oil content of wax) is originated by use of the branching ratio R, it is made rectilinear so that few errors are allowed into it.  Therefore, when the evaluated amount of a subject S to be measured is calculated on the basis of the calibration curve, estimation of the evaluated amount and extraction of the results of judgment can be performed automatically and highly reliable measurements can be made promptly.

Abstract: PURPOSE:To enable a user to optionally produce or correct a display data file by designating an optional item display position on a displayed screen and then supplying the character data through a touch panel. CONSTITUTION:When a contact is given to an item display position on a touch panel 2 corresponding to the data item to be supplied or corrected while a display device 1 is displaying a text page, a screen/write control circuit 100 designates an address corresponding to a data item of a text page to undergo the self-writing at a memory 3. The contents of the memory 3 are transferred to a memory 32. The contents of the memory 32 are sent to a pattern generator 106 and displayed to the device 1 after pattern conversion. When an input of characters is desired for input of the correction data, a key switch 4 for table of contents is turned on. Then the desired characters are designated on the panel 2, and a contact is given to an input data area of the panel 2. Thus the production or corrections are newly carried out for the designated data item of the designated text page.

Title: Optical coordinate transforming device
Inventor: MITSUOKA YASUYUKI
IPC: G02B27/46
Filed: 1989-09-25
Abstract: PURPOSE:To eliminate the variance in the intensity of a coordinate transformed image and to perform accurate pattern recognition and measurement by subjecting the intensity distribution of the coordinate transformed image to the binarization processing to display it on a second space optical modulator. CONSTITUTION:The luminuous flux transmitted through a beam splitter 3 is thrown to a first space optical modulator 4, where an input image is written, to convert the input image to a coherent image. The coherent image is transmit ted through a coordinate transforming filter 5 and is subjected to Fourier trans formation by a Fourier transforming lens 6 and is thrown to a second space optical modulator 7. Since the second space optical modulator 7 is an optical write type liquid crystal light valve and ferroelectric liquid crystal having a distinct bistability between the light transmittance or the light reflectivity and the applied voltage is used as a liquid crystal layer, the image into which the coordinate transformed image of the input image is binarized is obtained. Thus, accurate pattern recognition and measurement free from the variance in the intensity of the coordinate trans-formed image are performed.

Title: Metal multilayer film having positive magnetization temperature coefficient
Inventor: SAKAKIMA HIROSHI
IPC: H01F10/10
Filed: 1984-11-26
Abstract: PURPOSE:To obtain a ferromagnetic substance having a positive magnetization temperature coefficient by alternatively laminating layers containing Co as the main component and layers containing Mn as the main component, and making the thickness of the Co layers 50Angstrom  or less. CONSTITUTION:On a glass of Si substrate which was sufficiently cooled in ultra-high vacuum of 10<-9>Torr, Co layers (thickness: TCo) and Mn layers (thickness: tMn) are alternatively laminated with inter-layer diffusion being prevented. For a constant ferromagnetic resonance frequency, magnetization of this multilayer film begins to decrease along with reduction of the temperature T when the temperature T is equal to the transformation temperature T5 (marked by an arrow) or less. Namely, the temperature coefficient alpha>0. Further, for TCo>50Angstrom , there is no Tt. Shifting to the high temperature side as TCo decreases (A E), magnetization is in substantially direct proportion to T for TCo<=12Angstrom , and in proportion to T to the 3/2 for TCo>18Angstrom . Such a multilayer film showing alpha>0 is not found except this, and a film having power dependency of transformation temperature Tt and temperature T which can be artificially adjusted can be formed by alternatively laminating Co and Mn to predetermined thicknesses.

Title: Logical gate circuit
Inventor: TSUJI TSUZUMI
IPC: H03K19/0952
Filed: 1993-10-05
Abstract: PURPOSE:To reduce the L(low) level of output and to secure a satisfactory noise margin by connecting a voltage clamping element between a ground terminal and one of input terminals that has the voltage of an unnecessarily H(high) level. CONSTITUTION:When the voltage of H levels are supplied to both input terminals IN1 and IN2, both E-FET1 and E-FET2 are turned on. Then the current supplied from a D-FET1 serving as a constant current source flows through the E-FET1 and E-FET2 and an output terminal OUT is set at an L level. At the same time, the anode A and the cathode K of a diode D1 are connected to an input terminal IN1 and a ground terminal GND respectively. The diode D1 functions to keep the voltage of an H level of the terminal IN1 under voltage Vgsh (where output power IOUT is equal to gate current Vg). That is, the most of the output current IOUT flowing to the gate of the E-FET1 flows to the diode D1 so that the increase of the drain-source voltage VDS2NO can be suppressed for the E-FET2.
