Title: Cooling device
Inventor: NOGUCHI YASUTAKA
IPC: F28D15/02
Filed: 1983-03-25
Abstract: PURPOSE:To provide a cooling device which is most suitable for cooling of a high-density heat generative part in an electronic equipment or an electronic element, utilizing the heat of vaporization. CONSTITUTION:When a driving flange 9 is rotated by a motor 12, a parmanent magnet 11 fixed to the driving flange 9 is rotated along the outer wall of a sealed container 1, and its rotating force is transmitted to a driven shaft 7 to which a parmanent magnet piece 8 is fixed. By this driving force, a coil 6 fixed to the driven shaft 7 can be rotated. An operating fluid being sealed in a gap 10 absorbs heat and vaporises when heat is applied to a heating part 4 at one end of a sealed container 1 in the state that the coil 6 is rotated. The vapor flows into a condensing part 5 where the pressure is low, passing through a vapor passage 3. The vaporized operating fluid being cooled by an open air through the sealed container 1 condenses and adheres to the coil 6 in the condensing part, but it is again moved into the heating part 4 by the rotating coil 6. By the above-mentioned continuous pumping operations, a transfer action of high-density heat can be performed stably from the heating part to the condensing part, so that the cooling device can stably cool high-density heat generator such as a LSI or a semiconductor lazer.

Filed: 1989-02-28
Abstract: PURPOSE:To decrease effect of a pattern edge as well as that of a pattern and obtain an integrated circuit device equipped with a transistor which holds uniform characteristics and is superior in breakdown strength performance by forming a protective film of a prescribed shape on a diffusion layer of the surface of a semiconductor substrate and removing the diffusion layer selectively by the use of the protective film as a mask. CONSTITUTION:An N<+> type silica film coating film 2 is formed on a P-type silicon substrate 1 and impurities in the coating film 2 is allowed to diffuse in the substrate 1 so as to form an N<+> type diffusion layer 3. Then a nitride film 7 is formed wholly as a protective film. After that, the nitride film 7 located at a region other than the region where a buried diffusion region is expected to be formed by dry-etching is removed. Then wet-etching is performed by the use of the nitride film that is still in existence as a mask and the silica film coating film 2 is removed selectively. Then an opening 9 is provided so that the diffusion layer 3 at a part other than a region where a buried diffusion region is expected to be formed is exposed. In this way, effects of a pattern edge as well as a pattern are suppressed and an integrated circuit device equipped with a bipolar transistor which holds uniform characteristics and is superior in breakdown strength performance is obtained.

Title: Semiconductor integrated circuit
Inventor: KURASHIMA YASUMI
IPC: H01L27/04
Filed: 1990-03-02
Abstract: PURPOSE:To avoid a drop in a margin against a logic threshold value by a method wherein a potential supply position of a bus line of a low-potential-side power supply and a connecting position of a constant-voltage generation circuit connected to said bus line are set in such a way that a potential drop and a potential rise by an interconnection has a relationship which is offset mutually. CONSTITUTION:Constant-voltage generation circuits 4 are connected to both ends of a low-potential-side bus line 1; the center of the bus line 1 is decided as a potential supply position of a low-potential-side power supply; then, a power-supply potential is supplied. As a result, potentials at a constant voltage for control use on the constant-current source side and at a power-supply bus line become highest at both ends and lowest in the center of the bus line by a potential drop and a potential rise by an interconnection. Consequently, the potential drop by the interconnection of a constant voltage for control use and the potential rise of the bus line are offset mutually, and the position dependence of a constant current is reduced. Thereby, a drop in a margin against a logic threshold value is not caused at a semiconductor integrated circuit of a bipolar transistor type.

Title: Iron club set
Inventor: OBARA TOSHIO
IPC: A63B102/32
Filed: 1989-03-01
Abstract: PURPOSE:To permit an amount of back spin of each club to be adjusted by increasing sequentially the width and depth of each groove on a face surface or increasing sequentially the inclination of side face of each groove as the count of the club is enlarged, or employing the combination of at least these two means to increase friction to a ball. CONSTITUTION:The width and depth of groove on the face surface or the indication of side face of each club in an iron club 10 set are increased sequentially as the count of the club is enlarged. As the width W, depth D and slant angle A of side face are increased, the groove 12 on the face surface 11 of club increases friction to a ball and an amount of back spin. Thus, the club of small count in the iron club set provides the small back spin and the club of large count provides the large back spin.

Abstract: PURPOSE:To improve the steering feeling by installing an actuator which applies an auxiliary steering force through the control according to the prescribed function of a steering force and applying an auxiliary righting force for the steering angle through the control according to the steering angle. CONSTITUTION:When a handle 1 is operated to apply a torque onto a handle shaft 2, a torque signal (tau) is outputted from a torque sensor 6. Said signal (tau) is inputted into a controller 11, which drives an electric motor 7 to apply an auxiliary steering force. The controller 11 controls the electric motor 7 in high speed so that the driving force of the motor 7 is reduced or the drive of the motor 7 is brought into stop according to a car-speed signal V. Further, when the torque signal (tau) reduces less than a prescribed value on releasing steering, the controller 11 controls the motor 7 so that the auxiliary righting force is generated in the opposite direction to the auxiliary steering force by the aid of the steering signal (theta) supplied from a steering-angle sensor 10.

Title: Method for measuring electrostatic capacity
Inventor: MIKI HIDETANE
IPC: H01L21/66
Filed: 1985-03-13
Abstract: PURPOSE:To measure the very small capacity in a pellet, by erecting needles on the wirings at both terminals of the minute capacitor of a pellet state in a semiconductor apparatus and connecting the same to a parallel resonance circuit in parallel. CONSTITUTION:A signal source 1 is connected to a parallel resonance circuit 2 through a resistor 3 and the output levels at both terminals of the circuit 2 are measured by a detector 7. If the relation between the frequency omega and output voltage V0 of the signal source 1 and the coil L and capacity C0 of the circuit 2 is set to omega<2>=1/LC0, the voltage level between both terminals of the circuit when a minute capacitor 6 is not connected is measured as the voltage level V0 shown by a drawing by the detector 7. Next, when needles are errected on the wirings of both terminals of the minute capacitor 6 in a pellet and connected to the circuit 2 in parallel, the oscillation frequency of the circuit 2 changes. When the value of the capacitor 6 is set to DELTAC, the relation between the voltage level V and capacity C between both terminals of the circuit 2 comes to one shown by the drawing and, therefore, if the voltage level V is preliminarily measured in a state having no capacitor 6, the minute capacity in the pellet is measured from the V-value of the detector 7.
