Abstract: PURPOSE:To reduce the manufacturing cost of the title radiator by a method wherein the radiator is constituted of a square flat plate heat receiving unit, in which one parts of respective spiral rings of a loop type fine tube container which forms circular or rectangular coil are bonded to neighboring spiral rings sequentially, and the group of heat radiating fins, constituted of remaining spiral rings. CONSTITUTION:When a radiator is formed, fine tube 1 for the container of a loop type fine tube heat pipe is wound around a core member 7 having a predetermined sectional configuration. Under a condition as it is, one parts of respective spiral rings which form a coil are bonded through a predetermined bonding means so that neighboring similar parts of respective neighboring spiral rings are bonded sequentially to each other and the bonded parts form a square plate surface 2 as a whole. Subsequently, the square plate surface 2 is formed so as to be a smooth flat plate while the core member 7 is removed before or after forming the flat plate to obtain the configuration of the fine tube coil 1 which is easily ventilated. The heat radiating unit has a large radius of curvature and, therefore, shaping is easy and it can be deformed in accordance with the size of a heat generating element 3. On the other hand, the pressure loss of operating liquid is reduced and, therefore, the heat radiating capacity of the radiator is improved. A connecting tube 6 is made by connecting both terminal ends of the fine tube container so as to constitute a loop.

Title: Multiplier
IPC: G06F7/52
Filed: 1992-03-17
Abstract: PURPOSE:To reduce the effective time needed for the normalization and the rounding and to carry out the multiplication at a high speed by carrying out the normalization and the rounding processing which has been carried out so far after the addition of an intermediate product in parallel to the addition. CONSTITUTION:An intermediate product adder 105 outputs 119, i.e., the result of addition of the high order parts 140 and 141 of the output of a partial product adder 101, 108 obtained by adding 119 by one and 117 obtained by adding 118 by one. Furthermore the adder 105 gives the rounding position candidates 125 and 126 to a condition deciding circuit 104. A rounding value calculation circuit 103 assumes the information necessary for the rounding and outputs two types of bits 122 necessary for the rounding and four types of rounding value 120 and 121 from the lower order parts 115 and 116. A carry foresight circuit 102 outputs the information 123 necessary for the rounding and a carry 124. Then, the circuit 104 outputs a signal 127 to select the addition results 117-119 out of the information 120-126. In such a constitution, the time required for a series of processings of the normalization and the rounding can be reduced from the addition of an intermediate product.

Title: Signal amplifying circuit
Inventor: SASAKI ATSUSHI
IPC: H03G5/16
Filed: 1980-05-09
Abstract: PURPOSE:To emphasize the level of the low-pitched sound range and protect a speaker from a heat destruction, by using a circuit that amplifiers several tens of waves at the rise part of a speaker input signal in order to compensate for the shortage of level at the low-pitched sound range of a speaker system. CONSTITUTION:The output of a music signal source 1 such as a player or the like is supplied via a control amplifier 2 to an HPF5 which cuts off the same frequency as the LPFs 3 and 4 that cut off the maximum frequency of the frequency band that is going to amplify the rise amplitude. The output of the LPF3 receives an extraction 6 for its envelope wave signal and then an extraction 7 for the control signal. This output signal 17 is supplied to a voltage control amplifying circuit 8. On the other hand, the output of the LPF4 is supplied to the circuit 8 and then amplified like (b) in proportion to the supplied voltage and for a period during which the signal 17 is supplied. The output signal 18 thus obtained is added 9 with the output of the HPF5 to drive a speaker 20 via a power amplifier 10. Thus the low-pitched sound feeling is increased by an amplifying action in a comparatively short time.

Title: Optical type distance and inclination measuring apparatus
Inventor: IKEGAKI TETSUO
IPC: G01B11/26
Filed: 1986-03-20
Abstract: PURPOSE:To measure the angle of inclination of an object to be measured and a vertical movement distance from a reference position at a high accuracy, by gauging a distance of individual irradiation spots as function of only the angle of inclination of the object being measured. CONSTITUTION:This optical type distance and inclination measuring apparatus divides in two a reflected luminous flux 10 from an object 3 to be measured. As a result, an angle psi of inclination of the object 3 being measured from a distance S of irradiation spots X1 and X2 as function of only the angle psiof inclination of the object 3 being measured and a vertical movement (c) from a reference position can be determined simultaneously by computation. In this case, as this operation requires only one incident luminous flux 9, the angle psiof inclination and the vertical movement (c) at the same measuring point can be determined simultaneously thereby assuring a high measuring accuracy. For example, when the size of each pixel of a CCD composing light receivers 7 and 8 is 14mum, the available measuring accuracy is 4.7mum for the vertical moving distance and 0.004 degree for the angle of inclination.

Title: Thermally drive type motor
Inventor: YANO KATSUAKI
IPC: H02N10/00
Filed: 1980-05-08
Abstract: PURPOSE:To smoothly operate a thermally drive type motor by providing an actuator made of a plurality of magnetic adjusters in a magnetic field space formed of magnetic poles, mainly heating the position displaced from the magnetic center and preliminarily heating the position toward the center side. CONSTITUTION:A rotary disk 4 in which an actuator 3 made of magnetic adjusters A-I which abruptly reduce the magnetic permeability when the temperature reaches Curie point is arranged in the magnetic field space 2 of a permanent magnet 1 or the like, and a nozzle 8 for injecting blast or fire is obliquely arranged under the position displaced from the magnetic center of the pole 1. Accordingly, the blast of the nozzle 8 serves to heat the B part most strongly to displace the magnetic field 2 to thus move the disk 4 toward an X-direction, and since it also preliminarily heats the C and D parts displaced toward the magnetic center side, it can accelerate the arrival of the temperature to higher than the Curie point at the main heating time, thereby smoothly performing the rotary operation.

Abstract: PURPOSE:To equalize the deposition rate of a metal on plating, and to improve the dimensional accuracy of a bump by forming an electrode wiring gauze consisting of a low resistance metal to the excess section of a transparent conductive film layer in a substrate and reducing the equivalent resistance of the transparent conductive film layer. CONSTITUTION:A transparent conductive film layer 8 is formed extending over the whole region of the main surface of a bump plating substrate 7, and an electrode metallic wiring mesh 11 consisting of a low resistance metallic material is formed while surrounding the outer circumferential regions of opening regions 12 for bump forming plating. The whole surface is coated with an insulating protective film layer 9 such as an SiO2 film, and opening sections 10 are shaped. When a cathode for a power supply for plating is connected to an electrode section 13 for an external connecting wire and the electrode section 13 is treated through an electroplating method, plating deposits while using the transparent conductive film layers 8 exposed to the opening sections 10 as cathodes and bumps are formed. Since the exclusive wiring electrodes 11 composed of the low resistance metallic layers are shaped, the conditions of plating in the whole sections on the substrate are equalized, and the dispersion of the height of the bumps due to the difference of the speed of plating is inhibited.
