Title: Heat-conveying device
Inventor: SAWADA TAKASHI
IPC: F28D15/02
Filed: 1990-01-16
Abstract: PURPOSE:To maintain the pressure inside a hermetically sealed circuit above the ambient pressure, thereby prevent the outside air from generating into the circuit and prevent corrosion, by sealing a heat transfer medium having a boiling point higher than normal temperature and a noncondensable gas in the hermetically sealed circuit. CONSTITUTION:A heater 1 and a radiator 2 are connected to each other by a forward pipe 3 and a backward pipe 4 to constitute a loop form, hermetically sealed circuit. A volatile heat transfer medium 5 such as flon (e.g. R11 or R123) and water is sealed in the circuit as a heat transfer medium having a boiling point higher than normal temperature, and nitrogen 9 is sealed in the circuit as a noncondensable gas. At non-heating times, the heat transfer medium 5 in the heater 1 is present in a liquid state, whereas nitrogen 9 in the circuit is present in a gaseous state, whereby the pressure inside the circuit is maintained above the ambient pressure. It is thereby possible to prevent the penetration of the outside air, which would cause corrosion, to stabilize the distribution of the heat transfer medium 5 in this device, and to prevent an abnormal temperature rise from occurring in the heater 1.

Title: Fluid pressure cylinder device with brake of variable braking force
Inventor: SATO HIROSHI
IPC: F16D65/28
Filed: 1987-01-13
Abstract: PURPOSE:To alleviate a shock at the stopping of a piston and ensure the proper stopping thereof by locking the slidable displacement of the piston with a pressing force between a friction rotary disc and a non-rotary part, and providing a cylinder chamber for controlling even the slidable displacement speed of the piston. CONSTITUTION:In order to stop a piston under slidable displacement, the pressure of a pressure fluid fed to a cylinder chamber 21 is pertinently controlled, thereby adjusting a force for actuating a push piston 18 against the energized force of a spring 22 and increasing this force to a suitable magnitude. As a result, there occurs a suitable pressing force for causing slidable contact between a friction rotary disc 23 and non-rotary members (i.e. intermediate fixed member 16 and push piston 18), a braking force due to friction is added to the friction rotary disc 23 and the piston 5 displaces slidably under a deceleration condition. And when the piston 5 has reached the predetermined position, the pressure of the pressure fluid is again controlled and adjusted, thereby releasing the pushing force of the piston 5 and locking the piston 5 at the predetermined position without any shock, using the energized force of the spring 22.

Title: Picture reader
Inventor: HORIKAWA KAZUO
IPC: H04N1/113
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate the need for a photoelectric sensor with a wider dynamic range than required by obtaining a partial peak value of a picture signal sequentially in the case of obtaining the picture signal and controlling a photodetector sensitivity of the photoelectric sensor based on the peak value obtained sequentially. CONSTITUTION:Since a high voltage applied to a photo multiplier 24 is controlled in response to a peak value for each main scanning by a picture signal SL' via a low pass filter 28, the photo multiplier 24 as a photoelectric sensor has a dynamic range of, e.g. 3 digit order. Moreover, a picture signal SL outputted from a log amplifier 25 is corrected in response to the high voltage applied to the photo multiplier 24. Thus, it is not required to use a photoelectric sensor with a wider dynamic range than required value and the cost is reduced.

Abstract: PURPOSE:To enable an easy formation of a bump having sufficient bonding strength even when there are variations in the heights of the bumps by making it possible to project the protruding part formed on the lower end of a pin from the opening of the lower end of a cylindrical body by the elastic deformation of an elastic body. CONSTITUTION:First of all, pressing downward an inner lead 18 by a lower end surface 11a of a cylindrical body 11b when forming a bump, since the distance from the center axis of the opening of the lower part of the cylindrical body 11b to its inner circumferential surface is so formed as to be at least shorter than the distance from the center of a hollow bump 19 to the end of the inner lead 18, the head of the inner lead 18 can be restrained by the cylindrical body 11b. Further, pushing a punch into the inner lead 18, an elastic body 15 is shrunk and a protruding part 13 of the head of a pin 12 is pushed into the inner lead 18 in a state that the end of the inner lead 18 is restrained. Furthermore, when detaching the punch, the pin 12 can be detached easily from the hollow bump 19 too, not deforming the inner lead 18. Thereby, even when there are variations in the heights of the bumps, the bonding to the bump is possible with a satisfactory bonding strength, and the bump of a hollow structure can be formed easily, not deforming the inner lead 18.
