Inventor: MATSUI TAKAYUKI
IPC: F25B9/14
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To improve refrigerating efficiency by a method wherein a cold accumulator connected alternately in series and a cold accumulator at one end inside a cold head are connected to a pressure fluctuation mechanism on the cold accumulator side and the operation timings of phase regulating mechanisms on the pulse pipe side are respectively independently controlled.

Title: Manufacture of semiconductor device
Inventor: HAJIKANO YOSHIICHI
IPC: H01L29/78
Filed: 1985-04-05
Abstract: PURPOSE:To reduce the lowering of an output level due to the dispersion of charges without increasing the number of manufacturing processes by forming a wiring connecting a transfer-gate MISFET and a driving circuit by a high-concentration diffusion layer. CONSTITUTION:A wiring l1 connecting a transfer-gate MISFETM4 and a pre- stage circuit (a source in an MISFETM1 for supplying a power supply and a drain in an MISFETM2 for driving) is shaped by a high-concentration diffusion layer in order to increase the floating capacitance C1 of the wiring l1. On the other hand, a wiring l2 connecting the transfer-gate MISFETM4 and a post- stage circuit (a gate in an MISFETM6 for driving) is formed by normal polysilicon, etc. in order to reduce the floating capacitance C2 of the wiring l2. The same applies to a transfer-gate MISFETM8 at the next stage. Accordingly, the capacitance of the wiring l1 is represented by a capacitance by a depletion layer induced by applying reverse bias voltage in a P-N junction between a semiconductor base body and the high-concentration diffusion layer.

Abstract: PURPOSE: To alarm the service limit of the base of an antiabrasive hose securely and easily, by providing a groove or a hole with a specific depth to be the service limit to at least one place on the exposing part of the base unit other than a nipple part. CONSTITUTION: Since a groove or a hole 2 with a specific depth D2 to be the service limit is provided to at least one position of the exposing part of a base unit other than a nipple part 7 of the base unit 1, the inner side and the outer side of the base unit are penetrated at the groove or the hole when the part is abraded from the thickness D1 at the new condition to the thickness D2 at the service limit by transporting a fluid inside the base unit, and the service limit from leaking the transported fluid from the position is alarmed accurately without using an other measuring apparatus. And the influence to the strength of the whole body of the base unit by providing such a groove or hole, in this case, is almost negligible because the section area of the groove or the hole is very small.

Title: Production of channel type optical wave guide
Inventor: ENOMOTO AKIRA
IPC: G02B6/13
Filed: 1989-03-27
Abstract: PURPOSE:To obtain the channel type optical wave guide having the high efficiency of confining light by forming a hollow groove which has the shape of an optical wave guide and the inside surface of which has a specular state on a substrate surface, forming the parts exclusive of this hollow groove to a rough surface state and carrying out an operation to grow a crystal film. CONSTITUTION:A photoresist film is formed on the substrate in the part thereof to be formed with the optical wave guide by a resist pattern and a metallic film is formed by a sputtering, etc., over the entire surface of the substrate; thereafter, the metallic film on the resist pattern is removed together with the resist to expose only the part to be formed with the optical wave guide. This part is subjected to an ion beam etching or the like to form the hollow groove the inside surface of which has the specular state. The parts exclusive of the hollow groove of the substrate are then made into the rough surface state by a mechanical treatment or the like. The good quality crystal film is grown in the hollow groove of the specular state and fills the inside of the hollow groove when the entire surface of the substrate is subjected to crystal growth. However, the film is not grown in the parts of the rough surface state or even if the film is grown therein, the film is inferior and can be easily removed by a weak etching treatment and, therefore, the optical wave guide is easily formed on the substrate. The channel type optical wave guide having the high efficiency of confining light is easily and efficiently produced in this way.
