Title: Data communication system
Inventor: KUMAKURA KAZUMASA
IPC: H04L1/16
Filed: 1978-11-27
Abstract: PURPOSE:To realize an ARQ system of the perfect full double system by installing the band elimination filter to eliminate the single frequency response signal which is sent back to the transmission side from the reception side and then carrying out only the data transfer via the band elimination filter. CONSTITUTION:The data is sent out from transmission side (a) via MODEM M and band elimination filter BF, and thus the frequency component of the affirmative answer character ACk signal is eliminated. As a result, no erroneous detection is given to the ACK signal frequency component. While at the reception side (b), the reception signal is supplied to MODEM M via BF, and thus the ACK signal generated from ACK signal generator circuit A of the reception side is eliminated. As a result, no bit error is caused to the reception data.

Abstract: PURPOSE:To make small the circuit resistance in a refrigerating cycle during room- heating operation and make also small the pressure difference between the high pressure side of a compressor and its low pressure side to make small the electric power input of the compressor and make it possible to reduce noises to a low level by connecting the discharge side of the compressor and outlet side of a coolant heater with a bypass circuit and opening and closing this circuit at a special timing. CONSTITUTION:A third bypass circuit which has a valve mechanism 13 is provided, and during room-heating valve mechanisms 8 and 13 are opened and valve mechanism 7 and 11 are closed. The valve mechanism 13 is constituted to open after the operation of a certain time and open once before restarting the operation. With this arrangement part of the flow of the coolant from the compressor 1 circulates from the high pressure side to the low pressure side. Now a volume of circulation required for the actual refrigerating cycle is adjusted by changing the circuit resistance of this circuit 14. Accordingly the coolant is bypassed from the high pressure side to the low pressure side of the compressor by the circuit 14 to reduce the difference between the high pressure and low pressure, and it is possible to reduce the electric power input to the compressor and it is also possible to make small the piping resistance of the whole cycle during room-heating of the refrigerating cycle.

IPC: H01L21/285
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a method of forming a fine low-resistance polysilicon silicide wire, which forms a MOS FET transistor. SOLUTION: A polysilicon wire 18 is formed on a semiconductor main body 12 and a titanium layer 26 is deposited thereon. Before a reaction step previous to the deposition of the layer 26 or subsequent to the deposition of the layer 26, gas, which does not give a bad effect to the following silicification reaction, is used to perform an injection of the gas in the layer 26. As the gas, noble element gas such as argon, krypton, xenon or neon gas is used. Then, the titanium layer 26 is reacted with the wire 18 to form a titanium silicide layer 27. The dimension of C49 grains in the layer 27 is decreased by the injection of the gas. As a result, a conversion of the layer 27 into a C54 phase is facilitated. Lastly, the layer 27 is annealed to convert the layer 27 from a C49 phase into the C54 phase.

Filed: 1990-06-04
Abstract: PURPOSE:To correct the quantity of light by forming an interference film capa ble of shifting the spectral characteristics of the film to the short wavelength side and the light quantity is changed and reduced. When the incident angle of light upon the film is increased, then applying an interference film having the spectral characteristic correcting a change in the light quantity. CONSTITUTION:A solid line R shows a characteristic curve at incident angle O deg. and a broken line S shows a characteristic curve at incident angle 20 deg.. Namely, the characteristic curves R, S temporarily reduce their transmission factors in the vicinity of 600nm and then increase them again from the vicinity of 700nm at which the sensitivity of a photosensitive body disappears. Thereby, the drop of the transmission factors in the vicinity of 500 to 600nm due to the shift of filter characteristics to the short wavelength side based upon the incident angle is corrected so as to be increased in the vicinity of 650 to 700nm. The interference filter having said characteristics can easily be formed by superposing two kinds of dielectric substances having respectively different refractive indexes.

Title: Noncontact mechanical seal
Inventor: ISSHIKI NAOJI
IPC: F16J15/34
Filed: 1988-06-14
Abstract: PURPOSE:To enable stable noncontact sealing and reduce a gap on sealing faces by providing a gas passing portion for allowing a high-pressure side gas to pass through on a sealing end face portion which is at least formed with a multiple porous material of one or both seal rings. CONSTITUTION:A high pressure gas on a high pressure side x which flows in from a vent hole 7 passes through a porous sealing end face portion 6 and flows out toward a fixed ring 2 from a porous end face. At this time, the pres sure distribution of the gap (g) on sealing faces is indicated by the lines (a), (b), (c) while indicating a pressure distribution which the rear end face of the seal ring 1 receives by the line (d). Thus, when a seal ring 1 is closely attached to a fixed ring 2, the pressure distribution on the sealing face becomes high as shown by the (c) line. On the other hand, as the seal ring 1 is separated from the fixed ring 2, the pressure of the gap (g) becomes low as shown by the (a) line by the principle of nozzle generating suction force. Therefore, finally, the pressure of the gap (g) is balanced with the pressing force against the seal ring 1 in the vicinity of the (b) line, enabling a stable operation in this condition.
