Title: Depositing method of boron layer
Inventor: SEKI YASUKAZU
IPC: C23C16/28
Filed: 1983-05-26
Abstract: PURPOSE:To deposit a boron protective film having excellent resistance to chemicals and wear on a base body of a low temp. by putting the base body in a vacuum vessel, heating said body, introducing gaseous diborane into the vessel, and generating a glow discharge in the vessel. CONSTITUTION:A base body 12 is placed on a cathode 3 in a vacuum vessel 1, and the inside of the vessel 1 is evacuated to a high vacuum. A regulating valve 10 is throttled to decrease the evacuating speed of an evacuating system 9 and at the same time diborane is introduced through a volume controller 8 into the vessel 1. The pressure in the vessel 1 is regulated to about 0.1-10Torr. The body 12 is preliminarily heated to a prescribed temp., for example, about 300 deg.C by a heater 5. When a glow discharge is generated by impressing a voltage between the electrodes 2 and 3, the diborane is decomposed and a boron film is formed on the surface of the body 12. The optional protective film is easily formed at a low temp. on the surface of the insulating base body, etc. by the above-mentioned method.

Title: Refrigeration source device
Inventor: UMEMOTO MASAO
IPC: C09K5/00
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To obtain a refrigeration source device which can be easily produced by a user, can be conveniently handled, is freed from a hazard, can generate low temperature capable of cooling or refrigeration over a long period of time by holding a direct contact type refrigerant prepared by direct contact of a frozen solid with a freezing mixture in a heat-insulation space. SOLUTION: The freezing mixture is exemplified by a hydrochloride, a nitrate, a thiocyanate, an alkaline earth sulfate or hydrochloride n-hydrate or a mixture thereof. For example, it is a combination of NaCl with NH4 NO3 or a mixture of KNO3 with NH4 Cl. The frozen solid is the most suitably ice. The direct contact of the frozen solid with the freezing mixture can be practiced, for example, by previously making a frozen solid, placing it in a bag, and adding a freezing mixture to the bag so as to realize direct contact therebetween. It is necessary that the refrigerant is placed in a heat-insulation space such as a heat-insulation container made of e.g. foamed polystyrene to keep it in a closed state. The freezing mixture may be a concentrated solution instead of a solid.

Title: Line interruption detection circuit
Inventor: YOSHITANI YUJI
IPC: H04B17/00
Filed: 1990-04-09
Abstract: PURPOSE:To detect line interruption due to clock interruption and to allow the circuit to cope with plural transmission speeds by monitoring the period of a signal resulting from differentiating a 1st control signal with a clock based on a 2nd control signal used for decoding processing. CONSTITUTION:A differentiating circuit 211 receiving a decoded data control signal outputs a derivative signals for a half period of a clock as a control pulse. A control signal generating circuit 221 generates inverted and noninverted signals from the inputted decoding control signal and selects the generated signal whose leading timing is dissident with an output timing of the decoded data control signal and outputs the selected output. The control pulse from the circuit 211 is 1/2 frequency-divided by a FF 243 in an access period detection circuit 241 and inputs the result to an exclusive OR gate 247. Moreover, the signal from a selector 231 in the circuit 221 is 1/2 frequency-divided by a FF 245 and inputted to a gate 247, from which an exclusive OR signal going from 0 to 1 at the rising of the output signal of the selector 231 is outputted, and a FF 249 fetches the exclusive OR output synchronously with the rising of the output signal of the selector 231 and outputs its inverting output.
