Title: Refrigerant heater
Inventor: WATANABE HIDEYUKI
IPC: F25B13/00
Filed: 1992-06-22
Abstract: PURPOSE:To easily dip heater means in liquid refrigerant and to hence prevent overheat of the means by arranging a plurality of baffle plate members at a predetermined interval in the means arranged on an inner wall surface of a vessel which is laterally long or laterally in the vessel. CONSTITUTION:A lateral refrigerant heater 1 comprises an input tube 3 and an outlet tube 4 arranged on an upper part of a vessel 2 which is laterally long, and heater means 5 arranged laterally therein. In this case, a plurality of baffle plate members 6 are arranged on a rodlike heater 5a of the means 5 or at a predetermined interval on an inner wall surface of the vessel 2. A flow of a two-phase refrigerant is shut OFF by the members 6 to reduce a speed of the flow, thereby allowing liquid refrigerant to be easily stayed in the vessel 2. Even if a surface of the liquid refrigerant becomes oblique in the vessel 2, the refrigerant is shut OFF at a predetermined interval by the members 6 thereby to suppress a height difference due to the oblique liquid surface, thereby dipping the entire heater 5a in the liquid refrigerant.

IPC: H04B10/079
Filed: 1988-06-30
Abstract: PURPOSE:To minimize the power consumption of a light emitting section in a transmission section as required by outgoing a data request signal from a reception section at all times and allowing the transmission section to originate a data signal only when the transmission section enters a transmission enable range and is able to receive the data request signal. CONSTITUTION:In the case of applying data transmission by light between the transmission section 10 mounted on a movable member R and the reception section 20 installed stationarily, while the reception section 20 originates a data request signal to the transmission section 10 for a short period, the transmission section 10 originates a data signal to the reception section 20 in response to the reception of the data request signal. Thus, only when the transmission section 10 resides in the transmission enable range and the data signal reaches effectively the reception section 20, the transmission section 10 can originate the data signal, then the power consumption of the transmission section 10 is minimized.

Title: Electrode design to control uniform profile by plasma processing reactor
Inventor: SHIAMAKU SARIMIAN
IPC: H01L21/302
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide an electrode design to reduce the troubles of nonuniform etching on a large-diameter substrate. SOLUTION: An electrode facing an electrode to be etched in a reactor is shaped into a specified form capable of controlling the uniformity of the etching over the substrate. This is attained by a nearly dome-like electrode 104 involving a nearly pyramid and nearly hemispherical electrode. The nununformity of the etching is deemed to occur because of the excessive ion density in the center of the reactor. The domed electrode 104 diffuses high-concn. ions from the center of the reactor to the periphery of a substrate to thereby equalize the ion density distribution over the substrate being etched. Thus detected electrode is available in a diode tube plasma reactor, triode plasma reactor and ICP plasma reactor.
