IPC: F25B30/02
Filed: 1987-01-30
Abstract: PURPOSE:To reduce the unpleasant feeling of a user by a method wherein the difference between heated hot water temp. and bathtub water temp. is computed: when the difference is equal to a set value or less, the individual heating operation for the bath is carried out and when the difference exceeds the set value, the simultaneous operations of heating for the bath and space heating are carried out. CONSTITUTION:Indoor units A, B have indoor controllers 42, respectively; when room temp. is detected to be lower than a set temp. by an indoor thermostat 44, a demand signal for space heating operation is output from the controller 42 to an outdoor controller 41. To the bath controller 45 of a bathtub unit C a bath heating operation switch 46 and temp. sensors 38, 39 are connected. The hot water temp. Tin is read in by the sensor 38 placed at a water inlet pipe 24 and heated hot water temp. Tout is read in by the sensor 39 placed at a water outlet pipe 25: when those temp. difference DELTAT exceeds 6 deg.C, the operations of space heating and bath heating are carried out, and when DELTAT is 6 deg.C or less, the space heating operation is forcibly stopped and the operation is switched over to the individual operation of the bath heating. After the individual operation for the bath continues for two minutes, DELTAT is again computed and then the selection for the individual operation for the bath or the simultaneous operations of bath heating and space heating is again carried out.

Abstract: PURPOSE:To reduce power consumption while increasing working speed, and to operate a bipolar type semiconductor, device even at a low temperature by mounting superconductive ceramics having perovskite structure onto a semiconductor substance having an n p junction or a p-n junction and forming an emitter. CONSTITUTION:Superconductive ceramics 16 having perovskite structure are set up onto a semiconductor substance having an n-p junction or a p-n junction, and an emitter is shaped. When a superconductive substance is represented by (m), an m-p-n junction or an m-n-p junction is formed between the semiconductor substance and the superconductive substance (m), and the superconductive substance functions as the emitter. Consequently, bipolar operation is acquired. The emitter and a base 14 are Schottky-joined, and transistor operation is obtained. Since the emitter is shaped by the superconductive substance, series resistance related to the emitter is lowered, and a time constant is reduced. Accordingly, power consumption is diminished, working speed is increased, and the semiconductor device can be operated excellently even at a low temperature.

IPC: B41J11/02
Filed: 1987-02-03
Abstract: PURPOSE:To obtain a recording device in which almost no position shift occurs without limitation of the kinds of recording paper by providing an absorption part which absorbs paper on a paper feed member which transports the paper. CONSTITUTION:If a platen roller 1 is turned, an absorption part 5 which slightly protrudes from the platen roller 1 is thrusted into a pressure contacted area, and air in an absorption hole 6 is ejected, through an absorption hole 6 in a non-pressured contacted area, from a groove bottom of the platen roller 1. Later if the area in which the platen roller is thrusted comes out of the pressure contacted area, the sorption part 5 is restored to a home position, and negative pressure generates in the absorption hole 6 due to an increase of its volume. Subsequently, this negative pressure works as an absorptive force to paper 2, and the paper is securely fed by the absorptive force and the high friction force of the platen roller 1. If the thermal head 4 is energized while feeding paper, the ink of an ink sheet 3 is transferred to the paper, thus achieving recording with high accuracy. Furthermore, air enters the absorption hole 6 which absorbs, gradually and the paper is separated easily.
