Title: Air conditioner
Inventor: AKIYOSHI TAKANORI
IPC: F24F5/00
Filed: 1991-02-22
Abstract: PURPOSE:To reduce an air deflection sound and also to improve a strength against torsional vibration by a construction wherein a first fitting flange of a base main body and a part to be set of the main body of an air conditioner which is to be in contact with the first flange are slanted along the direction of blowing of a propeller fan. CONSTITUTION:A flange 13a of a base main body 13 is so slanted along the direction of blowing of a propeller 4 as to become higher from the front part toward the rear. Besides, each surface part of a bottom part 1b whereon the flange 13a is set is so slanted as to correspond to the slanted flange 13a, and a slanting surface part (a part whereon the main body of an air conditioner is to be set) 16 is formed in the aforesaid surface part. Therefore the interference of air and catching-in thereof are lessened considerably, while a pressure receiving area receiving torsional vibration is increased, and the surface contact effected thereby produces a counter force against the torsional vibration, weakening a force causing the torsional vibration. According to this constitution, an air deflection sound can be reduced and also a strength against the torsional vibration is improved.

Title: Receiver for television
Inventor: MINAGAWA TERUO
IPC: H04N5/44
Filed: 1982-02-26
Abstract: PURPOSE:To receive a signal precisely in a television provided with an automatic channel selecting device, by generating the signal for a fixed period at the detection of the signal and making the signal maximum gain status. CONSTITUTION:The automatic channel selecting circuit 7 in a television which sweeps and selects a channel automatically applies a sweeping voltage to a tuner 2 to sweep channels. At the detection of a video signal outputted from a video detecting circuit 4, the automatic channel selecting circuit 7 stops sweeping for a fixed period and applies an output to an AGC circuit 5 and AGC reset circuit 6 so that the receiver is actuated at the maximum sensing condition. Thus signals can be precisely detected without missing them even if they are extremely fine signals and a required channel can be selected.

Filed: 1995-02-17
Abstract: PURPOSE: To improve the testing of a ferroelectric memory by performing the heat treatment of a wafer at a temperature lower than the Curie temperature of the ferroelectric substance of a memory circuit, testing whether a die is conforming or not, annealing the wafer at a temperature being equal to or higher than the Curie temperature of the ferroelectric substance, and suppressing the influence of printing deterioration of a switched charge. CONSTITUTION: An improvement procedure flow 30 follows the process of baking 38 for screening retention force. The baking for screening retention force is performed at a lower temperature than the Curie temperature of approximately 150 deg.C so that a week part can be shaken off. Once the wafer is mechanically tested and is subjected to baking for screening retention force, stored data are read (process 40) and an opposite data state is tested. After the testing process 40 is performed, a recovery annealing process 42 is executed. The preferable recovery annealing process 42 is performed at approximately 400 deg.C in nitrogen. The annealing temperature is equal to or higher than the Curie temperature of a ferroelectric body.

Filed: 1990-02-08
Abstract: PURPOSE:To facilitate a stable and high speed switching operation of a DC-DC converter by providing a choke coil having a core on which are wound four windings with the same number of turns. CONSTITUTION:A chock coil L1 is constituted by applying windings N1-N4 to a single core. All the winding turns of the respective windings N1-N4 are identical. In a normal operation, a circuit is so constituted as to make the windings N1 and N4 or the windings N3 and N2 of the choke coil L1 have subtractive polarity directions and, further, the winding turns of the windings N1-N4 are identical. Therefore, the choke coil L1 plays no operational role. On the other hand, concerning a mode wherein a transistor Q1 is switched from a conducting state to a non-conducting state in a short time and a charge current showing a large peak value is applied to a transistor Q2, the circuit is so constituted as to make the windings N1 and N2 of the choke coil L1 connected to additive polarity directions. As a result, the peak value of the charge current can be suppressed to a low value.

Filed: 1982-02-22
Abstract: PURPOSE:To recognize a voice without hindrance due to sounds from an acoustic means, by activating a voice recognizing means after lowering the level of the acoustic pressure of a sound generating part of the acoustic means. CONSTITUTION:When a driver wants to open or close a window 100, operate a ratio, or light or extinguish a lamp 120, he operates a switch 19. When the switch 19 is closed, an interruption signal is given to a controlling circuit 50. In accordance with this signal, the circuit 50 discriminates whether a power-on command is given to a radio 110 from a radio controlling circuit 80 or not. If the power-on command signal is given to the radio, the circuit 50 outputs a control signal, which lowers the level of the acoustic pressure of the radio 110, to the circuit 80. The circuit 80 takes in this control signal and gives a sound volume switching signal to the radio 110. In the radio 110, the level of generated sounds is lowered on the basis of this sound volume switching signal.
