Abstract: PURPOSE:To realize a VTR with a compact, light-weight and thin-gage structure, installing the unified capstan motor and reel motor between a pair of reels and at the same time simplifying a loading mechanism. CONSTITUTION:A capstan motor that drives a capstan to feed a tape in a constant speed in the recording and reproducing times is unified with a reel motor that drives reels 20 and 21 in the fast forwarding and rewinding times into a motor 17. This motor 17 is installed between the reels 20 and 21. A capstan 15 is driven by a capstan belt 23; and the reels 20 and 21 are driven by an idler 19. On the other hand, flexible racks 26 and 27 that engage guide post members 24 and 25 and then move are used in the tape loading mechanism. These racks 26 and 27 are moved synchronously with each other by a pinion 28. In addition, the motor 17 plus the tape loading mechanism are made flat in structure to decrease the thickness of a rotary head cylinder 14 along with application of a direct drive system.

Abstract: PURPOSE: To provide a heat pump type air conditioner, which is capable of cooling one room while heating the other room at the same time.  
     CONSTITUTION: High-pressure cooling medium gas discharged from compressor 1 is passed through four-way valve 2 and enters into outdoor heat exchanger 3. Here, since fan 13 is not operated, the gas is passed through check valve 4, three- way valve 6b and electromagnetic valve 12b, with no releasing of heat in the heat exchanger 3, and enters into indoor heat exchanger 7b, where the releases heat and is condensed, thus heating room B. Then, condensed cooling medium is passed through three-way valve 8b, connecting pipe 9 and three-way valve 6a, and pressure of the cooling medium is reduced to its evaporating pressure at cooling throttle medium is reduced to its evaporating pressure at cooling throttle means 11a. The gas is evaporated in indoor heat exchanger 7a and cools room A. Then, evaporated cooling medium is returned again to compressor 1 via three-way valve 8a and three-way valve 2

Title: Waveform shaping circuit
Inventor: GOTOU FUMIO
IPC: H03K5/1252
Filed: 1982-07-19
Abstract: PURPOSE:To attain the sure operation, by giving a difference between a threshold voltage of an inverter or a buffer connected to an output of an R-SFF3 and that of a reset gate of an FF. CONSTITUTION:An input signal (a) from a signal generating block K is applied to a set side element 3a and a reset side element 3b of the R-SFF3 via the inverter 1 and the buffer 2. Further, an output (d) of the FF3 is outputted to a counter 6 via an inverter 5. The threshold voltage of the inverter 5 is increased more than the threshold voltage of the reset side element 3b of the FF3. Thus, since the output stage inverter 5 is started after the positive feedback operation of the FF3 is started, no malfunction takes place.

IPC: G06F3/12
Filed: 1979-09-28
Abstract: PURPOSE: To make it possible to print a fixed quantity of data without exchange of the form even after detection of paper lack, by printing a fixed quantity of data in case that the print key is operated under the state where paper lack is detected by the paper lack detector.  
     CONSTITUTION: When paper lack detector 7 of printer 6 detects paper lack during report printing, detector 7 sends paper lack detection signal 8 to CPU1. If the print key of keyboard 3 is depressed under this paper lack detection state, the report of one-block components is printed on the residual paper. By this method, somewhat of data can be printed visually even after paper lack detection, and paper exchange is needless when residual data after paper lack detection is little.
