Title: Heat exchange device
Inventor: MIYAJIMA NORIYOSHI
IPC: F25B39/02
Filed: 1984-06-13
Abstract: PURPOSE:To make cooling and heating in time of ventilation performable so smoothly, by setting up a heat exchanger in an air passage, while letting air at both upper and lower sides of the heat exchanger exchange their heat in a state of a refrigerating cycle being stopped. CONSTITUTION:In the course of heating, dampers 20 and 21 are selected to a full-line position only in time of ventilation loss recovery, and a valve 25 is closed, but in refrigerating cycle stoppage, since refrigerant pressure inside a pipe attached to a feeler cylinder 28 will in no case come down lower beyond 0.5mb than the saturated pressure inside the feeler cylinder 28, an expansion valve 27 is closed. And, due to outside air intake, an in and outside air selector damper 60 opens an outside air intake port 2b whereby intake air flows into an upper side 2a of an evaporator 1. On the other hand, since air pressure inside a car is high in time of the outside air intake, cab air enters at an inside air intake duct 19, giving heat to a liquid refrigerant inside the evaporator 1 at a lower side part 1b, and the air itself is cooled and then is discharged outside from a duct 18. Air passing through an upper side part 1a receives heat, thus its temperature rises.

Title: Recording device by thermal copying
Inventor: SUGIURA SUSUMU
IPC: B41M5/382
Filed: 1979-09-25
Abstract: PURPOSE:To prepare a nonimpact recording device which is of a simple structure and can scan as wide as the width of an ink supporter more effectively by a method wherein radiating energy is scanned obliquely to the moving direction of an ink coating surface. CONSTITUTION:In a recording device by thermal copying where hard ink in an ink supporter 2 is melted by radiating energy and a copy is made on a recording sheet 1, the radiating energy is made to be scanned obliquely to the moving direction of an ink coating surface. In other words, in a line printer, for example, when a laser beam begins scanning at A0 and ends scanning at B0, it enters a fly-back period, the laser rays are put off and the ink supporter sends character pitches from A0 up to A1 by a feed motor. The laser rays start lighting a lamp at A1 and resume scanning. The laser rays make oblique scanning by a constant speed rotation of the ink supporter. When heat beam scanning is made in a right and left direction in the conventional manner, the ink supporter is not used efficiently and another scanner is required in a width direction of the ink suppoerter and the cost of recording device is hiked up.

Title: Amplifying circuit
Inventor: UEHARA YOUICHI
IPC: H03F1/00
Filed: 1981-08-07
Abstract: PURPOSE:To prevent a bounce voltage from being generated at an output terminal, by clamping the output terminal of an operational amplifier by the feedback voltage of the operational amplifier. CONSTITUTION:When a positive-polarity input voltage VIN is applied to the noninverted input terminal of an operational amplifier AMP, a voltage VOUT at the output terminal becomes large, and therefore, a transistor TR Q1 is turned off. A feedback voltage VFB rises later and becomes equal to the voltage VIN. When the voltage VIN falls and the voltage VOUT becomes smaller than the voltage VFB, the TR Q1 is turned off, and the voltage VOUT is clamped by the voltage VFB, and the bounce voltage is not generated. When the voltage VIN has the negative polarity, the voltage VOUT is inclined to fall to the negative, and therefore, the TR Q1 is turned on to clamp the voltage VOUT in the voltage VFB.

Title: Method of making output of transmitted ultrasonic pulses constant
Inventor: SONOMURA MASARU
IPC: G01S7/524
Filed: 1978-10-09
Abstract: PURPOSE:To make the output of ultrasonic pulses constant without causing oscillation even if the width of the pulses is small, by controlling the power of each succeeding pulse depending on the stored value of the preceding. CONSTITUTION:The continuous AC output (a) of an oscillator OSC is gated by a trigger pulse (b) to produce a burst signal (c). The burst signal is amplified and then applied to a vibrator to produce ultrasonic pulses. When an ultrasonic pulse is produced by a tregger pulse N, the output power of the pulse is stored in a memory 1. The sotred power is compared with a setpoint. an output corresponding to the difference between the compared values is applied to a calculation circuit to compensate a control level in a memory 2. A power amplifier is regulated to the compensated control level as to the next trigger pulse (N+1) to transmit an ultrasonicpulse from the vibrator. Within the repetition of such processes at several times, the output power is made constant.
