Title: Ac voltage controller
Inventor: MURAMATSU KAZUHARU
IPC: H02P27/02
Filed: 1990-08-24
Abstract: PURPOSE:To absorb surge voltage sufficiently and to reduce loss in the circuit without increasing the capacity of a capacitor in a snubber circuit by connecting a main switching element in parallel with a switching snubber circuit comprising a series circuit of a capacitor and a switching element incorporating a diode. CONSTITUTION:Upon turn ON of a main switching element TR1 within positive half period of a power supply 10, load current flows through a diode D1, the main switching element TR1, and a diode D2 into a loas 12. Upon turn OFF of the main switching element TR1, a switching element TR2 is turned ON and a capacitor C3 in a switching snubber circuit 30 is charged by the flywheel current of the load 12 with a polarity shown on the drawing. When the main switching element TR1 is turned ON and the switching element TR2 is turned OFF, the capacitor C3 is discharged through the element TR1, a diode d2 built in the element TR2 and stray reactance thus charging the capacitor C3 with reverse polarity.

Title: Constitution method for memory buffer
Inventor: ABE YOSHIHIRO
IPC: G06F17/21
Filed: 1991-09-02
Abstract: PURPOSE:To secure a memory buffer by means of adjusting it to the number of characters even if data has the large number of characters in one line so as to reduce the consumption quantity of a memory by dynamically and variably securing the number of the characters for one line. CONSTITUTION:The initialization of the number of the characters for one line in the memory buffer is set to be 128. When the number exceeds 128, the number of the characters for one line is increased by 128 characters so as to secure the memory again. At the time of reading 50 characters in a first line, 200 characters in a second line, 128 characters in a third line and 100 characters in a fourth line as text data, the number of the characters is counted and read one line by one, and a program is generated to decide the secured memory by the number of the characters. Thus, the memory buffer of 128 characters for the first line, 256 characters for the second line, and 128 characters for the third and fourth lines is secured. The memory buffer is secured in accordance with the number of the characters without the number of the characters for one line being fixed. At the time of additionally inputting only one character for the third line, the memory buffer is set to be 256 characters so as to secure it.

Title: Air conditioner
Inventor: TAKAHASHI NORIO
IPC: F24F11/76
Filed: 1990-08-27
Abstract: PURPOSE:To enable always keeping the atmosphere comfortable by providing a means for changing the target temperature corresponding to a set temperature for bringing the temperature of the room to a desirable point and a means for changing the number of revolutions of an indoor fan according to the detected temperature of the room. CONSTITUTION:When the temperature of the room has fallen already of falls below (a set temperature + 0.25 deg.C) at the start 'SAWAYAKA' operation, the control of an indoor fan 15 shifts from weak wind to breeze. This shift prevents the room air from giving a chilly feel as its temperature falls close to the set point. The start is ended when the temperature of the room has reached a target temperature (= the set temperature) and a timer 12 has finished counting a preset time T. With the target temperature altered to (the set temperature + 0.25 deg.C) the operation shifts to a post-start routine. The increase in the target temperature causes the temperature of the room to rise, but since it is only by 0.25 deg.C that the target temperature has been increased, the compressor 16 keeps running although the rotation is at low speed and the temperature of the room, restrained from a rapid rise, increase slowly. The control of the indoor fan 15 shifts from breeze to light wind so as to free the people from a feeling of discomfort due to the rise in the temperature of the room.
