Title: Registering method of optional character
Inventor: ASAKA FUMIO
IPC: G06F17/21
Filed: 1982-04-30
Abstract: PURPOSE:To faciltate an easy production and registration of a new optional character, by displaying a common character or registered optional character with magnification on a dot matrix screen to perform a correction and editing for each dot. CONSTITUTION:A common character of a registered optional character is displayed with magnification on a dot matrix display screen 1. For instance, ''a'' is displayed to obtain a pattern 4 (a) of dotted lines, and at the same time, sq. rt.  is displayed to obtain a pattern 2 of a dotted line. Then the ''a'' of the pattern 4 is shifted right horizontally by (x), and at the same time the sq. rt. of the pattern 2 is shifted right horizontally by (y), respectively. Thus a pattern 3 of sq. rt.  is formed together with a pattern 5 of (a). In such a way, a new optional character can be produced and registered in a simple way. It is naturally possible to shift these patterns vertically and then obliquely for editing.

Title: Memory backup system
Inventor: YASUDA AKIRA
IPC: G06F11/08
Filed: 1980-05-31
Abstract: PURPOSE:To improve the efficiency of use of a computer by completing an interruption routine without a mutual check on data restoration between a floppy disk and an RAM when information other than backup information is being read from the floppy disk. CONSTITUTION:Between timer times of the 1st and 2nd timers 4 and 5, check sum data based upon readout data from an RAM 2 and a floppy disk device 3 is generated by a CPU1 and then collatd with previously stored check sum data. When the both do not coincide with each other, the data of the device 3 and RAM2 are mutually restored to perform a high-reliability backup. On the other hand, when information other than backup one is read out from the device 3, the CPU1 complets an interruption routine while omitting a check on the check sum data, thus giving priority to processing which corresponds to a read of data other than backup one high in access frequency. Therefore, the efficiency of use of the computer in the memory backup system is improved.

Title: Thermosensitive head
Inventor: SUZUKI YASUAKI
IPC: B41J2/335
Filed: 1988-03-29
Abstract: PURPOSE:To obtain high-quality images at low cost by providing high resistance sections between either common electrodes or signal electrodes or both which correspond to each dot, and between either common electrodes or signal electrodes or both which correspond to adjacent dots. CONSTITUTION:Common electrodes 1 and signal electrodes 2 are opposed to each other at positions corresponding to dots, and film resistors 3 are arranged between these electrodes. Holes are provided between the adjoining electrodes and this section is highly resistant. On the thermosensitive head, normally hundreds to thousands pieces of the signal electrode are arranged in parallel and the thermal distribution varies according to energy distributed to each electrode 2, thus contributing to the printing of intermediate tone images. At that time, if a signal is sent to the signal electrode 21, a pulsed current 61 runs from the common electrode 11, and the resistor section generates heat. However, due to the hole 4, the generation of heat near the hole is prevented and instead, only the desired section generates heat to enable correct printing. In addition, the flow of a little amount of heat exists because all the intervals between the adjoining electrodes are not necessarily cut off. Especially the dots of an image in a low density section spread properly in an intermediate tone visualization and this contributes to the improvement of image quality.

Abstract: PURPOSE: To eliminate trouble such as combustion failure and improve safety and reliablity by supplying a current to a proportioning valve to detect the current by switching it OFF or modifying it to a small current from which a detection signal is not obtained, and judging abnormality when the detection signal is obtained. CONSTITUTION: When a faucet 7 is opened and a water passing signal is ascertained by a water flow rate sensor 13, 100% of a PMW signal is outputted, and a current for a proportioning valve is supplied at a maximum value to the proportioning valve 11. In this case, a transistor 30 in a current detecting circuit 29 for the proportioning valve is turned ON, and the output signal is ascertained. On the other hand, the proportioning valve 11 is fully opened, and the sticking of a valve body is released. Then, upon acertaining the lapse of a certain period of time, the PWM signal is made to 0%, and the current to the proportioning valve is switched OFF. In this case, whether the transistor 30 in the current detecting circuit 29 for the proportioning valve is in an ON state is ascertained.  A primary valve 10 and a main valve 12 are opened, and ignition is controlled, but it is judged that parts in a filter circuit 24, a volumetric setting circuit 25 for a gas flow rate, etc., to which the current for the proportioning valve is fixedly outputted, become defective, and ignition is not controlled.

Abstract: PURPOSE:To increase the steam generation quantity of a boiler and alleviate the load of a pure water manufacturing device by introducing saturated water of a steam accumulator into a feedwater heating deaerator and recovering the saturated water as pure water fed to the boiler. CONSTITUTION:During the blow-kneading process of a convertor, a part of generated steam is introduced into a deaerator 21 for heating and a feed water pump 28 starts, then feedwater from a feed water tank 15 is introduced into the deaerator 21 via a feedwater regulator valve 30 which opens or closes according to a signal from a water level transmitter 29 of the deaerator 21 in order to maintain a set water level. Since extraction of saturated water in an accumulator 6 is controlled through operation of a blow control valve 13 by means of the water level and the internal pressure, erosion of piping 4, valve 5 and the like can be prevented. Further, extracted high temperature water is introduced into a boiler drum 2A to raise the entrance temperature of the deaerator 21, and increases the quantity of steam generated in the boiler.

Title: Method for controlling defrost of refrigeration circuit
Inventor: ANDO KENJI
IPC: F25B47/00
Filed: 1988-03-28
Abstract: PURPOSE:To prevent an oil in a compressor from being ejected into a refrigeration circuit in case of a hot gas defrosting operation by supplying a hot refrigerant gas to a bypass pipe while increasing an operation cycle of the compressor after decreasing the operation cycle of the compressor so as to reduce a pressure difference between high pressure and low pressure sides. CONSTITUTION:When an adhesion of frost on an evaporator 4 is detected by a frost detecting sensor 11, a rotary compressor 1 is driven at a minimum operation cycle so as to decrease a pressure difference between high pressure and low pressure sides, and after this pressure difference becomes equal to a prescribed pressure or lower, a number of revolutions of the rotary compressor 1 is raised simultaneously with an opening of an electromagnetic valve 6. The evaporator 4 is defrosted by a hot refrigerant gas supplied through a hot gas bypass pipe 5 to the evaporator 4. An oil in a enclosed vessel 7 is not ejected into a refrigeration circuit though the inside of the enclosed vessel 7 is communicated with the evaporator 4 through the hot gas bypass pipe 5, since a hot gas defrosting is started after the pressure difference between the high pressure and low pressure sides of the refrigeration circuit becomes small.
