Title: Decimal division system
Inventor: SATO NOBUYOSHI
IPC: G06F7/52
Filed: 1988-10-13
Abstract: PURPOSE:To reduce the number of times of memory access and to accelerate a decimal division processing at an office computer level economically by providing a means to obtain the estimation of a quotient, an addition means, an addition/subtraction means, and a correction means in case of generating a negative value in a division result. CONSTITUTION:The plural high-order digits of a dividend are compared with the plural high- order digits of a divisor by using the subtracter 11 of the means 1 to obtain the estimation of the quotient, and when it is dividend < divisor, the plural high-order digits of the divisor are shifted by one digit, then, they are subtracted from the plural high-order digits of the dividend. And such operation is repeated until a subtraction result shows a negative number, then, the estimated quotient(C) of the quotient can be obtained. Next, the arithmetic operation of (divisor X quotient (C)) is performed by using an adder 21, and after that, the verification of (dividend - (divisor X quotient C)) is performed by using an adder/subtractor 31. When the negative number is obtained as a result, a subtraction result is restored to a positive number by adding the divisor, and a number(estimated number of quotient - 1) is set as a new quotient, and a true quotient and a remainder can be found by performing such arithmetic operation repeatedly. In such a way, it is possible to accelerate the decimal division processing economically at the office computer level by reducing the number of times of access.

Title: Microcomputer system
Inventor: MIYOSHI NORIYUKI
IPC: G06F1/24
Filed: 1992-09-28
Abstract: PURPOSE:To dispense with a voltage detecting circuit constituted of an IC by deciding whether a backup voltage becomes below a memory holdable voltage or not, based on an output voltage of an integration circuit. CONSTITUTION:A microcomputer 2 migrates to a backup mode, when a hold terminal HOLD becomes a low level at the time of service interruption, and fetches an output voltage V3 of an integration circuit 3, when a power source V1 is reset and a reset signal is applied from a power-on reset circuit 4. Subsequently, based on this output voltage V3, whether a backup voltage V2 at the time of service interruption becomes below a memory holdable voltage or not is decided, and when it is decided that it becomes below the memory holdable voltage, initialization of a memory is executed. In such a way, a voltage detecting circuit for detecting whether the backup voltage at the time of service interruption becomes below the memory holdable voltage or not becomes unnecessary.

Title: Freezer device
Inventor: KURODA MIKIHIKO
IPC: F25B1/00
Filed: 1988-10-13
Abstract: PURPOSE:To enable occurrence of trouble to be reduced by a method wherein a temperature of heat exchanging fluid such as air before its passing through an evaporator is detected and when a temperature difference between an atmospheric temperature and refrigerant evaporation temperature is lower than a standard temperature difference, a degree of opening of an electric expansion valve is forcedly varied in a valve opening direction. CONSTITUTION:In case that a lack of gas occurs due to a holding of foreign material in a refrigerant circulating passage having an electric expansion valve 16, a reduction in temperature of an indoor heat exchanger 20 is reduced due to a reduction of amount of evaporating refrigerant in the indoor heat exchanger 20 and it is judged that a temperature difference is lower than a standard temperature difference. As a result, an instruction for varying a degree of opening of the electric expansion valve 16 to an upper limit degree of opening in a variable range is outputted to a valve control part 48. Then, after elapsing a predetermined period of time, a temperature difference after varying a degree of opening is compared with the standard temperature difference, its gaseous state is released and an amount of refrigerant corresponding to a degree of opening is flowed into the indoor heat exchanger 20, thereby a temperature reduction of the indoor heat exchanger 20 is generated and it is confirmed that the temperature difference is higher than the standard temperature difference.

Abstract: PROBLEM TO BE SOLVED: To obtain a suppressant material, capable of lowering interaction properties of microorganism with an object material, i.e., a polymer material and useful as medical equipment, building and food packaging materials, etc., by using the polymer material and a specific component in combination. SOLUTION: This suppressant material to the attachment of microorganisms is obtained by adding a surfactant (especially about 0.1-40wt.% phospholipid) to a polymer material, e.g. polyethylene, polyvinyl chloride or a silicone rubber and carrying out the extrusion molding, etc., or adding various surfactants in an amount of 3-20wt.% based on an active ingredient of a flexible silicone resin, vigorously stirring the resultant mixture, providing a coating liquid containing the surfactants, immersing a silicone sheet in the prepared coating liquid and subsequently drying the resultant silicone sheet. An antimicrobial substance is blended in the suppressant material to the attachment of the microorganisms to thereby afford a composition having both the suppressing properties to the attachment of the microorganisms and antimicrobial activities. In addition, an electroconductive substance can be blended to thereby provide an electroconductive composition having suppressant properties to the attachment of the microorganisms and further antimicrobial activities in combination.

Title: Slip-cast forming
Inventor: TANAKA ATSUSHI
IPC: B28B1/26
Filed: 1989-10-03
Abstract: PURPOSE:To improve a dimensional accuracy to facilitate mounting and removing a rubber membrane necessary for cold hydrostatic pressurization by removing an outer die and drying a compact after forming the compact composed of a raw material powder on the outer periphery of a core, by covering the compact with the rubber membrane in a state, where the core is left as it is, and by subjecting the compact to the cold hydrostatic pressurization. CONSTITUTION:A slip suspending a raw material powder in dispersions is injected into a forming die and when a compact 6 is formed, an outer die 2 is removed and a compact is dried together with a core 1. In this case, because the compact 6 is covered with a rubber membrane 5 in a state where the core 1 is left as it is, the rubber membrane 5 can cover the compact easily. Then, the compact 6 covered with the rubber membrane 6 together with the core 1 is subjected to cold hydrostatic pressurization. Subsequently, when the core 1 and compact 6 are heated at a temperature not lower than the fusion temperature of a low-melting alloy, the core 1 is fused and removed and the compact 6 is completed. Thus, it is possible to obtain the compact 6 excellent in a dimensional accuracy and the rubber membrane 5 is also mounted and removed easily.

Title: Disk reproduction device
Inventor: KAMIYA SHINGO
IPC: G11B19/02
Filed: 1989-10-03
Abstract: PURPOSE:To prevent reproduction sound from being affected by means of the rotary speed of a disk by retreating a pickup for the prescribed number of tracks whenever a recording medium rotates for the prescribed number of times, storing reproduction information, executing the cross fading-processing of reading information and information obtained by means of delaying the information and outputting them. CONSTITUTION:Whenever the recording medium 1 rotates for the prescribed number of times, a pickup position control means 5 retreats the pickup 11 for the prescribed number of the tracks as against a reproduction travel direction and information reproduced by the pickup 11 is stored in a storage means 13. Then, a storage information reading means 8 reads storage information in such a way that storage information in the storage means 13 is repeated for prescribed reproduction time. A delay means 14 delays the read information for prescribed time, and a cross fading-means 15 cross fading-processes and outputs read information from the storage information read means 8 and output information from the delay means 14. Thus, reproduction sound is prevented from being affected by rotary speed of the disk 1.
