Patent JP-S56117018-A (JP)
Title: Temperature controller
Inventor: SHIGEKUSA HISASHI
IPC: F24H3/02
Filed: 1980-02-20
Abstract: PURPOSE: To control and measure the temperature of a hot air correctly and easily by changing a preset temperature sequentially in a predetermined order in response to a temperature measurement command and displaying the preset temperature at which a coincidence is obtained between the measured temperature and the preset temperature.  
     CONSTITUTION: A differential amplifier 4 obtains a difference between the preset temperature preset by a digital setting device 2 and the measured temperature measured by a temperature detector 3. When the measured temperature is higher than the preset temperature, the differential amplifier 4 outputs the difference therebetween as a positive difference. To the contrary, when the measured temperature is lower than the preset temperature, the differential amplifier 4 outputs the difference therebetween as a negative difference. Only when the two temperatures coincide with each other and the difference therefore becomes zero, a comparison output from a comparator 9 is inverted. Accordingly, it is determined by this that the preset temperature at this time is equal to the detected temperature. Thus, the current temperature can be measured correctly.

Title: Information recording method
Inventor: TAMEGAI MASAHIRO
IPC: G06F12/00
Filed: 1994-02-17
Abstract: PURPOSE:To reduce the capacity of a directory area and to simplify the process of application software by recording sector management information containing- defect information on a recorded file as a 2nd directory when a recording medium is unloaded from a device. CONSTITUTION:While an optical card 1 is loaded on a drive 31, the sector management information on the file including information on a defective sector is stored in the internal memory of an MPU 33 and when the optical card 1 is unloaded from the drive 31, the information is read out of the memory and written on the optical card 1 as the 2nd directory. Consequently, it is not necessary to record the sector management information including the defect information in the directory each time the file is recorded, and the capacity of the directory area is reducible. Further, the sector management information is recorded before the optical card 1 is unloaded, so application software which handles only data needs to only record the data without paying attention to the directory and the processes is simplified.

Title: Offset adjustment circuit for operational amplifier
Inventor: YUASA MASAMI
IPC: H03F3/347
Filed: 1990-01-31
Abstract: PURPOSE:To realize an offset adjustment circuit not subjected to the effect of a temperature change and precluding the possibility of unbalancing differential balance by varying a DC current in a couple of current source circuits provided with a couple of resistors and a couple of bias circuits. CONSTITUTION:When nothing is connected to a connection mid-point S (terminal pin T4) between voltage division resistors R5, R6 and resistance values r3, r4 of resistors R3, R4 are selected equal, emitter currents I3, I4 of transistors(TRs) Q7, Q10 are made equal to each other. Since a term of a base-emitter voltage VBE is not included in equation representing the current, even when the voltage VBE is changed due to temperature, both the currents are unchanged. Furthermore, even when the resistance values of resistors R1-R6 changes due to temperature, since they are formed in an IC, the combined resistance is unchanged. A voltage VS at the midpoint S is varied by a variable resistor R9 and a base voltage of the TRQ10 is changed, then the current I4 is changed. Thus, emitter currents I3, I4 of the TRs Q7, Q10 are increased in terms of gain by current mirrors 4, 5 based on an offset adjustment range to obtain adjustment currents I1, I2.
