Title: Data communication method
Inventor: ISHIMOTO KAZUYOSHI
IPC: H04L12/40
Filed: 1990-03-27
Abstract: PURPOSE:To reduce the communication time required absolutely by limiting a terminal station including an inverted data part for transmission mis-detection as a transmission reception data to part of stations among all terminal stations. CONSTITUTION:A terminal station including an inverted data part for transmission mis-detection resulting from an inverted data in addition to a substantial data part as a transmission reception data in a communication enable time is limited to part of terminal stations among all terminal stations. For example, an inverted data for transmission mis-detection resulting from an inverted data is sent and received between a slave station B1 and a master station A in addition to a substantial transmission data. The communication line between a slave station B2 and the master station A of a succeeding address is enabled of communication from a point of time of elapsed prescribed set time and in this case, only the substantial data is sent/received in this case. Thus, only a head data includes the substantial data and the inverted data for one frame period. Thus, the entire communication time is reduced to quicken the data communication and number of terminal stations is increased and the data length of the transmission reception data is extended.

Abstract: PURPOSE:To obtain exact distance measuring information by repeating light emission and non-light emission in a light emitting part, and interposing a circuit, for correcting an integrated value of an integrating part at the time of the light emission by an integrated value of an integrating part at the time of the non-light emission, between the integral part and an arithmetic part. CONSTITUTION:After the number of light emitting pulses, namely, an integral time has been determined, a light emitting part LED is set to a non-light emission, and by its integration time, an output from a PSD is integrated by integration circuits 3, 3', integrated values VAoff, VBoff by an offset variation, etc., caused by an offset shift, noise light, etc., are obtained, and these values are held in holding condensers 6, 6' by turning off analog switches 5, 5' and turning on analog switches 4, 4'. Subsequently, said integration is executed by making the light emitting part LED emit a light beam by the same integration time as the previous time, by turning off the analog switches 4, 4', and turning on the analog switches 5, 5'. In this way, distance measuring information is obtained from a difference of its integrated values VA, VB and the integrated values VAoff, VBoff which have been held in the holding condensers 6, 6'.

IPC: A23L3/14
Filed: 1990-03-27
Abstract: PURPOSE:To obtain a retort food resistant to discoloration in sterilization and deterioration of quality during storage by sealing a food having an air-content lower than a specific level in a flexible heat-resistant vessel, rotating the vessel while controlling the inner pressure of a sterilization apparatus and the inner pressure of the vessel to respective specific states and sterilizing the food under pressure with heat. CONSTITUTION:A food having an air-content of <=2% is put into a flexible heat-resistant vessel such as retort pouch, a cup made of synthetic resin, etc., and sealed. The amount of the food is smaller than the maximum capacity of the vessel. The vessel containing the food is placed in a sterilization apparatus (e.g. retort oven) and thermally sterilized under pressure while rotating and/or reciprocatively turning the vessel and controlling the inner pressure of the sterilization apparatus to be equal to or slightly lower than the inner pressure of the vessel. Since the vessel contains the necessary minimum amount of air, there is no problem of the discoloration of the obtained retort food with air in sterilization.

Filed: 1993-04-07
Abstract: PURPOSE:To produce a highly reliable chip type thermister excellent in solderability and soldering heat resistance in which fluctuation of resistance due to plating of enclosing electrode is suppressed easily at low cost. CONSTITUTION:A chip body stamped out from a green sheet for thermister is fired to produce a thermister body 10 and internal electrodes 11 are formed at the opposite ends of the body 10 while wrapping them. The body 10 is then coated with a dielectric inorganic layer 14 of 0.1-10mum thick over the entire surface thereof. A conductive paste containing a metal powder and an inorganic coupler is applied to the opposite end parts of the body 10 while wrapping them over an area smaller than the internal electrode and then the paste is fired at a temperature lower than the melting point or softening point of the inorganic layer. Consequently, a part of the underlying inorganic layer is fused to the inorganic coupler in the paste thus forming an external electrode 16. Subsequently, plating layers 18, 19 are formed on the surface of the external electrode.

IPC: G05B7/02
Filed: 1985-04-16
Abstract: PURPOSE:To prevent the overshoot and undershoot of a temperature controller, by actually directly adjusting the regulating valve of the controller by performing PID control corresponding to the proportional, integration term, and differentiation term of a deviation obtained in accordance with the sense output of a temperature sensor. CONSTITUTION:This temperature controller is constituted in such a way that the control mode which controls a regulating valve 9 is set correspondingly to the sense output of a sensor 3 and control for setting the opening of the regulating valve 9 to a set value is performed at the initial stage of operation. In the case of PID control, the control is made in accordance with Formula I. The M, M(o), Kp, p, Tim, Td, and (e) of the Formula I represent the manipulated variable (%) of the regulating valve, set position of the valve, proportional gain, proportional zone, integrated time, differentiated time, and deviation, respectively. In this invention, a coefficient Ki which varies correspondingly to the absolute value of the deviation (e) is introduced as the coefficient of the integration term. Namely, Formula II is obtained by deforming the integration term of Formula I and adding the coefficient Ki to the integration term. Then Formula III is obtained by using a value relying on the deviation (e) in the form shown in Fig. A as the coefficient Ki. Therefore, the integration term is given by Formula IV. Overshoot hardly occurs under the characteristic of this control.
