Filed: 1987-09-11
Abstract: PURPOSE:To ensure the judgement of the presence or absence of the occurrence of leakage and to prevent cracking and the like of a detecting element, by applying a power supply to a heater after an engine switch is opened, and reading the output voltage of the detecting element. CONSTITUTION:A heater power supply 7 is applied to a heater 2 for a specified time after an engine switch 3 is opened. Whether the output from a detecting element 1 is higher than a specified leakage judging value or not is judged with a leakage judging means 4. When it is judged that the leakage occurs with the leakage judging means, the application of the power supply to the heater is stopped when the engine switch is operated at the next time with a reference voltage correcting means 5. Correction for increasing the reference voltage of the detected signal, which is outputted from the detecting element, is performed. In this way, the leakage, which cannot be judged during the operating period of the engine, can be simply judged during the stopping period of the engine. The feedback control of an air/fuel ration can be performed under the state the power supply to the heater is stopped.

Filed: 1987-09-16
Abstract: PURPOSE:To prevent an event due to production of electromagnetic coupling and interference noise when mechanical distance of each device is close to each other by switching plural reference oscillators and driving a load circuit used for all systems depending on the output of any reference oscillator. CONSTITUTION:If a fault takes place in a living set 1-1, an input signal switch 5 and an output signal switch 6 for the system 1 are switched by its fault occurrence signal, an input signal from the system 1 is inputted to a standby set 2 and an output signal of the standby set 2 becomes an output of the system 1. Simultaneously, the reference oscillator output switch 7 is controlled to select the standby reference oscillator 3 and the signal is fed in parallel with each load circuit 4. If a fault takes place in other living sets 1-2 1-N, the standby set 2 is controlled to be selected. Thus, even when each living set and standby set are mounted closely in terms of distance, no beat fault takes place due to the electromagnetic field coupling and interference noise of a low frequency is not superimposed on the output.

Title: Gear clutch mechanism
Inventor: KOSAKAI MASAHIRO
IPC: F16D11/08
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a gear clutch mechanism of high reliability wherein a working pitch diameter of an input gear and a shaft direct connected gear is dislocated so as to be increased/decreased. SOLUTION: An input gear 4 is integrally formed with a timing belt wheel 3, driven and rotated by a timing belt. In order to engage a clutch gear 6 with the input gear 4 and a shaft direct coupled gear 5, when the clutch gear is moved in a direction of arrow mark (p), a shaft 2 is rotated. At this time, a working pitch diameter of the input gear 4 is increased by performing positive dislocation of 0.1 to 0.2 dislocation coefficient relating to the shaft direct coupled gear 5, or a working pitch diameter of the shaft direct coupled gear 5 is decreased by negative dislocation of 0.1 to 0.2 dislocation coefficient relating to the input gear 4. As a result, since meshing of the clutch gear 6 with the input gear 4 is prior to meshing with the direct coupled gear 5 of the clutch gear 6, clutch action without interfering with the respective gears can be performed.

Abstract: PURPOSE:To improve the precision of conversion to multiple levels while keeping the resolution of a reproduced multilevel picture by varying the window size in a prescribed window processing in accordance with the density at the time of conversion from a binary picture into a multilevel picture. CONSTITUTION:A line buffer 1 buffers several-line, for example, 8-line components of the picture and simultaneously supplies data corresponding to plural lines, and the output is inputted to a data adding part 2. The adding part 2 operates and outputs the total sum of several picture elements out of inputted 8X8 picture elements. This output ad1 is the total sum value in the area except a square area A of a square area B, and an output ad2 is the total sum value of picture elements in the area A. An adaptive multilevel conversion part 3 converts outputs ad1 and ad2 into multilevel data. Thus, the degradation of resolution is reduced as much as possible to perform the processing at the time of inverse conversion from binary picture data into multilevel data.

Title: Combustion apparatus
Inventor: MORIGAMI KAZUHISA
IPC: F23C6/04
Filed: 1993-09-16
Abstract: PURPOSE:To elongate the service life of a catalyst and to reduce odor at the time of ignition or fire extinguishing in a combustion apparatus such as an indoor open type warm-air heater, etc. CONSTITUTION:This combustion apparatus comprises a catalyst 11 arranged out of a rear opening of a duct 9 to purify unburned gas to temporarily pass burned gas through the catalyst 11 at the time of ignition or fire extinguishing of a burner 6. Accordingly, since the burned gas is passed through the catalyst only for a short time of the ignition or extinguishing, the service life of the catalyst is elongated. Since the catalyst having a low activation temperature can be used, an effective odor reducing effect is obtained even when the catalyst temperature is low at the time of the ignition or extinguishing.
