Title: Thermo-sensor
Inventor: KAKINOTE KEIJI
IPC: G01K7/16
Filed: 1989-06-24
Abstract: PURPOSE:To enable a sudden temperature change to be surely detected by mounting a substrate having thin portions on a heat sink and providing the thin and thick parts of the substrate with thermo-sensitive portions. CONSTITUTION:A substrate 1 with a part A having a smaller thickness is mounted on a heat sink 2. Parts A and A' with smaller and larger thicknesses l and l' are provided with thermo-sensitive parts S and S', respectively. When a temperature suddenly rices, the temperature of the part A with the smaller thickness l more quickly increases than that of the part A' with the larger thickness l'. Therefore, a large temperature difference is generated between the parts A and A' with the smaller and larger thicknesses l and l', respectively. Thus, a large signal difference is produced between signals from the parts A and A' with the smaller and larger thicknesses l and l', respectively. Thus a sudden temperature change can be surely detected.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: TAKAYAMA KENGO
IPC: F02D41/14
Filed: 1994-07-13
Abstract: PURPOSE:To prevent the generation of the phase difference of a control value during feedback of an air-fuel ratio at each cylinder group by detecting the control position difference of each cylinder group and correcting a control constant the control period of which is regulatable according to a phase difference. CONSTITUTION:Through feedback control of the air-fuel ratio of each cylinder group, the phase difference of a control value at each cylinder group is produced. Thus, since a phase difference is produced between the detecting values of first and second air-fuel ratio sensors 14 and 15, based on the phase difference of a detecting value, the phase difference of a control value is detected by a control phase difference detecting means. By correcting a control constant the control period of which is regulatable, correction is effected in a direction in which a phase difference is removed through correction of a control period, and a control period is also corrected. In this case, if a control phase difference detecting means is constituted to detect the phase difference of the control value based on a time difference with which the output value of an air-fuel ratio detecting means at each cylinder group passes a reference value and the fluctuation direction of an output value, it is discriminated whether the phase of other cylinder group is an advance phase or a delay phase based on a reference cylinder group and from the phase difference, the magnitude of the phase difference can be determined.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To realize a mesa-type glass-coated semiconductor device with a high withstand voltage, which is coated with lead glass, so as to reduce a leakage current to an extremely small amount, and to obtain high reliability. SOLUTION: An n-type semiconductor region 1 is used as a semiconductor substrate. A p+ type semiconductor region 2 having a high impurity concentration is formed on one main surface of the substrate, and an n+ type semiconductor region 3 having a high impurity concentration is formed on the other main surface of the substrate. Mesa grooves are formed from one of the main surfaces to predetermined regions such that p-n junctions are exposed, and a first insulating film 6 of silicon nitride and a glass film 5 are sequentially formed at the mesa portions. As the silicon nitride film is provided between the glass film and the semiconductor, diffusion of aluminum in the glass into the semiconductor is prevented, and occurrence of a leak current due to a channel current is prevented, thereby the leakage current is reduced.

Filed: 1980-11-19
Abstract: PURPOSE:To reduce the cost of cables and the device and shorten the data delay, by making the frequency of a synchronizing signal of an MODEM higher than the transmission speed of receiving data from a terminal control device, in the data repeater which repeats the synchronizing signal. CONSTITUTION:Receiving data is taken into a bit buffer 48 in bit serial synchronously with the synchronizing signal extracted from receiving data from a terminal equipment 3, and data in the bit buffer 48 is outputted in bit serial synchronously with the synchronizing signal of an MODEM. In this case, the number of bits of the synchronizing signal of the MODEM generated in a one-bit interval of the synchronizing signal extracted from receiving data is monitored; and if <=2 bits are detected, an rseudo flag sequence is inputted to the bit buffer 48 just after receiving of a flag sequence from the terminal equipment to prevent the error of receiving data from the terminal equipment 3. Consequently, since the synchronizing signal of the MODEM is not supplied to the terminal equipment 3 and data is not subjected to serial-parallel conversion, the cost of cables and the device is reduced, and the data delay is shortened.
