Title: Torque transfer controller for four wheel drive vehicle
Inventor: MATSUMOTO YASUHEI
IPC: B60K17/348
Filed: 1986-02-28
Abstract: PURPOSE:To make a controller perform control over torque transfer according to clutch hydraulic pressure as well as to optimize the torque transfer to both front and rear wheels with each driving condition, and make improvements in turnability and safety, by installing two sets of planetary gears and two sets of hydraulic clutches in combination in the point midway in a front-rear wheel driving system. CONSTITUTION:Two sets of planetary gears 30 and 35, in the same structure, for center differential gear use are installed in the point midway in a front-rear wheel driving system, and constituted of sun gears 31 and 36, ring gears 32 and 37, pinions 32 and 38 to be engaged with these gears, and carriers 34 and 39. And, the sun gear 31 is connected to a rear wheel shaft 19 via a gear 23 and the sun gear 36 to a front wheel shaft, respectively. Thus, a rotational difference between front and rear wheels is absorbed by planetary rotation of these pinions 33 and 38. And, a hydraulic clutch 40 is connected to an interval between the ring gear 37 and the sun gear 36 and a hydraulic clutch 45 to an interval between a gear 22 and the rear wheel shaft 19 respectively, thus these clutches are installed. Then, a torque transfer signal corresponding to a driving condition is outputted to actuators 55 and 56 from a control unit 54, and hydraulic pressure in these hydraulic clutches 40 and 45 is altered, whereby torque control takes place.

Title: Heat sensor
Inventor: WADA TAKETSUGU
IPC: G08B17/06
Filed: 1989-02-23
Abstract: PURPOSE:To increase detecting accuracy by successively storing temperature data into a storing means, and issuing an alarm signal when the difference between the newest temperature data and the stored temperature data exceeds a prescribed value. CONSTITUTION:A heat sensor 1 detects the temperature at a set place by a temperature detecting means 12, converts the temperature into an electric signal, and outputs it to a signal processing means 11. The means 11 fetches the electric signal in a prescribed cycle, processes the signal, and processed data are stored into a storing means 13. The means 11 successively obtains the difference between the newest data and the plural data stored up to a present time out of the data stored into the means 13 whenever the data are stored into the means 13, and when the difference exceeds the prescribed value, the sensor judges abnormality, and outputs a discriminating signal to a switching means 14. The means 14 short-circuits a power source circuit 10, and outputs the alarm signal to a fire receiver. In such a configuration, when the temperature rise over the set value is generated, the alarm signal can be surely issued.

Title: Electronic device
Inventor: TAKEUCHI HIROTOSHI
IPC: H03K17/22
Filed: 1986-02-28
Abstract: PURPOSE:To decrease power consumption and to prevent the adverse effect onto the service life by changing a reset decision voltage of a reset circuit synchronously with on/off of a load and lowering a reset decision voltage when a voltage of a brute DC power supply is low so as to eliminate the need for setting a reset voltage as required. CONSTITUTION:A transistor 7 is turned on/off to control the on/off of a load 6. Then a means 11 changing a reset decision voltage is controlled synchronously with on/off of the load 6 to change the reset decision voltage of a reset circuit 8. That is, when the load 6 is set (when an output of a control circuit 9 is low), the voltage of the brute DC voltage section 4 is lowered, and the transistor (TR) is turned off, a TR B is turned on, a TR C is turned off to set the control circuit 9. Thus, the reset decision voltage is lowered in this way to make the reset voltage when the load 6 is set nearly coincident with the reset voltage when the load 6 is reset.

Filed: 1992-03-02
Abstract: PURPOSE:To obtain an alarm clock which does not sound unnecessary alarms and can awake its user even when the user is a little outside of the human body detecting extent of the clock. CONSTITUTION:When a human body detection circuit 3 detects no human body at alarming time, a control circuit 6 sounds an alarm by outputting an alarming sound generating signal and sets a timer circuit 4. When an alarm setting switch is not opened and the circuit 4 counts five to ten seconds, the circuit 6 stops the sounding of the alarm. When the switch 5 is not opened and the circuit 4 counts about four to five minutes without detecting any human body thereafter, the circuit 6 again sounds the alarm by outputting the alarm sound generating signal and resets the circuit 4. When the switch 5 is not opened and the circuit counts about five to ten seconds, the circuit 6 stops the sounding of the alarm and clears the circuit 4.

IPC: G01N33/36
Filed: 1987-02-27
Abstract: PURPOSE:To permit sure detection of a conductive material by providing a through-hole to the central part of a re-entrant cylindrical cavity resonator connected to a microwave oscillator, passing a specimen which is a nonconductive fier into the through-hole and discriminating the change in resonance conditions. CONSTITUTION:The through-hole 12 into which yarn 13 is passed is provided to the central part of the re-entrant cylindrical cavity resonator 11 and the resonator 11 is connected via an input/output terminal 23 mounted on the outside wall part thereof and a circulator 24 to the microwave oscillator 16. The output of the resonator 11 is supplied via an A/D converter 26 to a CPU 18; on the other hand, the output for controlling the oscillation frequency of an oscillator 16 is transmitted via a D/A converter 27. The amplitude of the output does not change and the resonance frequency shifts largely when there is a very small metal in the yarn 13; therefore, whether the conductive foreign matter is moisture or metallic foreign matter is identifiable if the discrimination as to whether the output drop of the resonator 11 is by a change in the resonance frequency or is the mere change in the amplitude is made.

Title: Formation of layer insulating film
Inventor: KURODA HIDEAKI
IPC: H01L23/522
Filed: 1993-02-09
Abstract: PURPOSE:To increase an yield by forming a flat layer insulating film and by preventing the breaking of voids in the following high-temperature treatment. CONSTITUTION:After a bit line is formed with a tungsten polycide film 51, an SiO2 film 52 is deposited and then a polycrystalline silicon film 75 is deposited by vacuum CVD. After that, the polycrystalline silicon film 75 is isotropically etched back to fill a recessed section 55 with the polycrystalline silicon film 75. Under this condition, a BPSG film 56 is deposited. Since the polycrystalline silicon film 75 formed by vacuum CVD has an excellent step coverage, the generation of voids can be prevented. Furthermore, when the polycrystalline silicon film 75 is etched back, the SiO2 film 52 serves as a stopper.

Title: Film joint method for packer or the like
Inventor: NO CHUJI
IPC: B65H19/18
Filed: 1986-02-28
Abstract: PURPOSE:To make it possible to suitably cope with a delay in rise of a film even during high speed conveyance, by providing a movable accumulation roller between a splice roller and a feed roller between which the film is conveyed. CONSTITUTION:When a film 3 on running is jointed with a stand-by film 3a, even through the stand-by film 3a is not paid out from a roll 2a at once, if the running film 3 which has been replenished by means of an accumulation roller 10 during that period, is fed to feed rollers 5, 5, it is possible to feed the film at a predetermined speed even after completion of joint. Further, the pay-out speed of the stand-by film 3a is set so that the speed of the film 3 on travel becomes substantially equal to the speed during the roller replenishing the film. Thus, when the supply of the film by the retraction of the accumulation roller is completed, no delay in rise of the stand-by film occurs, thereby it is possible to maintain the feed speed of the film constant.
