Title: Control device for diesel-engine
Inventor: TERASAKA YOSHITSUNA
IPC: F02D29/00
Filed: 1985-10-05
Abstract: PURPOSE:To eliminate a physical disorder feeling and a discomfortable feel in due to abrupt deceleration, by setting a predetermined limit value for the rate of decrease in the amount of fuel injection upon deceleration so that the degree of deceleration is controlled and by changing over the limit value in accordance with the gear shift position. CONSTITUTION:Upon engine operation, after a fuel injection amount computing means 105 computes a fuel injection amount S6 in accordance with a rotational speed signal S2 and an accelerator positions signal S2, a subtracting means 106 calculates a difference S8 between the calculated fuel injection amount S6 and the previous fuel injection amount S7 stored in a hold means 112. Further, in this stage, a limit value setting means 109 sets a limit value S9 in accordance with the output of a gear position sensor 103, and a comparing means 107 compares the value with the above-mentioned difference S8. Therefore, if S8>=S9, the comparing means 107 delivers a high level signal S10. This signal S10 is delivered to an AND means 108 together with a brake actuating signal S5, and this AND means 108 delivers an output to change over a change-over means 110 so that the amount of fuel injection is controlled in accordance with an output signal S12 delivered from a subtracting means 111 for subtracting the signal S9 from the above-mentioned fuel injection amount signal S6 or the signal S7.

Title: Heating element
Inventor: UCHIDA KATSUYUKI
IPC: G03G15/20
Filed: 1993-09-07
Abstract: PURPOSE:To improve heat responsiveness and to decrease variation of temp. in the a radiating part by constituting an insulator between electrodes of a heat generating element as a radiating part. CONSTITUTION:A heat generating element 3 is formed by providing a PTC substrate 1 of a long length having a semicircular cross section with electrodes 2, 2 parallel to each other on both edges in the longer sides of the arc face of the substrate. An insulator 4 comprising a fluorocarbon resin is attached to the area where the PTC substrate 1 is exposed between electrodes 2, 2 which are the heat generating part of the heat generating element 3. This insulator 4 is used as a heat radiating part. Thus, the heating element 5 is obtd. Voltage is applied between electrodes 2, 2 to generate heat from the heat generating element 3 while heat is radiated from the insulator 4 so that a toner applied on a paper sheet by printing is baked and fixed on the insulator 4. In this constitution, since no electrode plate is present between the heat generating part and the insulator 4, the heat capacity decreases. Thus, the heat generating element 3 rapidly responses to the temp. change on the insulator 4, which improves the heat responsiveness.

Title: Quick stop lamp device for automobile
Inventor: NISHI TADASHI
IPC: B60Q1/44
Filed: 1984-10-22
Abstract: PURPOSE:To obviate a collision-from-behind accident, by making irradiating beams pass or intercept to or from both light projecting and receiving parts of infrared rays set up on a floor surface and the opposite position with a foot between, in a way of placing the foot on an accelerator pedal or coming off. CONSTITUTION:When a driver turns on an engine key 6, an electric current flows in a light projecting part 4 and thereby when a light receiving part 3 receives infrared rays irradiated by the light projecting part 4, the current flows in a solenoid switch 7 whereby stop lamps 8 and 8 are lighted by the switch part. Then, when a root is placed on an accelerator pedal 1, the infrared rays are cut off, thus these stop lamps go out. In case of stopping a car, if the foot 2 comes off the accelerator pedal 2, the infrared rays irradiate the light receiving part 3 again, and the current flows in the solenoid switch 7, closing the switch part, and these stop lamps are lighted. Thus, giving advance notice to a succeeding car of the fact that the brake is operated now, and a brake pedal 9 is stepped on. Therefore, these stop lamps 8 and 8 are lighted at that point that the foot 2 comes off the accelerator pedal 1, thus they are yet earlier lighted than ever before.

Title: Semiconductor device
Inventor: MATSUOKA TOSHIO
IPC: H03K19/003
Filed: 1982-12-17
Abstract: PURPOSE:To prevent variation of characteristics of a threshold potential by supplying an inverter circuit which consists of a P and an N channel FET with an input signal through a P channel FET which holds the gate of the inverter circuit at a specific potential. CONSTITUTION:The gates of FETs Q1 and Q2 are connected in common to the source of a P channel FETQ3, the drain of the FETQ3 is regarded as an input terminal, and its gate is connected to a VSS. This FETQ3 clamps the potential applied to the FETs Q1 and Q2. Namely, when the threshold potential of the FETQ3 is Vtp3 and a large voltage is impressed to the input terminal, the input potential to the inverter circuit consisting of the FETs Q1 and Q2 is clamped to -VTpe and never attains to a negative level exceeding it. Further, the threshold potential V1 of the inverter circuit is so set that -Vtp3<Vt<VSS, and -Vtp3 is set so that neither the FETQ1 nor FETQ2 varies in threshold potential. Consequently, the level of the input signal is set except within the range from VDD to VSS, and characteristic variation is eliminated.
