Abstract: PURPOSE:To make assist control performable at the safety side irrespective of any trouble in a torque sensor by controlling a driving current of an electric motor according to a low level torque value among torque values or output of plural numbers of torque sensors detecting steering torque. CONSTITUTION:A torque value T in use on assist control is determined on the basis of respective torque values T1, T2 being detected by two torque sensors 5, 6 but at time of this determination, first the second torque value T2 is compared with a minimum torque value Tmin and a maximum torque value Tmax in a normal range, and then the absolute value of a difference between both these torque values T1 and T2 is compared with a maximum error DELTAT of both torque values. When it is so judged that there is no trouble from these compared results, the absolute values of both torque values T1, T2 are compared, and the low level torque value is determined as the torque value T. Then, a steering assist value is operated from this determined torque value T and a car speed V by a car speed sensor 21, thereby driving and controlling an electric motor 8.

Title: Light deflector making use of standing wave
Inventor: OTANI AKIHITO
IPC: G02B26/10
Filed: 1984-12-27
Abstract: PURPOSE:To permit deflection at a high frequency (several hundreds kHz) and to make controllable the deflection direction as well by an electric signal by the constitution consisting in changing the direction of light by a piezoelectric element which can control oscillation by an electric signal and the standing wave of a reflecting mirror induced by the oscillation. CONSTITUTION:The piezoelectric element 2 itself repeats the elongation or contraction corresponding to the electric signal when the electric signal is applied between the 2nd electrode on said element and the 1st electrode 8 on a substrate. The oscillation is eventually transmitted to the reflecting mirror 4 fixed to the upper part of the element 2 and the standing wave is generated in the reflecting mirror as the reflecting mirror is supported on one side, i.e., in the cantilever state and as the elongation and contraction of the piezoelectric element are of a high speed (several hundreds kHz). The standing wave repeats periodically as the function of time. The angle direction of the reflecting mirror changes consequently with respect to the incident light made incident from a certain specified direction. The deflector of the light of which the incident angle changes with time and the direction of the light reflected by the specular surface changes is thus obtd.

Title: Snow-melting system utilizing unused heat source
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/06
Filed: 1994-10-13
Abstract: PURPOSE: To secure the capacity of snow melting by a method wherein a system is made to work as a heat pipe in the case of preventing freezing on the road surface or melting snow in a small amount while thermal energy is supplied from a low- temperature unused heat source with a compressor and an expansion valve operated in the case of meeting snow in a large amount. CONSTITUTION: Normally the system is operated as a heat pipe, and the snow-melting is made with thermal energy from an unused heat source transmitted as vaporization latent heat for working fluid. In the case where snow is melted in a large amount in a condensation part 2, the working fluid is made to run through a bypass passage, and the working fluid vaporized in a vaporization part 1 is compressed with a compressor 10 and internal energy thereof is increased. Therefore, mechanical energy given to the working fluid by the compressor 10 is discharged as thermal energy. When the working fluid is in the bypass passage, running therethrough, the heat pipe is in reversed Rankine's cycle.  Therefore, the working fluid in the condensation part 2 is made higher in temperature and pressure as compared with the case of operation as a normal heat pipe while the working fluid in the vaporization part 1 is made lower in pressure. Thereby, vaporization and condensation are accelerated, and the efficiency in transmission of heat can be improved.

Title: Bar code printing method by thermal head
Inventor: NAKAMOTO AKIRA
IPC: B41J2/36
Filed: 1986-11-18
Abstract: PURPOSE:To extend the life of a thermal head by protecting a heat generating resistor from thermal destruction without losing printing quality, by a method wherein the input energy to the heat generating resistor of the thermal head is changed so as to be reduced with the elapse of time and the heat generating resistor is driven so that the temp. thereof does not exceed rated temp. CONSTITUTION:When the count value of a counter 19 is N, the output pulse Po of an oscillator 13 is applied to a drive circuit 12 as it is but, when said count value becomes (N+1), a pulse width is altered to l2 shorter than l1 and made shorter similarly there after to be outputted. That is, the pulse width applied to a thermal head 1 is controlled in accordance with the count value of the counter 19 through the drive circuit 12. Since input energy is gradually reduced than before on and after the count value N of the counter 19, the temp. of the heat generating resistor 19 of a thermal head 1 at a terminal position H can be set to rated temp. or less and the heat generating resistor 19 can be protected from thermal destruction. Since the heat generating resistor is driven before the count value N by the pulse width l1 capable of obtaining necessary printing density, the printing quality immediately after the start of bar code printing is not deteriorated.

Title: Lid structure for bath tub
Inventor: KATO MASAO
IPC: F24H1/00
Filed: 1986-11-20
Abstract: PURPOSE:To provide a solid and highly heat-insulating lid for bath tube while adding washing function to the main body of a lid structure for bath tube by providing, in the lid structure that is formed in a box shape, a water-jetting water wheel which jets out cleaning water by the pressure of the water, a solenoid valve which opens and closes the water flow to a pressurizing pump according to the output of a water level switch, and an accumulator. CONSTITUTION:The water flowing in from a tap water faucet enters a pressurized pump 9 in the open state of a solenoid valve 10 from a supply water opening 8a, and the pump pressure is added to the pressure of the tap water then the tap water enters a two-way switching valve 6. If this two-way switching valve 6 is switched to the water for a water jetting water wheel 4, it jets out high pressure water and rotates. The high pressure water that is jetted out hits a bath tub lid structure which becomes the wall and ceiling of the bath tub and gives cleaning effect for them. If the two-way switching valve 6 is switched over to a supply water opening 6b by closing a water draining plug 3, the water flow or hot water flow enters the inside of the bath tub, and when it is full, a water level switch 7 detects the water level and closes the solenoid valve 10 and at the same time stops the pressurizing pump 9. Since normally water hammer is generated on the tap water side by closing the solenoid valve 10, and noises occur in the piping section, so the expansion of an accumulator 8 is utilized to absorb the noise.
