Title: Torque control system for tractor
Inventor: MUKAI NAKASHIRO
IPC: F02D29/00
Filed: 1988-09-19
Abstract: PURPOSE:To facilitate a smooth speed control by controlling the controlling divergence of an accelerator pedal so as to be not less than the controlling divergence of a throttle lever, and changing the engine output in the part having this higher controlling divergence to a torque characteristic having a small coefficient of variation. CONSTITUTION:The controlling divergence of an accelerator pedal 2 is controlled so as to be not less than the controlling divergence of a throttle lever 1, and the output torque of an engine 3 in the part having this higher controlling divergence is automatically changed by a torque control device 4 from the torque characteristic corresponding to a load to a torque characteristic corresponding to the running having a small coefficient of torque variation. This change reduces such a shock as making a vehicle body 5 jerk, and a smooth turning drive can be carried out by controlling the speed properly.

Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide the communication method for ciphered information high in security and easy in operation. SOLUTION: A sender terminal equipment 201 uses system key information sent from a ciphering processing server 30 on request to send a ciphered information signal obtained by ciphering message information to a terminal equipment 20n of the transmission destination.

Title: Running control device for vehicle
Inventor: MIYAMOTO YASUHIKO
IPC: B60K17/10
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To provide excellent running performance without exerting an excess load on a prime mover even when a load during running is changed. SOLUTION: In a control means 19, based on a pump oil pressure detected by an oil pressure sensor 17a or 17b located in the oil pressure route 6f of a hydrostatic continuously variable transmission 6, a pump flow rate of a hydraulic pump 6c arranged at the hydrostatic continuously variable transmission 6 is set. Provided an absorption horse power exerted by the engine of the hydrostatic continuously variable 6 is PS, a pump oil pressure is P, and a pump flow rate is Q, a relation of PS=P.Q/η (η is total efficiency) is established.  Since the pump oil pressure P is a value fluctuated according to the suction load of the hydrostatic continuously variable transmission 6, when the suction horse power PS is kept at a constant value, by setting the pump flow rate Q to a value inverse proportional to the pump oil pressure P, a running vehicle is reasonably run in correspondence to a load fluctuation without exerting an excess load on the engine. 1%'.

Title: Display device
Inventor: YOSHINAGA KAZUO
IPC: G02F1/1335
Filed: 1990-09-10
Abstract: PURPOSE:To obtain a high reflection factor and an excellent contrast by reflecting circular polarized light, made incident on a display layer, by a reflecting layer and separating the projected circular polarized light by a specific means. CONSTITUTION:When the means which consists of a polarizer (plate) 8 and a 1/4-wave length plate 9 and generates the circular polarized light is used, the linear polarized light of the incident light 10 obtained by the polarizer 8 is made incident on the 1/4- wavelength plate 9 at 45 deg. to become the circular polarized light. This circular polarized light is made incident on the display layer 3 which contains a high polymer liquid crystal compound oriented in a uniaxial direction so as to have an angle theta to the linear polarized light to become the linear polarized light, which is reflected by the reflecting layer 2a. This reflected light 11 is projected as circular polarized light by passing through the display layer 3 and the contrast is obtained by the means which separates clockwise and counterclockwise polarized light beams. In this case, the axis of polarization of the polarizing plate and the axis of orientation of the display layer are preferably at 35 - 55 deg.. The incident linear polarized light does not become complete circular polarized light outside the range of 35 - 55 deg. and leak light is generat ed, so the contrast decreases, which is not desirable. The angle is preferably 45 deg. for use.

Title: Waveform correcting device for input signal
Inventor: SUZUKI MASAMICHI
IPC: G11B20/10
Filed: 1989-09-14
Abstract: PURPOSE:To optimumly correct the waveform of an input signal even when the waveform of the input signal is made various by providing plural delay means with various delay amounts and a means to switch the plural delay means based on the waveform of the input signal, in a delay signal output part. CONSTITUTION:When the input signal is inputted, a delay signal output part 1 outputs this input signal while being delayed based on the delay amount of a delay means 3-1, for example, so as to satisfy the input signal in any waveform at a minimum. A waveform correcting part 2 synthesizes the input signal with the signal outputted from the output part 1 and attenuates the signal to be a correcting signal. According to the waveform of this correcting signal, the input signal is corrected and outputted. However, when the input signal with the waveform different from the above mentioned input signal is inputted, in the output part 1, the waveform of this input signal can not be optimumly corrected by the delay means 3-1 and accordingly, a delay amount switching means 4 switches the delay means from the delay means 3-1 to delay means 3-2 - 3-n with the various delay amounts.

Title: Leakage current measuring apparatus
Inventor: FUJII TOMOHIRO
IPC: H01H69/01
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To enable easy judgment of whether a leak detector is operating normally or not by providing a means to hold an instantaneous leakage current value as maximum value when the leak detector outputs a detection signal. SOLUTION: When a leak detector 3 detects a leakage current, a signal is outputted from an external output 4, and the value of the leakage current measured by a measuring section 2-1 is held as maximum value by a maximum value holding means 2-2. Therefore, this maximum value is an instantaneous leakage current value when the leak detector 3 is starts to work. A display means 2-3 displays the instantaneous leakage current value and the maximum value. When the leak detector 3 starts to work, a person in charge of inspection reads the maximum value from the display means 2-3 and compares the value with an action sensitivity value of the leak detector 3. When the value is smaller than the action sensitivity value, the person in charge can judge that the leak detector 3 malfunctions.  When the value is larger than the action sensitivity value, he can judge that the leak detector 3 operates normally and also can learn the state of leakage by reading the instantaneous leakage current value.

Abstract: PURPOSE:To restrain the temperature rise of intake gas for improving the efficiency of a compressor by mounting an insulation member on the peripheral wall of an intake pipe for introducing gas from the outside of a pressure container into the cylinder of a compression mechanism. CONSTITUTION:An insulation pipe 21 is formed into a double layered cylinder having its outer peripheral surface making contact with the inner peripheral surface of an intake pipe 16 so that refrigerant gas flows into the inside of the pipe 21 and a cylinder 9 through the intake port of the cylinder 9. By supplying current to the stator 2 of a vibrator section A, the refrigerant gas sucked from the intake pipe 16 is compressed by a compression mechanism section B to provide high temperature and pressure gas exhausted through a discharge pipe 17 to the outside of a pressure container 1. Then, heat transmitted from the pressure container 1 and respective components therein to the intake pipe 16 is screened by the insulation pipe 21 to reduce the heat transmitted to the refrigerant gas in the intake pipe 16, so that the temperature rise of the refrigerant gas is restrained. Thus, the intake gas heating loss is reduced to improve the efficiency of compression.
