Title: Load state detector of induction motor
Inventor: MATSUO KATSUHARU
IPC: H02P25/04
Filed: 1985-12-13
Abstract: PURPOSE:To accurately detect a signal depending upon a load state such as variation in a torque, a rotating speed by directly detecting a phase difference between a coil current and an applied voltage. CONSTITUTION:A phase detector 8 detects a pulse signal of a time width depending upon the amplitude of a phase difference, i.e., a phase detection signal Vtheta from a motor current detecting pulse voltage Vi and an applied voltage detection pulse voltage Vu. A load state discriminator 13 compares a voltage Vtheta'a divided by resistors 19, 20 from the output thetam of the minimum value holding circuit 23 with an operational amplifier 15, and outputs a state discrimination signal V0 in case of Vtheta'a>Vthetam. A dehydrating timer 24 receives the signal V0, deenergizes a relay 6 after the set time, opens a normal-open contact 7 to deenergize a motor 1. Thus, since it largely varies to the small variation in a rotating speed in a stable range over the rotating speed of the maximum torque point of the phase difference, it can readily and accurately discriminate the fine variation of the rotating speed.

IPC: F02M41/14
Filed: 1991-10-25
Abstract: PURPOSE:To provide an electronic control type fuel injection device in which no false detection of a position sensor due to impact in landing of a plunger occurs even when the plunger jumps up from an inner cam and lands on the inner cam again. CONSTITUTION:A fuel pressure-feeding mechanism 2 is provided with an inner cam 4, on the inner periphery of which a cam surface 3 is formed, a rotating body 6 rotationally driven inside the inner cam 4, and a plunger 5 capable of being freely slid diametrically inside the rotating body 6. With the fuel pressure-feeding mechanism 2, as the rotating body 6 is rotated, the plunger 5 reciprocates in a cylinder chamber 11 to feed fuel under pressure. Since, when fuel is pressure-fed, the plunger 5 jumps up from the inner cam 4, and great impact is applied to the cam-bottom when the plunger 5 lands on the inner cam 4 again, impact cushioning members 24 are provided on the cam- bottom so as to elastically absorb the impact. Thus, the impact of landing of the plunger is transmitted to the inner cam 4 through the impact cushioning members 24.

Title: Information transmitter
Inventor: NEGORO OSAMU
IPC: H04L12/40
Filed: 1989-10-27
Abstract: PURPOSE:To eliminate the useless time of information exchange and to shorten response time by transmitting the response signals of various frequencies for a short time according to the presence and absence of priority information after the lapse of intrinsic interval time by each slave station receiving a simultaneous call. CONSTITUTION:A host station A transmits a simultaneous call code to slave stations B1-Bn by a processor 1. When the slave stations B1-Bn receive the call by a receiver 5, they are set on standby for the intrinsic interval time set for each slave station. After the lapse of the time, the response signals of the various frequencies for each slave station are outputted for a short time according to the presence and absence of the priority information by the respective slave stations. The host station A receives this response signal and decides the presence and absence of the priority information for each slave station in the processor by using a decision clock. Thus, the useless time of the information change is eliminated and the response time can be shortened.

Abstract: PROBLEM TO BE SOLVED: To prevent inside and outside layers from being detached though an interstice is caused between the inside and outside layers due to a difference in the linear expansion coefficient of a constituting material by having a core bar part where plural material layers having a different linear expansion coefficient are laminated at a fixing roller and providing a pull-out preventive part in the direction of a thrust at both ends of the core bar part. SOLUTION: The fixing roller 1 possesses the core bar part 3 where the inside and outside layers 4 and 5 consisting of plural material layers having the different linear expansion coefficient are laminated, and the pull-out preventive part 6 in the direction of the thrust is provided at both ends of the core bar part 3. Then, the inside layer 4 is formed of stainless steel or ferro-alloy whose linear expansion coefficient is small, and the outside layer 5 is formed of aluminum or aluminum alloy whose linear expansion coefficient is large.  Thus, since the pull-out preventive part 6 in the direction of the thrust is provided at both ends of the core bar part 3, the inside and outside layers are not detached though the interstice is caused between the inside and outside layers due to the difference occurring in the linear expansion coefficient of the constituting material at the time of applying and baking a fluorinated resin to a surface at the time of manufacturing the fixing roller.

Abstract: PURPOSE:To reduce the output voltage settling time of a subtractor means by including a preset period between a subtraction period and a succeeding subtraction period and setting a maximum changing voltage of a subtraction output to a half of the voltage for a low level reference voltage range. CONSTITUTION:An analog voltage from a buffer amplifier 9 and an output voltage of D/A converter means 2,8 based on the result of high-level conversion are inputted to subtractor means 10,11 for a 1st operating mode substraction period. Thus, the difference voltage of the both is outputted to a low-level comparison means group 13. Thus, an intermediate voltage VM in a low level reference voltage range is outputted by a prescribed fixed reference voltage from a terminal 16 inputted to the means 10,11 in place of the two inputs as above. Thus, a preset period is included between the subtraction period and the succeeding subtraction period and a maximum change voltage in a subtractor output voltage is set to a voltage a half of the low level reference voltage range applied between terminals 171 and 172. Thus, the settling time of the output voltage of the means 10,11 is reduced.
