Filed: 1986-02-03
Abstract: PURPOSE:To detect the magnetizing signal of a rotor magnet with high precision by extending the projection of a Hall element while by lengthening input/output terminals rather shorter than the projection and by bringing the Hall element close to the rotor magnet. CONSTITUTION:A Hall element 1 is composed of an envelope 13 made from resin, the Hall element body itself, and a cylindrical projection 12 provided in the center of its bottom surface and four (4) pieces of input/output terminals 11 made of metal. The projection 12 is extended long and the four (4) pieces of input/output terminals 11 are lengthened rather shorter than the projection 12 in the extended direction of the projection 12 and in the same length for all the four (4) pieces. This Hall element is positioned by inserting into a fitting hole 10 of a stator 5 of a brushless motor. As the bottom surface of the Hall element gets in the floating condition from the surface of the stator 5 while the envelope 13 enclosing the flux detecting portion comes closer to the magnetized surface of a rotor magnet 2, the information on magnetization by the rotor magnet 2 can precisely be detected.

Filed: 1988-02-03
Abstract: PURPOSE:To improve the operability of the title timepiece by providing an input means which performs up-down corrections of area zones independently of one another with switches A and B and a gate means which performs different functions when the switches A and B are operated at the same time. CONSTITUTION:When a switch A1 is turned on, a chattering preventing circuit 4 shapes a waveform and then the time counters in an area zone counter 7 and a time counter 6 are increased by one. Their counter values are decoded by a display circuit 8, the illumination segments of an area display indicator 10 shift by one, and the time is advanced by 1hr. Consequently, the up correction is made with the switch A and each counter is decreased by one with the switch B as well to make a down correction. Thus, an ON signal becomes the up-down correction signal of the counter directly, so the operate independently regardless of the on-off operation of the other switch. Further, an AND gate 3 detects simultaneous input and another function is commanded with its output. Therefore, the correcting operation is easy and said different functions can be added without increasing the number of switches.

Title: Printing cylinder cleaning device
Inventor: TATEISHI HARUMOTO
IPC: B41F35/06
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To supply a cleaning solution by spraying to the contact part of a wiping cloth in the longer direction equivalent to the cylindrical length of a cylinder on the printer by providing a first pressure chamber which receives the cleaning solution from a cleaning solution supply means on a cleaning solution supply pipe and at the same time, a second pressure chamber which receives the cleaning solution from the first pressure chamber. SOLUTION: A cleaning solution supply pipe is equipped with a first pressure chamber 42 which receives a cleaning solution from a cleaning liquid supply means and at the same time, is equipped with a second pressure chamber 44 which receives the cleaning solution from the first pressure chamber 42, and a cleaning solution supply nozzle 46 is mounted on the second pressure chamber 44. The cross section of the first pressure chamber 42 is such that the inner depth side is smaller than the inlet side. The cleaning solution finding its way into the first pressure chamber 2 flows to the inner depth side passing throuhg first holes 48 from the inlet side of the first pressure chamber 42, while being supplied to the second pressure chamber in turn.  In this case, the flow rate of the cleaning solution is almost constant as the cross section of the first pressure chamber 42 becomes smaller from the inlet side to the inner depth side and therefore, the cleaning solution can be supplied to the second pressure chamber 44 at almost a constant flow rate. Thus it is possible to supply the cleaning solution by spraying uniformly in the longer direction equivalent to the cylindrical length.

Filed: 1990-02-02
Abstract: PURPOSE:To minimize the degree of fatigue of a user and to improve the operability by taking out a variation of depressing pressure or a depressing stroke applied to a button switch as a digital signal of plural bits. CONSTITUTION:When the left button switch 6A is depressed, depressing pressure is applied to pressure sensitive conductive rubber 13A through a slider 10A, a depressing spring 11A and a depressing body 12A, and the resistance value of the pressure sensitive conductive rubber 13A is varied. As a result, a voltage corresponding to the depressing pressure can be obtained in the other end of a resistance 17A, that is, the input terminal of an A/D converting circuit 18A. Also, the A/D converting circuit 18A converts a voltage value obtained by a depressing pressure detecting means 23A to digital signals B0-B2 of a 3-bit binary format, that is, divides the voltage value into eight pieces of levels, and transfers it to a control part 19. In such a way, the degree of fatigue of a user can be minimized, and also, the operability can be improved.

Title: Four-wheel steering device for vehicle
Inventor: MIYOSHI AKIHIKO
IPC: B62D6/00
Filed: 1986-02-07
Abstract: PURPOSE:To prevent the sudden change of a rear wheel steering ratio when said rear wheel steering ratio suffers an extreme change and improve safety by providing an actuator for adjusting said rear wheel steering ratio and an operating speed limiting means for restricting the maximum value of the operating speed of said actuator to a defined value. CONSTITUTION:The captioned device has an actuator for adjusting a rear wheel steering ratio and an operating speed limiting means of restricting the maximum value of the operating speed of the actuator to a defined value. Thereby, since the defined maximum value is set to the operating speed of the actuator, even if the steering ratio suffers an extreme change, the accompanying steering ratio changing speed does not become above the defined value. Accordingly, since the steering ratio changing speed is restricted by the maximum value which is set to the operating speed of the actuator, when the rear wheel steering ratio suffers an extreme change, a sudden change of the steering ratio, i.e., the sudden change of the behavior of a vehicle can be prevented improving safety.
