Title: Brushless motor
Inventor: SHIRAKAWA KUNIICHI
IPC: H02K29/08
Filed: 1989-12-26
Abstract: PURPOSE:To enable a position detecting means to be directly attached to a circuit board so as to dispense with the connection by a lead between the position detecting means and the circuit by enabling the magnetic flux of a rotor to be transmitted to the position detecting means through a magnetic substance, and providing a housing with a position detecting means on the opposite side to a stator and a rotor. CONSTITUTION:This is equipped with a stator 14, a rotor 24, which is provided on one side of a housing 10, a position detecting means (hole element), which is provided on the other side of the housing 10 and detects magnetically the rotational position of the rotor 24, and a magnetic substance 36, which is provided piercing the housing 10 and one end of which is connected magnetically to the hole element 34 and the other end of which is arranged close to the rotor 24 so that it may transmit the magnetic flux of the rotor 24 to the hole element 34. That is, since the magnetic flux of the rotor 24 can be transmitted to the hole element 34 through a magnetic substance 36, the hole element 34 can be arranged on the opposite side to the stator 14 and the rotor 24 for the housing 10. Hereby, the hole element 34 can be mounted directly on the circuit outside the housing 10, so the connection by a lead wire becomes needless.

Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal device wherein a liquid crystal driving IC or the like can surely be prevented from being damaged during operation of mounting a polarizing plate or the like on the substrate of the liquid crystal panel. SOLUTION: This is a liquid crystal device constituted by mounting an IC chip 16 on one of a pair of substrates 2a, 2b interposing a liquid crystal 14 in-between, and a thickness H2 up to the height of the IC chip 16 is set to be thicker than a thickness H1 up to the adjoining substrate 2b, but is set to be equal to or thinner than the thickness H3 up to a phase difference plate 10 mounted on the substrate 2b and the thickness H4 up to a polarizing plate 11. Since the thickness up to the phase difference plate 10 or the like is thicker than the thickness up to the IC chip 16, when the 2nd substrate 2b side is mounted on a base part to perform operation of mounting a polarizing plate 11a on the 1st substrate, it is surely possible to prevent the IC chip 16 from being abutted on the base part and prevent excessive force being applied to the IC chip 16.

Title: Assembled battery charge controller
Inventor: ISHIKAWA YASUTAKE
IPC: H02J7/14
Filed: 1994-12-29
Abstract: PURPOSE: To efficiently charge batteries for forming assembled battery at the time of regenerating a motor. CONSTITUTION: When the regenerating operation of a motor 7 is started, unit cells are charged by currents flowing from an inverter 6 to an assembled battery. When the terminal voltage of any of the cells exceeds an overvoltage detection level, a monostable multivibrator 101 is triggered via an OR circuit 21 to output a positive pulse signal. A braking transistor Tr2 is not turned on while the pulse signal is output, and the terminal voltage of the each cell is continuously raised. When the signal is not output, the transistor Tr2 is turned on, and a current from the inverter 6 flows through a braking resistor R9. Thus, even if the terminal voltage of the cell is lowered by the voltage drop of the internal resistance of the cell at the time of finishing the regeneration of the motor 7, the terminal voltage of the cell is not almost lowered as prior art.

IPC: G01S17/08
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To obtain a range finder having a small size, light weight and high detecting accuracy by providing first and second deflectors for deflecting transmitted and received laser beams in specific directions. SOLUTION: The transmitted laser beam LT output from a light emitting unit 7 is reflected in the upper axis direction of a rotary shaft C by a first mirror M1, the beam LT is incident on a first deflector A1 rotating at the shaft C as a center by a motor 10, deflected in the downward oblique direction to the shaft C to emit a target, and conically scanned to rotate it. The received laser beam LR of the reflected light of the target is received by a second deflector A2 rotating integrally with the deflector A1, deflected in the lower axis direction of the shaft C, reflected by a second mirror M2 and incident on a light receiving unit 8.  Thus, since the range finder L1 continuously measures in a circular shape, the detailed measurement of the uneven part of the target can be conducted, and since the simple structure of one light emitting unit 7 and light receiving unit 8 is adopted, the range finder becomes a small size and light weight.
