Title: A/d converter
Inventor: ITO MASAO
IPC: H03M1/36
Filed: 1993-03-01
Abstract: PURPOSE:To detect an accurate rough voltage range and to obtain the accurate conversion data by inhibiting a fine voltage supply means from supplying the fine reference voltage to a range detecting means by a fine voltage supply inhibiting means in a rough comparison period. CONSTITUTION:The control signal 2 obtained from a timing signal generator 5 is kept at a high level in a fine comparison period only. A gate circuit 7 outputs the switching control signals S11'-S14' received from an encoder 3 as the new control signals S11-S14. In a rough comparison period, the switching circuits 11-14 are tuned off in response to the signals S11-S14 given from the circuit 7. Thus the fine comparison voltage is not given to the voltage comparators 21-23. Therefore the signals S11'-S14' which turn on two or more of the circuits 11-14 are not applied to the circuits 11-14 as the control signals in the rough comparison period when a multi-address is generated at an A/D converter 100. Thus a comparing operation is carried out with the use of the correct rough comparison voltage.

Title: Turning device of vehicle's seat
Inventor: MUTOU TADASHI
IPC: B60N2/90
Filed: 1982-03-15
Abstract: PURPOSE:To enable a seat to make smooth lateral sliding toward the aisle in assolication with turning of the seat with the aid of cooperative motion of stationary rollers and a rolling cam which has rotatably rollers at its four corners by disposing said cam under a turn disc which supports the seat body. CONSTITUTION:When a clockwise turning force for instanse, is applied to a turn disc 7 which supports a seat body, the contact pressure at the contact point is increased between a rolling cam which is disposed beneath the turn disc 7 and consists of cam metal 10 and rollers 11 and a stationary roller 13 which is disposed at a base frame 1. The stationary roller 13 therefore acts as a fulcrum and the rolling cam is subjected to a moment reaction force so that a sliding frame 2 which supports the turning disc 7 is laterally shifted along a U-shape groove 4 on the base frame 1 against the load of a spring 14. The lateral sliding is inverted at a point where the rolling cam is turned by 45 deg. and when the rolling cam makes further turn of 90 deg., it is returned to the original position. The sliding frame is thus reciprocated at a cycle of the turning angle of 90 deg..

IPC: G01B11/02
Filed: 1983-03-10
Abstract: PURPOSE:To obtain an optical scale reading apparatus simple in constitution, good in operability and having ultra-high resolving power, by a mechanism that a reflective type scale is used as a scale and laser beam incident to the scale is enlarged while 90 deg.-phase difference is formed by utilizing beam phase delay by the reflection of a half mirror. CONSTITUTION:The output beam of a semiconductor laser 21 is incident to a scale 23 through a lens 22. + or - primary diffraction beams are reflected by mirrors 24, 25 and, after passed through a half mirror 26, mixed and interfered by a second half mirror 27. The beams from the mirror 27 are converted to electric signals by light receiving elements 28, 29. The phase difference of the signals at the light receiving elements 28, 29 is determined only by the phase delay by the reflections of - primary diffraction beam and + primary diffraction beam at the half mirror 27 while the phase delay is determined by the incident angle of the incident beam and the angle of a polarization surface. When the polarization surface is parallel to the incident surface, the incident angle is 75 deg. while the outputs of the elements 28, 29 come to sine waves having phase difference of 90 deg. and, by analogue interpolation, ultra-high resolving power is obtained.

Abstract: PURPOSE: To increase the magnetic flux density of synthetic magnetic flux of magnetic flux owing to field magnetic poles and magnetic flux owing to an armature and thereby increase torque by setting the positions of brushes a specified angle ahead of a geometric neutral axis in the rotation direction of the armature. CONSTITUTION: The positions of brushes 6a, 6b are so set that a straight line D-D' connecting the centers of the brushes 6a, 6b may lead a straight line C-C' running between field magnetic poles 2a, 2b by a specified angle θ in the rotation direction of an armature 4. The angle of lead θ of the brushes 6a, 6b should be in a range of O<θ<(180 deg./P-θp/2), where θp is a polar arc angle of the field magnetic poles 2a, 2b and P is the number of poles. Owing to this structure, the magnetic flux density of synthetic magnetic flux of magnetic flux of the field magnetic poles 2a, 2b and magnetic flux of the armature increases and thereby torque increases.  Furthermore, the field magnetic poles 2a, 2b are formed from electromagnets and they are so structured that magnetic flux may not leak in some parts around the armatures where the field magnetic poles do not exist. By this method, sparking is prevented from being generated in the brushes 6a, 6b.
