Filed: 1991-02-07
Abstract: PURPOSE:To achieve stabilized operational characteristics of converter by preventing both of torque component current and flux component current from going to zero in an AC motor controller wherein deficiency of field flux produced by the field current is compensated with the flux component current of armature current. CONSTITUTION:A switch circuit 12 is inserted into a circuit for feeding a field difference ef from an operating unit 10 in a field current control system to an operating unit 5 in an armature current control system. When the absolute value ¦iq¦ of an actual torque component current iq obtained from an absolute value circuit 14 drops below a zero torque component current decision value eiq, a comparator 13 functions to turn the switch circuit 12 OFF. Consequently, a field current reference id** is employed, as it is, as a field current reference id* and thereby both of the torque component current and flux component current are prevented from going to zero, resulting in smooth switching operation of positive and negative converter groups in a cycloconverter.

Abstract: PURPOSE:To prevent the generation of a buckling, by using a material the thermal expansion coefficient of which is smaller than that of seal diaphragms at a diaphragm joint part of a body to join both components under a high temperature than the maximum application temperature of this sensor. CONSTITUTION:A fluid pressure Pa and Pb introduced from a pressure introduction port 11a and 11b are transmitted to one side and the other side of a pressure sensitive element 4 through seal diaphragms 3a and 3b and sealed liquid 9a and 9b and a pressure difference being detected is converted to an electronic signal with the pressure sensitive element 4 to be taken outside through a preamplifier 7 or the like. Then, the diaphragms 3a and 3b are made up of an amorphous alloy while the body 2 is made of invar or the like with a thermal expansion coefficient smaller than that the amorphous alloy and as the jointing of the both is performed under a temperature condition, slightly higher than the maximum application temperature of a differential pressure transmitter, contraction of the body 12 is always smaller than that of diaphragms 3a and 3b. Therefore, a radial tension always working on the diaphragms 3a and 3b eliminates the possibility of buckling.

Title: Paper sheets feed mechanism
Inventor: OKUBO KIMIHISA
IPC: B41J13/10
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To positively prevent skew feed of paper sheets and the generation of a jam. without causing enlargement of a device. SOLUTION: In a thermal printer 1, inclined faces 6 are formed at both ends in an orthogonal direction to a feeding direction of an insert guide 4 near a paper outlet 5b of an insert part 5. When a recording medium P is fed upward from the paper outlet 5b toward a space between a platen 7 and a thermal head 8, parts near both ends, orthogonal to the feeding direction, of the recording medium P come in contact with the inclined faces 6, and the parts near both ends orthogonal to the feeding direction are deformed upward and curved in a state of being protruded onto the lower face side. The recording medium P is therefore moved easily to the upper face side so as to be introduced into a position sufficiently spaced from the thermal head 8 between the platen 7 and thermal head 8.  Frictional resistance acting upon the recording medium P from the thermal head 8 moved onto the platen side at the time of printing is therefore reduced so as to be able to prevent skew feed or the like of the recording medium P.

The resultant mixture consists of two layers of an aqueous layer and the halogenated hydrocarbon layer, and the d- and l-isomers without forming the complex are separated from the aqueous layer to separate the d- and l-isomers from the complex dissolved in the halogenated hydrocarbon. Thus, the optical resolution of the aimed benzothiazepine derivative expressed by formula II is carried out.

Title: Optical disk reproducer
Inventor: HAYASHI HIDEAKI
IPC: G11B7/09
Filed: 1985-01-31
Abstract: PURPOSE:To detect the drop-out of the flaws on an optical disk by projecting two light beams on he tracks of the optical disk to extract differentially these reflected signals and then adding those two reflected signals together. CONSTITUTION:The low frequency components are amplified by preamplifiers A1 and A2 for the reflected beams of the beams S1 and S2 detected by the 1st and 2nd photodetectors PD1 and PD2C and supplied from an optical pickup. Then outputs i and ii are delivered from both amplifiers A1 and A2. When these outputs i and ii are supplied to a differential amplifier A4, a difference (i-ii), i.e., a track error signal is obtained. This track error signal drives a track actuator TA and is always set at zero. While the added output (i+ii) is obtained from an addition amplifier A5 and divided into 1/2 as long as the spot of a light beam S3 is set at the center of a track T. Then a defect of an optical disk D is decided if the output (i+ii) is reduced less than the reference voltage REF. Then a comparator A8 delivers an output to control an automatic gain control circuit AGC.

Title: Rudder structure of ship
Inventor: YAMAGUCHI SEIKI
IPC: B63H25/38
Filed: 1986-01-28
Abstract: PURPOSE:To improve steerability during crawling forward propulsion and backward propulsion by supporting a propeller shaft exposed outside a ship with a shaft bracket and forming a rudder having a streamlined cross section behind it together with the bracket. CONSTITUTION:A connecting bar 8 is connected to the tip of an arm 41, and arm lengths from a rudder shafts 40 and 60 to the connecting bar 8 are made equal, then a steering force is transmitted from the arm 41 to the rudder shaft 40 by a hydraulic steering gear 7 to rotate a rudder 4, and a rotating force is transmitted to a rudder shaft 60 via an arm 61 from the connecting bar 8 to rotate a rudder 6 to the same angle as the rudder 4. Accordingly, during forward propulsion, the accelerated stream from a propeller 2 hits the rudder 4 to generate a turning force, also the inflow stream of the propeller 2 is deflected by the rudder 6 to generate a turning force, thus steerability is improved even during crawling forward propulsion. During backward propulsion, the inflow stream of the propeller 2 is deflected by the rudder 4, and the accelerated stream from the propeller 2 hits the rudder 6, thus steerability is improved. Since the rudder 6 is arranged behind a shaft bracket 5, the stream is rectified and a vortex is prevented, and propulsion resistance is decreased.
