Title: Production of optically active carboxylic acids
Inventor: ISOBE TOSHIO
IPC: C07C51/06
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To selectively produce optically active carboxylic acids of high optical purity useful in industrial fields such as medicines, agrochemicals, perfumes, food additives and electronics in high yield. SOLUTION: An optically active 4,5-diphenyl-2-imidazolidinone derivative represented by formula II (R<1> is an alkyl, etc.; R<2> is a dialkoxyphosphoryl or a halogen; * indicates the position of asymmetric carbon) is reacted with an aldehyde represented by the formula R<3> CHO (R<3> is an organic group) to afford an α,β-unsaturated acyl compound represented by formula III. The Michael addition reaction or Michael type addition reaction of the resultant α,β-unsaturated acyl compound represented by formula III is then carried out by using a reagent having an organic group R<4> different from R<3> to provide a diastereomer represented by formula IV (R<4> is the organic group different from R<3> ), which is then hydrolyzed to afford optically active carboxylic acids represented by formula I, e.g. (4S,5S)-1-cinnamoyl-4,5-diphenyl-3-methyl-2-imidazolidinone.

Title: Tuner circuit
Inventor: MIZUKAMI HIROYUKI
IPC: H04B1/18
Filed: 1992-02-03
Abstract: PURPOSE:To obtain the wide band reception tuner circuit which can receive BS (satellite broadcast) signals and TV signals with simple circuit configuration by providing an IF filter and an input filter to enable the control of passing band characteristics. CONSTITUTION:An IF filter 109 is composed of a special circuit or a switched capacitor circuit based on an integration circuit. An input filter 107 is composed of N pieces of bus filters using this IF filter 109 as a pass filter. The BS signals are inputted from a terminal 1, and the TV signals are inputted from a terminal 2.

Title: Optical type displacement detection apparatus
Inventor: HANAOKA HIROSHI
IPC: G01D5/30
Filed: 1984-02-02
Abstract: PURPOSE:To exclude the influence of optical properties due to the surface state and material quality of the attachment place of a main scale, by providing a glass plate provided with a disturbance preventing layer to the main scale in the side opposite to an index scale and attaching said main scale to a main body through said glass plate. CONSTITUTION:Because a disturbance preventing layer 12 is arranged to the rear surface side (the side opposite to an index scale 2) of a main scale 1, light transmitting the non-reflective parts 5B of the checkered pattern 5 of the main scale 1 is not reflected to the side of the index scale 2 or reflected to the side of said index scale 2 as constant reflected light and, by this mechanism, the accurate detection of displacement can be performed without generating noise in a light receiving element 8. That is, a measured value is not affected by optical properties in the side of a main body 3 and, because the main scale 1 may be merely attached to the main body 3 through the glass plate 11 provided with the disturbance preventing layer 12, attachment is also easy.

Filed: 1988-01-27
Abstract: PURPOSE:To improve the durability of a mechanical constituting part which is concerned with a collision with an infinity position of a lens by a decelerating a driving speed of the lens before the lens reaches a terminal position at the time of executing low contrast scan. CONSTITUTION:At the time of a regularly detecting focus, a lens 1 is driven toward a focusing position, based on a result of detection of a focus detecting means 2. When the present position NL of the lens 1 is not within a prescribed distance NA from an end point position Nmax being in the driving direction of the lens 1, a speed control means 11 drives the lens 1 at a first speed V1. When a position NL is within the prescribed distance NA from a position NMAX, and also, the driving direction of the lens 1 is the direction going to the position NMAX, a speed for driving the lens is controlled by a scan control means 5 so that the lens 1 is driven at a second speed V2 being lower than the speed V1. In such a way, the durability of a mechanical constituting part which is concerned in a collision with an infinity position of the lens can be improved.

Title: Tempering of glass
Inventor: YUGAWA HIROYUKI
IPC: C03B27/02
Filed: 1984-02-02
Abstract: PURPOSE:To carry out the tempering treatment of a thin glass plate without causing the breakage of the glass during cooling, by heating a glass plate at a high temperature, and dipping and quenching in a viscous oil heated at a low temperature. CONSTITUTION:A thin glass plate is heated at a high temperature (about 600- 700 deg.C) near the critical temperature to cause the deformation of the glass, and is quenched rapidly by dipping in an incombustible viscous oil (e.g. engine oil) heated at a relatively low temperature higher than normal temperature (i.e. about 65 deg.C). The method is suitable especially to a thin glass plate having a thickness of about 1mm.. The abrupt temperature decrease in cooling can be mitigated, and the breakage of the glass plate by the strain can be prevented by this process. Even a thin glass plate tempered by this process forms granular pieces when broken under impact.

Title: Synchronization controller of synchronous motor
Inventor: MATSUDAIRA TAKAYUKI
IPC: H02P1/52
Filed: 1979-02-19
Abstract: PURPOSE: To rapidly reach the speed of a synchronous motor to its synchronous speed even at its nearly synchronous speed by controlling the motor by applying the sum of a synchronization auxiliary signal regardless of frequency difference and a synchronization signal to a standard signal generator circuit.  
     CONSTITUTION: A synchronous speed standard circuit 7 for controlling a variable speed drive unit 5 for driving a synchronous motor 1 employs the sum of a value integrated with the sum of a signal from a synchronization signal circuit 9 and a signal from a synchronization auxiliary signal circuit 14 and of a value added with the speed standard in the standard circuit 7 as a standard signal. The synchronization circuit 9 produces an acceleration or deceleration signal according to the difference in frequency between an AC bus line 2 and the motor 1. The auxiliary circuit 14 produces an acceleration or deceleration signal regardless of the frequency difference. Accordingly, the motor can be controlled to its synchronous speed rapidly even in the vicinity of the synchronous speed with the circuit 14 added. In addition, even after the motor reaches its synchronous speed, the motor 1 is again accelerated or decelerated when the phase difference is not coincident to thereby equalize the phase difference.
