Title: Production of optically active 4-hydroxy-2-cyclopentenone
Inventor: UEDA YUJI
IPC: C12P7/38
Filed: 1986-06-18
Abstract: PURPOSE:To obtain the titled compound having high optical purity in a short time and in high yield, by hydrolyzing optically active 4-acetoxy-2- cyclopentenone with an enzyme having bacterium derived esterase activity. CONSTITUTION:Sulfonic acid ester of optically active 4-hydroxy-2-cyclopentenone is treated with sodium acetate to give optically active 4-acetoxy-2-cyclopentenone having steric coordination opposite to original one. A blend of the compound and an enzyme having esterase activity derived from a bacterium belonging to the genus Arthrobacter, Candida, Chromobacterium or Pseudomonas or a combination of the enzyme and the bacterium is vigorously stirred in a buffer solution preferably at pH 5-8, 0.05-0.5 M concentration at 10-60 deg.C reaction temperature usually for 0.5-7hr and the aimed optically active compound is obtained from the reaction solution. EFFECT:Steric inversion of optically active 4-hydroxy-cyclopentenone can be readily carried out.

Title: Ac power source device
Inventor: TSURUOKA TOSHIAKI
IPC: H02M7/538
Filed: 1988-06-09
Abstract: PURPOSE:To improve efficiency and to make a device small-sized and inexpensive by providing an LC filter by the use of the transformer leakage inductance and the capacity of the secondary winding and by regulating the slope of leading and trailing edges of the modulated trapezoidal pulse wave. CONSTITUTION:An AC power device connects a DC power source 14 between power terminals 12 and 13. The power terminal 12 is connected to the intermediate tap of the primary winding of a transformer 1. It is connected from the primary winding of the transformer to the other power terminal 13 through a pair of transistors(Tr) 2 and 3, while it connects regenerative diodes 7 and 8 to the Trs 2 and 3. High frequency pulses modulated so that the time ratio varies trapezoidal-wave-wise with respect to time are given from a pulse width control oscillator 4 to the bases of the Tr 2 and 3, which are operated to turn ON alternately. To both ends of the secondary winding of the transformer 1 a capacitor 15 is added. A resonance circuit is thereby dispensed with, so that the loss by DC resistance component and dielectric loss will extremely be reduced.

Title: Gate circuit of gto
Inventor: NAKAGAWA AKIO
IPC: H03K17/73
Filed: 1978-11-20
Abstract: PURPOSE:To ensure a high-gain operation by inserting the inductive load between the GTO and the gate circuit. CONSTITUTION:The load of inductance L15 is inserted between gate circuit 12 and gate 10a of GTO10. Circuit 12 consists of ON-pulse gate circuit 12a and OFF-pulse gate circuit 12b. Thus a large amount of the turn-off enable current value can be kept by securing a high level of voltage between gate G and cathode K when the GTO is turned off. Accordingly, the current value can be kept at a high level via inductance L15, obtaining a high gain.

Patent JP-H037419-A (JP)
Title: Frequency discrimination circuit
Inventor: MATSUMOTO HIROAKI
IPC: H03K5/19
Filed: 1989-06-05
Abstract: PURPOSE:To discriminate the frequency of an input signal by delaying the input signal inputted to a data terminal of a D flip-flop circuit by a prescribed time with a delay circuit, and supplying the delayed signal to a clock terminal of the D flip-flop circuit. CONSTITUTION:A signal of 8MHz (figure A) or 10MHz (figure B) is inputted to a data terminal D of a D flip-flop circuit 11. The period of the frequency of 8 and 10MHz is respectively 125ns and 100ns. The delay time of a delay circuit 12 is selected to be, e.g. 112.5ns (=125+100/2), which is longer than 100ns and shorter than 125ns. Thus, the signal of the period 125n and 100ns shown in figures A, B is delayed by 112.5ns by the delay circuit 12 and comes to a signal of a phase shown figures C, D, respectively. Since a logical L is outputted when a 8MHz signal is inputted to the data terminal D, and a logical H is outputted when a 10MHz signal is inputted to the data terminal D from a terminal Q of the D flip-flop circuit 11, the frequency is discriminated depending on the output.

Title: Socket for integrated circuit package
Inventor: TANIGAWA YUKIHIKO
IPC: H01R33/76
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To stably and excellently maintain the electrical contact with a package without generating a damage in a bump by using a projecting contact part, which is formed of a conductive and elastic member, for contact of a socket with the bump. SOLUTION: A socket 4 has a contact pin 6. The contact pin 6 is formed of a contact 13 and a lead 12, and the contact 13 is made of the conductive rubber. The contact 13 elastically contacts with both of the bump 3 and the lead 12 for electrical connection. The contact part 9 is formed into a projecting shape. The socket 4 has fixed levers 15 for fixing a package 1. When the vertical force is applied downward to the package 1 by the fixed levers 15, the bump 3 bites a contact part 9 of the contact 13 made of the conductive rubber. Since the contact 13 made of rubber has elasticity, it generates the upward repulsive force in the vertical direction in relation into the lead 12. The package 1 is fixed at a position, in which two of the elastic force and the repulsive force are balanced between the bump 3 and the contact part 9 of the contact 13.
