Title: Improved method of epoxidation catalyzed by titanium silicalite
Inventor: GAI ERU KUROTSUKO
IPC: C07B61/00
Filed: 1995-11-10
Abstract: The selectivity of an olefin epoxidation process catalyzed by titanium silicalite is improved by performing the epoxidation in the presence of minor amounts of nonbasic salts such as lithium chloride, sodium nitrate, potassium sulfate, and ammonium dihydrogen phosphate. For example, when hydrogen peroxide is reacted with propylene to form propylene oxide, non-selective ring-opening reactions of the propylene oxide are suppressed when low concentrations of a nonbasic salt are added to the hydrogen peroxide feed.

IPC: G02B6/12
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain a waveguide chip at prescribed temperature without increasing electric power consumption even if outdoor temperature rises high by covering the endothermic side periphery of at least a temperature compensating means in a package with thermally insulating material.

Filed: 1988-12-15
Abstract: PURPOSE:To obtain a small conversion loss and a wide band frequency characteristic by providing two short-circuits, two RF signal interruption circuits and output terminals connecting to the two RF signal interruption circuits to a conventional mixer. CONSTITUTION:An RF signal inputted from a terminal 1 is fed to a diode 6 through a strip/slot converter 1, a local oscillation signal interruption circuit 2, a strip/slot converter 3, a slot/strip converter 4 and short-circuited completely by a short-circuit 9 connecting to the rear side of the board. Moreover, the local oscillation signal inputted from a terminal 2 is fed to the diode 6 through the converters 3, 4 and short-circuited by the short-circuit 9. In this case, the RF signal and the local oscillation signal are not led to a terminal 3 because of the presence of an RF signal interruption circuit 8. Furthermore, an intermediate frequency signal generated from the two diodes 6 passes through the RF signal interruption circuit 8 and is outputted from the terminal 3 after being synthesized. Thus, the conversion loss is small and wide band frequency characteristic is obtained.

Title: Precise stage
Inventor: NAGANO HIROYUKI
IPC: G05D3/12
Filed: 1990-11-20
Abstract: PURPOSE:To extremely shorten the total positioning time by providing the rough and fine adjustment position detectors which are independent of each other, securing the simultaneous operations of both detectors, and attaining the correction of an error through the fine adjustment positioning device in a fine adjustment positioning state. CONSTITUTION:A control curve generator 8 sends the information to a position command value distributor 9 with input of the shift command value. The distributor 9 distributes the received information after decomposing it into the unit of a rotary encoder 4 and the unit of laser length measuring instrument. A rough adjustment deviation counter 10 subtracts the pulse value in accordance with the revolution of a motor 2. Then the deviation value is balanced and the positioning operation is finally over at a rough adjustment stage 1 with an allowance residual error of the rough adjustment stage. A fine adjustment deviation counter 12 subtracts the pulse value corresponding to the shifted variable of the stage 1, and a piezo-element 6 moves according to the error of the stage 1. The residual error of the rough adjustment stage is substantially corrected when the rough adjustment stage is positioned because the error of the fine adjustment stage is corrected right after the start of the rough adjustment stage. Thus the total positioning time is shortened.
