Title: Production of carbonic acid diester
Inventor: NISHIHIRA KEIGO
IPC: C07C69/96
Filed: 1993-02-03
Abstract: PURPOSE:To stably produce a carbonic acid diester for a long period in high selectivity and yield by carrying out the vapor-phase catalytic reaction of an alkyl nitrite with carbon monoxide at a specific molar ratio in the presence of a specific solid catalyst having low acidity. CONSTITUTION:A carbonic diester is produced by carrying out the vapor-phase catalytic reaction of an alkyl nitrite with carbon monoxide at an (alkyl nitrite)/ CO molar ratio of >=2 (especially 3-10) at 0-200 deg.C (especially 50-150 deg.C) in the presence of a solid catalyst having low acidity and produced by supporting 0.1-10wt.% (especially 0.5-5wt.%) (in terms of platinum group metal) of a platinum group metal ion (especially Pd ion) to an ion-exchanging zeolite carrier by ion-exchange. The vapor-phase catalytic reaction is preferably carried out in the presence of 0.1-3mol% of water (based on the total amount of the raw material gas supplied to the reaction system) to keep the activity of the solid catalyst at a high level for a long period. The ion-exchanging sites of the catalyst other than the sites occupied by the supported platinum-group metal ions are preferably neutralized or ion-exchanged with an alkali metal or alkaline earth metal ion.

Title: Discharge lamp lighting device and lighting fixture
Inventor: SHIOHAMA HIROCHIKA
IPC: H05B41/18
Filed: 1995-02-02
Abstract: PURPOSE: To prevent the service life of a discharge lamp lighting device from being shortened, due to the insulation drop thereof, by eliminating the occurrence of lamp flashing as a result of the rise of lamp voltage at the end of the service life. CONSTITUTION: When a discharge lamp reaches the end of a service life and lamp voltage VL rises relatively quickly to the preset value, a timer circuit 3 operates on DC voltage V2 on the basis of the lamp voltage VL. In a lighting condition at the end of the service life, however, the timer circuit 3 operates only over the second preset time (e.g. 20 seconds) and, then, the operation time is up. Thereafter, even when the lamp is turned off and no load condition appears, the operation time of the circuit 3 is already up and, therefore, the lamp is kept in an off-state. In a no-load condition, a pulse generation circuit 4 operates and the lamp is again turned on, thereby ensuring freedom from a concern about the repetition of flashing due to re-extinguishment.  According to this construction, a discharge lighting device can be protected against deterioration due to the effect of high pressure pulses at the end of the service life.

Title: Non-hit switching system
Inventor: HODOHARA KIYOAKI
IPC: H04B1/74
Filed: 1985-01-31
Abstract: PURPOSE:To reduce the number of input/output signal lines connected between a working system and a spare system down to two pieces and at the same time to omit the necessity to provide previously a switching function, etc., by using (n) pieces of switch devices which select (n) pieces of outputs of a distribution part and the output of a working reception device together with a spare transmission device and a spare reception device and performing the switch in case the working system has a trouble. CONSTITUTION:A branch circuit 1-1 is not connected to a transmission end parallel switch 6-1 as long as a working system 1 has normal actuation. Then the input signals are sent in parallel to a spare system via the switch 6-1 when the system 1 has a trouble. At the reception terminal side, the signals supplied from a spare reception device are distributed by a distributing part, e.g., a distributing circuit 7-1 consisting of a buffer amplifier and then delivered to outside via a non-hit switching circuit 4-1. The number of output signal lines connected between the system 1 and the spare system can be cut down to two pieces by decentralizing the switch functions and distribution functions so far concentrated to the spare system to each working system. This facilitates the easy wiring and packaging of the spare system.

Title: Electromechanical timepiece
Inventor: RUNE BESON
IPC: G04C3/14
Filed: 1978-02-16
Abstract: An electro-mechanical watch for advancing the uncorrected watch indicating members to their correct time indicating positions, after a correction period during which one of the indicating members is adjusted and the advancement of the uncorrected members is interrupted. In regular operation, a pulsed signal at a normal frequency from a watch frequency divider drives a stepping motor to advance the indicating members. At the beginning of the correction period, the pulsed signal is switched from the stepping motor to a pulse counter which counts the pulses occurring during the correction period. After the correction period, the pulsed signal is switched back to the stepping motor and a number of signal pulses at a higher than normal frequency, equal to the count of the pulse counter are applied to the stepping motor to advance rapidly the uncorrected indicating members to their correct time indicating positions.

Abstract: PURPOSE:To perform accurately a desired operation by providing an aural guide function into an exchange device. CONSTITUTION:The sentences, paragraphs and words which are needed for aural guide are stored in the sound information file 5 in the form of sound parameters. A central controller 6 reads the sound parameters of desired sentences, paragraphs and words out of the file 5 according to an operation request and the information on confirmation of operations to a user. Then the controller 6 edits the guide sentences to the user and transfers them to an aural guide trunk 7. The voices are synthesized from the sound parameters at the trunk 7 and given to the user. Thus it is possible for a user to use a communication system more effectively and more conveniently even though he/she does not know how to operate the system previously.

Filed: 1995-02-06
Abstract: PURPOSE: To form a super fine pattern by exposing photoresist by superimposition by using first and second photo masks that differ only by the positions of a chromium pattern and a phase inverted material pattern and by exposing other regions by superimposition by using third and fourth photo masks that differ only by position. CONSTITUTION: A first photo mask 11 is manufactured by forming many chromium patterns 12 and phase inverted material patterns 13 on a quartz substrate 14. Second, third and fourth photo masks 21, 31 and 41 are formed by same constitution as that of the first photo mask 11. The photomasks 11, 21, 31 and 41, however, are formed to have their chromium patterns and the phase inverted material patterns positionally deviated by design rule when the photo masks are alternately superimposed. A photoresist pattern is formed by performing primary exposure by using the first photo mask 11, mounting the second photo mask 21 at the position where the first photo mask 11 is removed, and performing secondary exposure by superimposition. Then, superimposed exposure is performed by using the third and the fourth photo masks 31 and 41.
