Title: Compressed air source equipment
Inventor: MURASE YOSHIAKI
IPC: B01D53/26
Filed: 1987-01-26
Abstract: PURPOSE:To easily recognize the exchange period of an adsorbent by providing both an integrating device for integrating actuations of a regenerator and an alarm, generating a signal when the integration reaches prescribed value in a compressed air source equipment equipped with an air drier. CONSTITUTION:During a loading cycle, compressed dry air is fed to an air storage tank 6 via an air drier 3, a purge storage tank 4 and a check valve 8 and the output of a pressure switch is a level (0). When an unloading command is generated, feed of compressed air to a compressed air drier 3 is stopped and an injection-valve for a regenerator 5 is opened and thereby compressed dry air incorporated in the purge storage tank 4 flows bank into the air drier 3 and flows out to the atmosphere after regenerating an adsorbent. Therefore, the pressure of the inside of a duct part 7a is lowered to preset value or below and the pressure switch 10 is actuated and discrete value of a counter 11 is increased by (1). In such a way, every time a purge cycle is started by the unloading command, the discrete value of the counter 11 is increased and reaches the preset value. At this time, a signal is fed to an alarm 12 from the counter 11 and the alarm 12 is lighted and informs that the capacity of the adsorbent is lowered to the limited level.

Abstract: PURPOSE:To reduce cost of tape by separably laminating a carrier tape and its protection tape and transferring them. CONSTITUTION:A film carrier tape is composed, for example, of a carrier tape 1 where a plating layer 3 such as tin is formed on a copper foil 2. This carrier tape 1 has an inner lead 6 for fixing and connecting a bump 5 made of gold, etc. of a pellet 4. A protection tape 7 has the width and pitch of feed holes which are substantially the same as the width and the pitch of feed holes 8 of the carrier tape 1. This protection tape 7 and carrier tape 1 are respectively laminated so that the feed holes 18 are matched but these are not fixed each other and can be separated easily. Therefore, since the carrier tape 1 is made of only a metal foil, a cost of tape is very low and the carrier tape 1 is transferred together with the protection tape 7. Accordingly, the carrier tape 1 is not deformed and broken and the protection tape 7 can be used many times repeatedly.

Title: Lighting device for discharge lamp
Inventor: NAGAI SATOSHI
IPC: H05B41/42
Filed: 1991-02-06
Abstract: PURPOSE:To prevent discharge from being stopped halfway by gradually increasing the output frequency of an inverter used for lighting a discharge lamp in such a manner that a predetermined time is taken for the output frequency to be increased, so as to dim the light of the discharge lamp. CONSTITUTION:When a lighting switch 2 is on, a starting high voltage is applied to a discharge lamp 5 and then the output of an inverter 6 keeps the discharge lamp 5 lighting. When a dimming switch 10 is on under those conditions, a frequency setting circuit 11 gradually increases the output frequency of an inverter 6 to a fixed frequency via an inverter driving circuit 7: Then the discharge lamp 5 is gradually shifted to its dimming state while a predetermined time is taken for the lamp to be shifted to that state : trouble that may arise when the lamp is shifted to that state within a short time is thus avoided while preventing discharge from being stopped halfway and hence the discharge lamp 5 from being turned off.
