Title: Treatment of gas containing organic vapor
Inventor: INOUE KENICHI
IPC: B01D53/22
Filed: 1989-09-25
Abstract: PURPOSE:To make it possible to cope with a change of the concn. of org. vapor by returning part of permeated gas to the gas feeding side of a module in accordance with the detected concn. of the org. vapor in unpermeated gas. CONSTITUTION:When the concn. of org. vapor in gas fed from a gas feeding source S to a module 1 rises, the concn. of the org. vapor in unpermeated gas lowers. At the time when the concn. of the org. vapor in the unpermeated gas attains to the upper limit, a detector 8 detects the concn. and a control valve 5 fitted to a return pipe 4 is opened in accordance with the detected signal. Part of permeated gas is added to gas fed from the gas source S, mixed gas having a high concn. of org. vapor is sent to the module 1 and the concn. of the org. vapor in unpermeated gas lowers. It becomes unnecessary to increase the capacity of the module in excess and the consumption of electricity can be reduced.

Title: Rough seek controller for optical head
Inventor: TAKAHASHI SATORU
IPC: G11B21/10
Filed: 1988-10-04
Abstract: PURPOSE:To reduce a shift in the mid-point of the optical head while the optical head is in tracking operation or in operation under relative speed control by providing a wid-point shift detecting means which detects the quantity of the movable range of the optical head. CONSTITUTION:A switching circuit 5 is switched to a mid-point control circuit A4 at the same time with the start of rough seeking operation, so the optical head 11 is controlled and held at the mid-point of its movable range at all times by a mid-point control circuit A4 which inputs a mid-point dislocation signal 15a from a mid-point dislocation sensor 15. Therefore, while a head feeding mechanism 12 is in speed control operation after the start of rough seeking operation by using a linear scale signal 14a from an external scale sensor 14 as a feedback signal, the optical head 11 operates for mid-point control A based upon the mid-point dislocation signal 15a from the sensor 15. Consequently, the dislocation of the optical head 11 from a movable mid-point due to the acceleration or deceleration of the head feeding mechanism 12 in the rough seeking operation can be reduced.

Patent JP-H0297810-A (JP)
Title: Burner
Inventor: FUJITA TATSUO
IPC: F23D11/40
Filed: 1988-10-04
Abstract: PURPOSE:To reduce flying flames in a burner, when the combustion is at a high rate, and achieve excellent characteristics of partially premixed fuel, when the combustion is at a low rate, by forming flame holes at downstream outlets of fuel-air mixture- supplying passageways by which a combustion chamber communicates with fuel-air mixture branch pipes and by forming a plurality of flame holes in multiple ranges toward the outlet of the combustion chamber. CONSTITUTION:A sheathed heater 30 is turned on, and when a vaporizing cylinder 29 has been heated up, fuel 39 is ejected from a fuel nozzle 32. The fuel 39 vaporizes as it impinges against a vaporizing cylinder 29 and is mixed with primary air 40, which has been sent simultaneously, to form a fuel-air mixture 41 and flows into a mixing chamber 27. The fuel-air mixture thereafter flows into fuel-air mixture branch pipes 23 and through a plurality of fuel-air mixture-supplying passageways 24 and is fed into a combustion chamber 21 through flame holes 22, which are opposed coaxially to other flame holes, ignited, and forms opposed flames 42. The opposed flames 42 lose speed where they collide into each other in the combustion chamber 21 so that the resulting slack in flow serves to stabilize the flames. As a result, flying flames are reduced even when the combustion is at a high rate or the primary air assumes a larger ratio.
