Title: Microwave generating unit and plasma processing apparatus comprising the same
Inventor: TOYODA NAOKI
IPC: H01L21/302
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive and small size microwave generating unit. SOLUTION: A semiconductor switching element 13 supplies a pulse of the operating voltage to a magnetron 11 connected to the output side by repeating the conductive/non-conductive conditions. When the semiconductor switching element 13 is in the non-conductive condition, a capacitor 15 which has been charged during the conductive condition thereof is in turn discharged. Consequently, an output side voltage of the semiconductor switching element 13 is maintained at the predetermined voltage. The output side voltage maintained in this case is lower than the minimum operating voltage of the magnetron 11 and an input/output voltage difference of the semiconductor switching element 13 is lower than the dielectric voltage.  Therefore, a small size microwave unit for generating the microwave pulse can be manufactured at a low cost by utilizing a low price and small size semiconductor switching element.

Abstract: PURPOSE:To reduce the generation of passage noise of the refrigerant flow of an indoor heat exchanger by a method wherein an outdoor heat exchanger and an expansion means, and an indoor heat exchanger and a 4-way valve are intercoupled through a bypass pipe and a solenoid valve is located in the bypass pipe, and during defrosting, the solenoid valve is opened at a given opening. CONSTITUTION:During execution of heating operation, when frost is formed on an outdoor heat exchanger 23, a 4-way valve 22 is switched and a refrigerant is circulated reversely, and a fan motor 29 of an indoor heat exchanger 27 is stopped to perform defrost. Simultaneously, a solenoid valve 32 located in a bypass pipe 31 through which the outdoor heat exchanger 23 and an expansion means 26, and the indoor heat exchanger 27 and the 4-way valve 22 are intercoupled is opened at a given opening, and the bypass pipe 31 is brought into a communication state. A part of a refrigerant by means of which frost adhered to the outdoor heat exchanger 23 is molten is returned through the bypass pipe 31 to a compressor 21. This constitution reduces an amount of a refrigerant flowing through the indoor heat exchanger 27, reduces the generation of passage noise of the refrigerant flow of the indoor heat exchanger 27, and prevents a user from hearing the passage noise even when a fan motor 29 is stopped.

Title: Sheet feeding device and image forming device equipped with the sheet feeding device
Inventor: NAKAGAWA TOMOHITO
IPC: B65H3/06
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent a feeding failure of document, rising of a system cost, lowering of the feeding speed of the document and the like. SOLUTION: In pick-up DOWN processing, when an elevator arm 51 goes down, the engagement of an arm shaft 51c and a swing arm 53 is released and a paper feeding roller 5 contacts with documents P by its self-weight. When the roller 5 is rotated under this condition, the roller 5 can feed the documents P always in a stable condition regardless of the stacked height of documents. In this case, as stable feeding can be secured by a simple mechanism, a cost can be reduced. In the case of continuous feeding, the roller 5 is controlled to stop halfway at a position separated about 3-5mm from the top document (a taking refuge position shown in (b)), each time documents are fed. Accordingly, in pick-up DOWN processing for next documents, the moving quantity of the roller 5 can be reduced and vibration to be caused when the roller 5 contacts with the document can be reduced.  As a result, the time in which the rotation of the roller 5 is suspended can be shortened and the feeding speed of documents can be increased.

Title: Optical head and adjusting method therefor
Inventor: YOSHIZAWA TAKASHI
IPC: G11B7/08
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To reduce a beam shift by configuring an optical head with multiple objective lenses so that an elastic member restricts position of a supporting part of the objective lenses as the reference to the one with the highest numerical aperture. SOLUTION: When the center of an objective lens can be regarded as practically not shifted, a tip of an elastic member 41 is made to be engaged in a V-groove 17 of a lens holder 15 in a state that an objective lens 11a of higher numerical aperture is selected, and its root is also made to coincide with a design center position 42 of a yoke 14 to be bonded with an adhesive 43. Further, since the elastic member 41 has a viscoelastic characteristic and the objective lens 11a of higher numerical aperture is selected, no influence is exerted on a driving characteristic of the objective lens 11a even when the elastic member 41 is engaged with the V-groove of the lens holder 15. Conversely, the viscoelastic characteristic of the elastic member 41 brings a reduction in a resonance peak value of the whole actuator.
