Title: Compressor for gas turbine
Inventor: HAMACHI YASUYUKI
IPC: F04D29/44
Filed: 1991-01-30
Abstract: PURPOSE:To reduce the air energy loss by connecting a fore stage compression part and an aft stage compression part through an air collector having a wide sectional area and a large capacity and installing a rectifying guide on the suction side in the aft stage. CONSTITUTION:A gas turbine is equipped with a centrifugal type fore stage compression part 11 and a centrifugal type aft stage compression part 12, and an air collector chamber 50 is formed between both. Gas is compressed by the revolution of the fore stage compression part 11 and introduced into the air collector chamber 50 from a discharge part 11a. In this case, low speed is generated, and the kinetic energy is converted to the pressure energy, and the energy loss due to the conduit resistance is reduced extremely. The gas is guided into the suction part 12a of the rear stage compression part 12 by a rectifying guide 51. Accordingly, the loss of the air energy can be reduced markedly.

Title: Air conditioner
Inventor: HOJO TOSHIYUKI
IPC: F25B29/00
Filed: 1990-03-09
Abstract: PURPOSE:To reduce the sound of a flowing refrigerant at the time of opening of a switching valve for selection of cooling and heating by detecting a pressure difference before and behind a compressor, by comparing the detected pressure difference with a reference pressure difference set beforehand and by staggering the switching time of the switching valve and a pressure reducing device for an indoor heat exchanger. CONSTITUTION:When an operation is switched over to a heating operation in an indoor unit 2a, first a pressure difference obtained from measured values of pressure sensors 5 on the high pressure side and the low pressure side is compared with a pressure difference whereat generation of the sound of a flowing refrigerant is estimated and which is used as a set value. When the result of comparison shows that the pressure difference is larger than the set value, a solenoid value 21 for selection of cooling is closed. Herein, the pressure Px in a heat exchanger 3a of the indoor unit is Ps. When a pressure reducing device 4a for the indoor unit is opened in succession, however, the pressure Px turns equal to PL due to inflow of a liquid refrigerant. When a solenoid valve 11 for selection of heating is opened, moreover, a gas refrigerant flows in under a pressure Pd, and the pressure Px inside the heat exchanger 3a of the indoor unit becomes equal to Pd.

Title: Drilling tool
Inventor: NAKAMURA SHINICHI
IPC: B23B51/00
Filed: 1986-03-14
Abstract: PURPOSE:To select a circumferential setting angle of a tool and situate a chip discharging groove to an angle favorable in dischargeability, by installing plural pieces of a bearing surface on the circumference of a shank part of a drilling tool in the circumferential direction. CONSTITUTION:A drill is attached to a lathe in a way of fitting its chank part 14 in the drill inserting hole. At this time, the drill is inserted so as to cause two straight grooves 13b to be situated sideways to a drill axial center so as to make chips easily dischargeable, and it is clamped with a clamping bolt 25 pressed to a bearing surface 31. Since this bearing surface 31 is installed several pieces on the circumference of a shank part 14, the straight groove 13b can be situated sideways at the drill axial center irrespective of a setting angle of the clamping bolt 25. Therefore, for any kind of a device, drill attachment is made performable in a state favorable in chip dischargeability.

Title: Portable printer
Inventor: SEKI YASUHIRO
IPC: H05K5/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To furnish cushion members to absorb the dropping impact and to be an nonslip material as used at a table. SOLUTION: The exterior case 2 of a portable printer 1 used in carrying or on a table is provided with cushion members 7 having configurations to cover corners to absorb impact and form a nonslip material. Inasmuch as cushion members 7 have an elasticity of rubber or the like and formed of a material with a relatively high coefficient of friction relative to the surface of a table, the portable printer 1 can be made hard to slip on the table by attaching the cushion members 7. Also, if the cushion members 7 are secured, even in the case where one has dropped erroneously from the table or on carrying it, the cushion members 7 absorb the dropping impact resulting in avoiding that the exterior case 2 is broken.

Title: Bipolar mos logic circuit
Inventor: YASUDA TAKATOSHI
IPC: H03K19/08
Filed: 1989-03-09
Abstract: PURPOSE:To prevent the flowing of a through-current by interrupting a transistor(TR) connecting to a high level before two TRs of series connection connecting to an output section are conductive simultaneously. CONSTITUTION:When a high level signal is inputted to an input terminal 4, an N-channel MOS TR 11 is conductive to make a P-channel MOS TR 15 conductive, a base driving current is injected to the base of an NPN TR 17 with an SBD, thereby making the level of an output terminal 3 to a low level. On the other hand, when a low level signal is inputted to the terminal 4, the P-channel MOS TR 12 is conductive. Then a P-channel MOS TR 10 is conductive and the TR 15 is made nonconductive, then the level of the base of the NPN TR 13 with SBD in Darlington connection with the NPN TR 14 rises to make the level of a terminal 3 high. Then the base storage charge of the TR 17 is extracted by the conduction of the N-channel MOS TR 16. Thus, the path of the through. current is suppressed to decrease the through-current.
