Title: Pumping equipment
Inventor: KOBORI MUNEO
IPC: F04D29/58
Filed: 1987-12-25
Abstract: PURPOSE:To eliminate the need of fitting working for a fan and to facilitate assembling by inserting a shaft of an electric motor in a pump through a space formed between the electric motor and the pump, fixing an impeller to the shaft, and clamping a fan in the space. CONSTITUTION:A shaft 5 of an electric motor 1 is passed through a fan 7 to assemble a pump 2, and an impeller 8 is screw-enganed with the shaft 5, whereby the fan 7 can be easily and firmly fixed to the shaft. Further, the fan 7 is fixed to the impeller 8 in the rotating direction, with a projecting portion 10 connected to a recess portion 11, so that even if load is imposed on the fan 7, the fan can be rotated with the shaft 5 and cooling air flows through vent holes 9a, 9b cool the electric motor 1. In this arrangement, fitting for the fan 7 is clamped by the impeller 8, so that it is not necessary to work the shaft 5 for fitting the fan 7 and even if the shaft 5 is made longer, the mechanical strength will not be lacking and assembling can be facilitated.

Title: Planar type laser diode
Inventor: TAKAHASHI SHOGO
IPC: H01S5/00
Filed: 1990-11-27
Abstract: PURPOSE:To manufacture a planar type laser diode without P-type diffusing driving step by inclining an active region, and bringing a P-type diffusion front into coincidence with the vicinity of the interior or the end of the inclined part. CONSTITUTION:An active region is inclined, and a P-type diffused region 6 is selectively formed to the periphery of one end of the inclined region 81. A current injected from a P-type electrode 9 flows to the region 81 to emit a light. In this case, one end of the region is formed with a waveguide by a difference of refractive indexes due to bending of the active layer (in this case, a difference of the refractive indexes of materials of InGaAs and AlGaInAs), and the other end is formed with a waveguide by a difference of refractive indexes due to impurity concentrations of a P-type diffused region 6 and an n-type InGaAs layer 5, and an output light is confined thereon to be oscillated. Thus, a planar type laser diode of a structure in which a drive diffusion due to a high temperature is not required, is obtained.

Title: Magnetic disk device
Inventor: SOGABE CHIKAYUKI
IPC: G11B25/04
Filed: 1987-12-25
Abstract: PURPOSE:To prevent misalignment of a head due to residual torque in tightening a screw by putting a washer having a spring property between a head bar and a head clamp and pressing the head clamp so as to hold down the head bar to be fixed with. CONSTITUTION:In a carriage assembly part with a carriage 4 fitted alternately with the head bar and a head spacer 9, a magnetic head 6 is fixed to the carriage 4 by fixedly holding the magnetic head 6 between the carriage 4 and the head clamp 7. That is, the washer 12 having a spring property is placed between the head bar and the head clamp 7, and when the head clamp 7 is force-fed, the washer 12 is bent and under the state of holding the head bar so as to carry out the force-fed fixing via a steel ball 8 between the carriage 4 and the head clamp 7. The magnetic head is fixed to the carriage at a constant pressure by expanding or contracting of the washer 12 with its spring property to cope with size variations caused by the environmental temp. change due to differences among individual materials in coefficient of expansion. By this method, since an effect of residual screw torque in case of using a screw is not received, misalignment of the magnetic head is hence eliminated.

Abstract: PURPOSE:To enhance maintenance workability by recording various troubles generated in a plate making mechanism and a printing mechanism or the use frequency of expendables on a IC card. CONSTITUTION:When a power supply is closed in the OFF state of a printing press while the ADF key of an operation panel 9 is pushed, the number of the IC card 5 inserted in a slot 7 is displayed.

Title: Aluminum fin material suited for pipe expansion
Inventor: MIYAKI YOSHIMITSU
IPC: F28F21/08
Filed: 1987-12-24
Abstract: PURPOSE:To obtain an aluminum fin material which is suited for pipe expansion because of the lack of the contacting phenomenon at the time of pipe expansion by limiting the average surface roughness and the contact angle with the press lubricant. CONSTITUTION:Although there are various factors affecting the contacting phenomenon, the most significant factor is to reduce the friction as much as possible between the aluminum fins, and the average surface roughness of the aluminum fin material should be 0.03-0.30mum in Ra. When Ra exceeds 0.30mum, it is still effective against the contacting phenomenon, but is adversely affects the productivity. The contact angle with the press lubricant should be less than 15 deg.. When the contact angle exceeds 15 deg., the press lubricant shows poor setting property, causing a greater friction and the adhering phenomenon. By this constitution, there will be no contacting phenomenon at the time of the pipe expansion, and a beautiful cross fin type heat exchanger can be manufactured.

Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To improve application efficiency of system by detecting whether or not a solar battery can generate the power after starting the snow melting operation and then stopping the snow melting operation, when power generation becomes possible. SOLUTION: A snow melting control apparatus 3 detects with a microcomputer 10 whether or not the solar power generating system 1 can generate the power, after the snow melting operation is started, based on the direction of current flowing into the strings 51 to 53 of the solar battery 2 and the detected values of a plurality of current sensors 91 to 93 for detecting the values of such a current. When the direction of the current flowing into the string 51 to 53 and the detected value of the plurality of sensors 91 to 93 for detecting the value of such current becomes 0 Amp or more, the snow melting operation stops because the power generated by the solar battery 2 exceeds the power required for the snow melting, and the solar power generation system 1 is in the condition to generate the power, thereby starting normal power generating operation. Accordingly, system application efficiency can be enhanced.
