Title: Thin film magnetic head and its manufacture
Inventor: SHIBAYAMA YUKO
IPC: G11B5/31
Filed: 1988-06-24
Abstract: PURPOSE:To increase the lifetime of a thin film magnetic head together with improvement of the reliability by forming a vertical side wall surface and a back wall surface following the gap zero level at a lower core front part and setting the height of the back wall surface at a level lower than the height of the side wall surface or forming the back wall surface as a gentle slop surface. CONSTITUTION:The projecting side surface 2a2 of a front (tip) part is patterned approximately vertical by an extent equivalent to the track width or up in the fixed depth. Thus the highly accurate control is possible with the track width. While the etching depth of a gap termination part (back wall surface) 2a4 is set at a level less than the depth of a gap forming part (both side surfaces) 2a. Otherwise the part 2a4 is patterned in a gentle taper form. Thus the core volume is increased and therefore the magnetic saturation phenomenon can be reduced. In particular, the cross sectional area is increased for a neck part (a place immediately following a position 2C showing the zero level of the gap depth) that gives the grave influence to the magnetic saturation. Thus the occurrence of the magnetic saturation can be avoided. As a result, the reliability is improved for the recording/reproducing characteristics.

Title: Combustion controller
Inventor: SAKURAI TOSHIO
IPC: F23N5/26
Filed: 1989-06-16
Abstract: PURPOSE:To enable combustion quantity to be easily controlled regardless of variations in load temperature, by providing a means for maintaining the temperature of a load at an apparently constant value, independent of a temperature detected by a temperature sensor. CONSTITUTION:When a pushbutton switch 11 is not operated, a microcomputer 5 performs a normal combustion quantity control, and displays room temperature or a set temperature on a display device 10. When the switch 11 is depressed once, the microcomputer 5 fixes the room temperature at 22 deg.C, irrespective of a temperature detected by a temperature sensor 4, then controls combustion quantity according to the temperature difference between the apparent room temperature (22 deg.C) and the set temperature (10-30 deg.C), and displays the combustion quantity on the display device 10. Therefore, when a certain set temperature is given at the time of shipping from a factory or at the time of adjustment in service, the combustion quantity is constantly fixed even upon variations in room temperature.

Title: Air conditioning device
Inventor: SETO MAKOTO
IPC: F24F11/02
Filed: 1986-07-02
Abstract: PURPOSE:To individually control the operation of plural sets of the same type machine by providing a transmitting means for feeding codes different in length to plural air conditioning machine main bodies and a receiving means for selecting the proper code length capable of receiving. CONSTITUTION:At the time of operating two sets, the receiving code length of the air conditioning machine main body is set to the respectively different code length according to the opening and the closing of a change over circuit 8. The transmission codes different in the code length of A bits or (A+1) bits are transmitted to the respective air conditioning machine main bodies to control. In such case, since the air conditioning machine main body receives only the code of the code length set by itself, if the respectively different code length is transmitted from a remote controller, the plural sets of the air conditioning machine bodies of the same machine type in the same room can be respectively individually controlled.

Filed: 1993-06-25
Abstract: PURPOSE:To control boiler outlet steam temperature adequately responding to load change by controlling the concentration of ammonia supplied to the exhaust gas boiler of an ammonia-water mixed liquid cycle. CONSTITUTION:The inlet feed-liquid ammonia concentration of the boiler 2 of an ammonia-water mixed fluid cycle is detected to operate a condensate pump outlet feed-liquid flow rate adjusting valve 8 so that feed-liquid has ammonia concentration wherein the outlet steam temperature of the boiler 2 becomes a prescribed value, that is, when the outlet steam temperature of the boiler 2 becomes higher (lower) than the prescribed value, the outlet feed-liquid flow rate of condensate pump 6 is increased (reduced) to increase (reduce) the condensate flow rate of low-ammonia concentration to lower (increase) the concentration of feed-liquid ammonia after mixing. Consequently absorbed heat from the boiler 2 is reduced (increased) to lower (rise) the outlet steam temperature of the boiler 2 to return to the prescribed value, controlling the outlet steam temperature of the boiler 2 which properly corresponds to the load change.

Title: Fuel combustion burner
Inventor: ROORANDO BUINSENTO HOREISHIYOO
IPC: F23D14/74
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of generating resonance combustion noise with a comparatively high and sufficient turn down ratio by a method wherein a flame supporting body is extended into lengthwise direction to separate a dispersion area while a shielding layers, precluding the penetration of a fuel/air mixture from the upstream side of a flame supporting body to the downstream side of the same in this area, is provided. SOLUTION: A flame supporting body 20 is provided with dispersion areas 22 consisting of burner flame ports 13 having an equal size. The burner flame ports are provided with the configuration of straight cylinder, penetrating the supporting body from the upstream side to the downstream side 214 and ending at the downstream side 24 while becoming the opening 25 of the flame supporting body. The linear parts 21 of the supporting body materials are extended lengthwisely between the dispersion areas 22 to form shielding means 26, separating the areas from each other. On the other hand, the shielding means 26 increases also the maintaining force of flame in the downstream side 24 of the dispersing areas 22 when the heat output load of the burner is big.  Further, the shielding means 26 precludes the passage of a fuel/air mixture from the upstream side of the supporting body to the downstream side 24 of the same in a part or area between dispersion, areas 22.

Filed: 1986-06-30
Abstract: PURPOSE:To hold the output of a laser diode at a regulated level automatically, by providing a duty control means, a smoothing means, a current conversion means, a comparison means, and a central control unit. CONSTITUTION:The duty control means 2 varies the pulse duty of a laser power control signal based on a control signal inputted from the central control unit 1, and outputs the signal to the smoothing means 3.

Abstract: PURPOSE:To prevent the generation of trouble caused by recording without paper, by detecting that a recording chart has reached the recording position, and attaining recording. CONSTITUTION:When the recording sheet 3 is inserted to upper/lower guides 11-3, 11-4 for facsimile recording, a sheet detector 24 detects it and a detecting signal is transmitted to a control section 40. A solenoid 25-3 is driven via a driving circuit 41 after the tip of the sheet 3 has reached sufficiently the recording position, and the sheet 3 is clipped between roller pairs 25-1 and 25-2. The control section 40 drives a motor M via a driving circuit 43 to carry the sheet 3 to a position pressed with a recording head 4 between a platen 5 and a transfer sheet 2. When the sheet 3 is transmitted normally to a prescribed position, the roll 25-1 rotates for a prescribed number. A revolution number detector 25-4 reports the rotation of the roll 25-1 to the control section 40. The control section 40 controls the recording head 4 via the driving section 42.
