Abstract: PURPOSE:To easily and securely execute a beam without requiring the assembly and disassembly of a form and a pipe and the setting up and withdrawal of a support. CONSTITUTION:In the case where a beam is manufactured by applying a reinforced concrete slab, a support is removed, and a provisional beam 1 for the beam having a channel steel plate 6 deposited to upper and lower chord members 3 is severally set up at both the sides of the beam 2. Each side forming form 5 provided at both the si.des of the beam 2 is reinforced by the channel steel plate 2 so as to bear up against lateral pressure caused by concrete placing. After the determination of beam dimensions, a tie member 7 is severally bolted to the lower end faces of the chord members of both the provisional beams 1 for the beam. In addition, a channel steel plate 9 to reinforce a lower end face forming form 10 provided at a position on the lower end face of the beam so as to bear up against the weight of the concrete is spread on the upper face of the tie member 7. After that, the lower end face forming form 10 for the beam 2 is spread, and the concrete is placed in a space enclosed by the both side forming forms 5 and the lower end face forming form 10.

Title: Rock drill
Inventor: SIEGENTHALER MAX
IPC: E21B1/26
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a rock drill simple in constitution with few restrictions on use (with wide application) and constituted in such a way that an impact unit automatically stops in the case of drill steel becoming unmovable since impact frequency changes in proportion to the rotating speed of a rotating motor. SOLUTION: A rock drill 9 is provided with a rotating motor 10 and an impact unit 11 with an impact valve 17. A rotating unit and the impact unit 11 are operated by separate valves 39, 46 in a control unit 34, and the impact frequency of the impact unit 11 is interlocked with the rotating speed of the rotating motor 10 so that the impact unit 11 stops when the rotating motor 10 stops. This interlocking is attained without mechanical clutch mechanism by using a fluid driving means. At the time of disassembling a drill bar, an unmovable thread can be shaken in a loosened state from the impact unit 11 by manually bypassing fluid coupling. In the case of the drill bar being unmovable in a drill hole, the same constitution is applied thereto.

Title: Detector for deterioration of lubricating oil
Inventor: NISHINO NORIAKI
IPC: F01M11/10
Filed: 1989-10-30
Abstract: PURPOSE:To judge the deterioration of a lubricating oil by disposing a piezoelectric element in the lubricating oil, impressing an AC voltage thereto and measuring the impedance thereof. CONSTITUTION:The piezoelectric element 14 is disposed in the lubricating oil 12 packed in a container 10. The element 14 oscillates when an AC voltage generator 20 impresses the voltage of variable frequencies to the element 14. The impedance of the element 14 is measured by the measuring voltage of a voltmeter 22 when the resistor R inserted in series between the generator 20 and the element 14 is set sufficiently larger than the impedance of the element 14. The resonance frequency to minimize the impedance of the element 14 has one-to-one correspondence to the viscosity of the lubricating oil. Whether the viscosity of the lubricating oil 12 is adequate or not is discriminated and the deterioration is judged if whether the resonance frequency is maintained in a prescribed range or not is detected by a control circuit 24 constituted as a microcomputer system.

Abstract: PURPOSE:To provide a storage type liquid heater capable of constantly supplying a necessary liquid to be heated and of miniaturizing a tank by providing auxiliary control means for controlling the operation of an auxiliary heater in accordance with the detection output of an auxiliary sensor based on the quantity of heating to be specified. CONSTITUTION:The temperature of hot water and the operational time zone of a main heater 2 are preset by a setting part 9. When the current time is judged to be in the operational time zone of the main heater 2 in a judging part 10, an auxiliary temperature control part 14 turns off an auxiliary heater 4. Furthermore, a main temperature control part 11 judges whether the temperature of hot water due to the detection output of a main sensor 3 is lower than a preset temperature from the setting part 9 or not. When the result of the judgement is 'YES', the main heater 2 is turned on, whereas it is 'NO', the main heater 2 is turned off. By this operation, hot water of 85 deg.C or higher is produced in a tank 1. Further, when the temperature of hot water is judged to be not within the operational time zone of the main heater 2, the main heater 2 is turned off. Operating means 13 selects a first auxiliary sensor 5a when the hot water securing quantity is large, and a second auxiliary sensor 5b when it is small. The auxiliary temperature control part 14 judges whether the temperature of hot water is lower than the set temperature or not. When it is 'YES', the auxiliary heater 4 is turned on, and when it is 'NO', it is turned off.

Abstract: PURPOSE:To secure a film thickness of a conductive layer by forming an opening so as to be large at the upper part and so as to be small at the bottom and to prevent a disconnection by a method wherein an insulating layer whose energy speed is fast at the upper part and slow at the bottom and whose main raw material is tetraethoxyorthosilicate is formed, a resist film for contacthole formation is patterned on it and, after that, the insulating layer is etched by an isotropic etching means. CONSTITUTION:A first silicon oxide film 2a is deposited; it is heat-treated. A second silicon oxide film 2b is deposited on it; it is not heat-treated. Thus an insulating layer 2 of two layers is obtained. A photoresist film 1 for contact- hole formation is patterned on it; the insulating layer 2 is etched by an isotropic etching means. In this case, since an etch rate of the first silicon oxide film 2a is slower than that of the second silicon oxide film 2b, a recessed part 15 which has been so opened as to be wide at the upper part and narrow at the bottom is obtained. In succession, a recessed part 16 is formed by an anisotropic etching means until it reaches an N-diffusion layer 3; a contact hole 5 which is so opened as to be large at the upper part and small at the bottom is obtained.
