Title: Controlling device for synchronous motor
Inventor: NAKANO TERUO
IPC: H02P6/16
Filed: 1980-08-12
Abstract: PURPOSE:To enable the use of the output signal of an optical position detector as the phase sinusoidal wave current reference signals of a synchronous motor by varying the quantity of light of a light source of the optical position detector for detecting the rotating position of the motor. CONSTITUTION:A speed controlling circuit 7 applies a current reference DC signal responsive to the deviation between the speed reference signal from a speed reference generator 6 and the speed signal of a synchronous motor 3 detected by a tachometer generator 5 to the light source 4-1 of an optical position detector 4. After the light emitted from the light source 4-1 is relfected on a reflector provided on the surface of a rotor 4-2 coupled directly to the shaft of the motor 3, it is detected by a photodetector 4-3. In this manner a photoelectric converter 8 can output a sinusoidal current reference signal having both the rotary position detecting signal of the motor 3 and the current reference signal to current controlling circuits 12-1- 12-3.

Title: Method for lubricating rolling flanged shape steel
Inventor: MIURA YOSUKE
IPC: B21B45/02
Filed: 1992-04-28
Abstract: PURPOSE:To reduce the wear of a roll surface while keeping a high accuracy rolling by rolling a material to be rolled as a part large sliding quantity and the most violent in the wear of the roll surface between the roll and the material to be rolled is lubricated and the remaining part is left non-lubricated. CONSTITUTION:When an H-beam is rolled by vertical rolls 2, 3 and horizontal rolls 4, 5 of a universal mill, lubricant is injected from 6a, 7a to roll surfaces 8a, 13a, in the case of the X rolling direction, high pressure water is injected from 10a, 11a to roll surfaces 12a, 13a in the radial directions of the horizontal rolls. Consequently, since lubricant acts effectively on an area (a) only where a sliding quantity between the roll surface and the material to be rolled is large, a rolling stop time is not generated and the life of the roll is prolonged. When the rolling direction is a reverse pass, naturally the lubricant is injected from 6b, 7b toward 8b, 13b and the high pressure water is injected from 10b, 11b to 12b, 13b.

Title: Water-cooled heat pump with waste heat receiver of lake or pond
Inventor: ADACHI HIDEO
IPC: F25B27/00
Filed: 1988-05-07
Abstract: PURPOSE:To enable a stable operation to be carried out without being influenced by a condition of surrounding atmosphere by a method wherein non-freezing liquid is applied in a radiating circuit of an evaporator and the liquid is heat exchanged with water having a temperature of 4 deg.C through a heat exchanger disposed in a lake or pond at a depth blow a specified depth. CONSTITUTION:Hot water having a temperature of about 45 deg.C is supplied to a condensor 1 of a water-cooled heat pump and to a thermal load 5 through a circulation pump 3, the hot water is cooled to 35 deg.C in response to the load then circulated back. Cold water of about -2.5 deg.C is supplied to a heat absorbing side through a circulation pump 4, heat exchanged within water of 4 deg.C, heated up to 2.5 deg.C and returned back. An in-water type heat exchanger 6 is one closed circuit in which some pipes are arranged in a vertical direction and upper and lower ends are bent. Water cooled by this heat exchanger floats up due to a convection flow before reaching a freezing temperature of 0 deg.C and so there is no oppotunity to adhere an ice to a pipe wall. In this way, since water temperature at a place of water depth of less than 5m even at a lake of which surface is freezed is almost stable, this is a stable heat source acting as a depositing heat source and further a water-cooled heat pump can be operated in a stable manner.

Title: Mig and mag pulse arc welding method
Inventor: YAMAMOTO HIDEYUKI
IPC: B23K9/09
Filed: 1989-04-29
Abstract: PURPOSE:To reduce the quantity of generation of spatters and to improve a bead shape by applying gradually a short-circuit release current after continuation of a short circuit during a base current period exceeds a preset value and returning a short-circuit release current value to a base current value after an arc being generated. CONSTITUTION:When the short circuit is detected during the base current applying period, a timing action of a short-circuit release current applying delay timer 31 is started by a short-circuit discrimination signal S3. When the arc is generated while duration of the short circuit is in the set time of the timer, the timer is returned and the short-circuit release so current is not applied leaving the base current value as it is. When duration of the short circuit exceeds the set time of the timer and the arc is not generated during that time, a short-circuit release current applying signal S4 is outputted to a function generation circuit 32 from the timer. The short- circuit release current determined by a current control signal S5 of the circuit 32 is supplied to a consumable electrode 4 from a short-circuit release current power source 33 to generate the arc. An output signal S1 of an output voltage instantaneous value detection circuit 23 is outputted to a changeover circuit 34 to return to the base current value from the short-circuit release current value.

Title: Feed water means of pump bearing
Inventor: KAMATA KUNIO
IPC: F04D29/58
Filed: 1981-07-17
Abstract: PURPOSE:To improve efficiency of a pump by forming a cooling water passage which communicates with an outlet pressure part of an impeller at a certain stage in the center of a pump shaft therethrough and making a feed water bore which branches from the passage through a bearing for cooling it, thereby reducing a loss of pressure water. CONSTITUTION:By rotating an impeller 1, water is sucked from a feed water port 12 and boosted. The boosted water passes through a dischare passage 14 and is then released to a discharge port 15. Cooling water is supplied from a cooling water passage 17 in communication with a certain-stage impeller's outlet pressure part which is located at the suction side of the pump, a pressure being boosted to an insufficient value which is however satisfactory for cooling the bearing part. The water is further carried to cool the bearings 10a and 10b and then passes through a return tube 13 before returned to the suction side of the pump. As mentioned above, the pressure water of the impeller 1 which is not boosted completely cools the bearings 10a and 10b and a motor 9. Since the pressure water at the back of the impeller is not repeatedly used, a loss of the pressure water is minimal and efficiency of the pump is thereby improved.

Title: Jig for heat treatment
Inventor: ISHII MAKOTO
IPC: C04B41/87
Filed: 1985-05-23
Abstract: PURPOSE:To prevent the generation of a crack and a pin hole in an SiC coating layer even by repeated use by specifying the quantity of carbon not reacted which is made to be contained in the SiC coating layer formed onto the surface of a graphite base material. CONSTITUTION:In a high for heat treatment forming an SiC coating layer on the surface of a graphite base material, the coating layer is measured by the Ka wire of Cu in X-ray diffraction, and carbon not reacted is made to be contained in the coating layer so that the ratio Ic/Isic of the diffraction peak value Ic of the 002 face of carbon to the diffraction peak value Isic of the 111 face of SiC reaches 0.005-0.200. The generation of cracks due to a thermo cycle cannot be prevented when Ic/Isic is less than 0.005, and carbon not reacted in an SiC crystal reacts with a product such as a contacting silicon wafer when it exceeds 0.200. Accordingly, Ic/Isic is brought to 0.005-0.200, thus obviating the generation of cracks and pin holes and the like.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily check the outputs of drivers in a substrate state by outputting the check outputs of the respective outputs meeting the respective outputs from driver circuits via data lines and switching elements to output terminals for checking. SOLUTION: X driver output check circuits 4 consist of the switching elements 12 to 14 and their control inputs and outputs 26. The signals for one line of image data may be fetched from the outputs 25 when X drivers 2 are operated in the state of putting such input signals that close all of the switching elements 12 to 14 into the inputs 25. The abnormal defects, if any, existing at the discontinuous points and voltage levels of these signals are indicative of the fact that the operation of the row meeting the timing is defective. The Y drivers also successively select scanning lines 9 to 11 but since the driver outputs are binary values of HL, the Y driver check circuits 5 may be composed of the switching elements 15 to 17 to be controlled by these signals and their inputs and outputs 27, 28.
