Title: Solar heat absorber
Inventor: YAMAKAWA SEISHIROU
IPC: F24J2/48
Filed: 1980-09-06
Abstract: PURPOSE: To reduce the deterioration of selective absorbability and prolong the service life by a method wherein a blank, the surface layer of which consists of a selective absorption film, is treated with a chelating agent which makes a chelate compound with copper.  
     CONSTITUTION: The base material 1 of the solar heat absorber consists of a substrate 11 made of material not containing copper such as iron, plastics or the like and the blank 12 made of copper or copper alloy being formed in a layer over the substrate 11. And the surface layer of said blank 12 is converted into the selective absorption film. A copper-chelate layer 13 is formed over the surface of the film 121 by being treated with the chelating agent and further protected with a protective film 14 applied over the layer 13. The thickness of the selective absorption film 121 is rendered to be 0.1W2.5 micrometers. Due to the structure described above, the deterioration of the selective absorption film 121 caused by the oxidation of copper can be prevented effectively.

Title: Torque controlling method for motor-driven hydraulic pulse cutting tool
Inventor: KOSEKI HIROSHI
IPC: B25B21/02
Filed: 1995-04-25
Abstract: PURPOSE: To make precise screw tightening with a low reaction force by performing A/D conversion upon waveform treatment of the load current waveform in a motor at the time of screw fastening, sensing the displacement amount of the digital signal obtained therefrom, and controlling the screw tightening torque. CONSTITUTION: When a motor 2 is driven under control of a controller 6, the torque of the motor 2 is converted into shock pulses by the hydraulic pressure in a hydraulic pulse part 3, and screw is tightened with the shock pulses. At this time, a pulse similar to the pulsated output torque appears in the motor load current waveform. Because a point of inflection appears in the rising curve of the thrust force as screw tightening proceeds, the gradient of the rising curve of the motor load current waveform which varies with varing thrust force, is going to be saturated. Therefore, the motor load current is sensed and subjected to A/D conversion upon a waveform treatment, and the digital signal obtained therefrom is fed to a comparator, where the displacement amount of the current waveform is determined, and screw tightening is completed when the displacement amount becomes zero.

Title: Transistor switch unit
Inventor: NOMURA HIROYUKI
IPC: H03K17/10
Filed: 1978-10-12
Abstract: PURPOSE:To balance voltage partial charge by adding a Zener diode in the switching circuit where transistors are connected in series. CONSTITUTION:Assuming that transistor 2a is first turned off in case that transistors 2a and 2b are turned off by driving circuit 1, the voltage of capacitor 4a rises due to diode 5a, however, this voltage rises only up to the approximate half of power source voltage ED because the Zener voltage of Zener diode 10a is slightly smaller than the half of voltage ED of power source 7. Consequently, the voltage across the collector and the emitter of transistor 2a becomes the half of power source voltage ED approximately. A current flowed to Zener diode 10a only makes charge of capacitor 4b fast.
