Title: Hot water mixing device
Inventor: SAIJIYOU MASARU
IPC: F24D17/00
Filed: 1981-04-16
Abstract: PURPOSE:To make it possible to obtain a desired hot water temperature by a method wherein in the titled device in which hot water and the city water are mixed with each other to produce warm water of a suitable temperature and the warm water is discharged from a faucet, the mixing ratio of the city water to the hot water is automatically changed in proportion to the flow rate of the warm water through the faucet. CONSTITUTION:As the faucet 6 is opened wider, so the pressure drop at an orifice 7 becomes greater in proportion to the increase of the flow rate of the warm water through an output port 11 and the pressure difference between a chamber 15 and a mixing chamber 19 increases. Thus, due to the increase of the flow rate of the warm water at the output port 11, a diaphragm 13 moves upward against the force of a spring 16 so that a valve body 12 attached to the diaphragm 13 gradually opens an inlet 14 and the city water is flowed into the device from a first inlet 9 through a city water pipe 2 via a pipe 4. The city water introduced into the device is then mixed with the hot water from a second inlet 10 in a variable mixing ratio and the temperature of the resultant warm water flowing from the output port 10 to the faucet 6 is varied in proportion to the flow rate of the warm water at the faucet 6.

IPC: H03M1/10
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To attain test at a high speed with desired resolution by inputting a step-shaped ramp wave, searching an output code by measuring an A/D converter to be tested with a specific input voltage in the first ramp wave, searching an output code by using the middle point of a previously measured specific block as an input voltage, and searching the transition point. SOLUTION: An arbitrary waveform generator 10 D/A converts memory data indicated by an address pointer, and outputs it to an A/D converter 60 to be tested. Also, the address pointer is continuously changed from a CPU 30 so that an arbitrary step-shaped ramp wave can be generated. In the first ramp wave, an output code can be calculated by measuring the A/D converter to be tested with an input voltage in the step width of the least significant bits of the A/D converter 60 to be tested, and in the second and more ramp waves, an output code can be calculated by comparing the previously measured output code and using the middle point of a block in which the adjacent output codes are different as an input voltage. Thus, the transition point of the output code of the A/D converter 60 to be tested can be calculated.

Title: Swash plate type compressor
Inventor: MICHIYUKI HIROMI
IPC: F04B39/00
Filed: 1995-03-17
Abstract: PURPOSE: To improve performance of a compressor by a swash plate structure, light in weight and excellent in durability. CONSTITUTION: The effective slope 44 of a swash plate is recessed in such a state that an annular band 44a narrower than a slide contact area is present in a rotation region Y. A fan-shaped through-hole 47 is formed through on both sides of a surface D-D' passing through the two dead centers of the swash plate 40 and paralleling an axis in such a state to bypass the slide contact area of a shoe. A reinforcing rib 46 extending in a centripetal direction from the annular band 44a is formed on the rotation region wherein a compression reaction force exerted on the swash plate 40 is maximized. This constitution ensures the sufficient strength of the swash plate, reduces the weight of a compressor, and improves performance.

Title: Cinecamera using film cartridge
Inventor: SAKAGUCHI KEIICHI
IPC: G03B31/02
Filed: 1980-05-06
Abstract: PURPOSE: To make this camera usable for both of films for simultaneous sound- recording and exclusive for image recording by automatically changing over the film feed speed for taking to constant-speed controlling and variable-speed controlling.  
     CONSTITUTION: When a film cartridge 1 for simultaneous sound-recording is loaded in the camera and the camera is set in a sound-recording state, a switch 52 is closed and a loop detecting member 24 contacts the loop part of a film 2. When a main switch 46 and a release switch 47 are closed in this state, film-feed motors 40, 7 for sound-recording and taking operate respectively. When the detecting member 24 detects a decrease or increase in the loop of the film 2, it turns OFF or ON a switch 51 which in turn controls the rotating speed of the motor 7, thus the film loop is maintained always at a predetermined amount. When a cartridge exclusive for image recording is going to be used, a switch 52 is open; hence, the motor 7 is subjected to constant-speed controlling by a governor 49. In this way, either of the cartridges may be used.
