Title: Electric water heater
Inventor: TANAHASHI TAKASHI
IPC: F24H1/10
Filed: 1982-11-08
Abstract: PURPOSE:To make possible to changeover the wattage with only one sheath heater, and contrive to improve the compactness, low cost and specific performance by a method wherein a diode and a wattage changeover switch is provided with a sheath heater in series. CONSTITUTION:A thermal cutout TC is usually closed, a pressure switch PS closes an electric circuit by the water pressure due to the opening of a valve V. When a wattage changeover switch WS is connected with a terminal, (n), a sheath heater H is directly electrified with the same commercial alternating electric current power which is connected to power source terminals N, L, then an apparatus becomes at a large wattage condition. Conversely, when the wattage changeover switch WS is connected with the terminal (d), a diode D is inserted between the sheath heater H and the power source terminal L, the sheath heater H is electrified with half-wave rectified commercial alternating electric current power, then the apparatus becomes at a small wattage condition. The cooling of the diode D is performed by installing of the idode D on the water passage at the inlet side of a tank T, accordingly, the more effective cooling can be performed than the cooling of usual radiating fin.

Title: Multicolor image formation device
Inventor: TAKAHASHI YOSHIKAZU
IPC: G03G15/06
Filed: 1991-08-06
Abstract: PURPOSE:To obtain a multicolor image of high picture quality which is not disordered and free from color mixture when development is repeated several times on a photosensitive body where a toner image is already formed by controlling the voltage of the electrostatic charger in a rear stage so that a recovery potential after a developing process in a front stage fills the difference from the development bias in a developing process in the rear stage. CONSTITUTION:Image recording parts 5-8 are arranged in order along the surface of the photosensitive body 3. The photosensitive body 3 is charged electrostatically up to a potential VH in a 1st electrostatic charging process and then the potential of an exposed part drops to VL in the exposing process and is developed with black toner, so that the surface of the black developed part rises slightly. In a 2nd electrostatic charging process, the black developed part is raised up to the recovery potential VR and then the potential of the exposed part drops to VL in a 2nd exposing process; and a developing bias VBias is applied in a 2nd developing process to develop the exposed part with red toner. In this case, the voltage of the electrostatic charger in the rear stage is so controlled that the recovery potential VR after the developing process in the front stage fills the difference from the developing bias VBias in the developing process in the rear stage.

Namely, the orthogonal three-dimensional coordinates X, Y, and Z of the masking area and the three-dimensional coordinates of view point are specified. A controller stores pasted images with mutually different patterns corresponding to respective parts of a house. Then the controller converts the orthogonal three-dimensional coordinate data of (x), (y), and (z) of the specified pasted images to data of the orthogonal three-dimensional coordinates of X, Y, and Z so that the specified pasted images and specified masking area are superposed on each other. Further, the controller maps the pasted images converted to the data of the view point coordinate system in the masking area.

Title: Cassette type storage device
Inventor: ISHII TAKATOSHI
IPC: G11C5/00
Filed: 1982-11-12
Abstract: PURPOSE:To protect data completely and local destruction by backing up a memory element and its peripheral circuit by a battery, and holding a device at low impedance and increasing electrostatic dielectric strength. CONSTITUTION:This includes not only a memory 1, but also a memory control circuit 21 by increasing the range of a battery backup. The circuit 21 consists of CMOS elements and when the battery backup is carried out, those elements are placed in a stand-by state and their ON/OFF states are fixed to flow an extremely small current. At this time, the CMOS elements are in the stand-by state, but the insides of the elements are switched to the low impedance of GND or an electric power source, so the circuit itself is held at the low impedance. Thus, the electrostatic dielectric strength is increased. When the power source is off or when no pack is inserted into the main body, the voltage is held almost at 0V because of the presence of a resistance 55. Thus, data protection control in hot-line insertion and extraction is secured.

Abstract: PURPOSE:To improve the working accuracy and to prolong the service life of a tool by forming a hardened layer through a discharge hardening processing on a surface layer part of the top face of a projecting part of a chamfer part of the tool. CONSTITUTION:On forming surfaces opposed to each other of thread rolling flat dies 12, 14, irregularities corresponding to a screw thread 26 of an object to be worked 10 are provided, and in its chamfer part 30, a surface hardened layer is formed on the surface except a V-groove 28 by a discharge hardening processing. The discharge hardening processing is executed through an electrode of a carbide substance such as WC. At the time of thread rolling, since the surface hardened layer is formed in a tool bitten into the outside peripheral surface of the work to be worked 10, its surface roughness is rough moderately and a slide is prevented. Also, peeling of the projecting part on the thread rolling working surface is obviated, and also, a slide effect by the high wear resistance of the hardened layer continues for a long period. In such a manner, the accuracy for thread rolling is improved, and the service life of the tool is also prolonged.
