Inventor: MIURA HEIHACHI
IPC: H01J19/44
Filed: 1985-11-25
Abstract: PURPOSE:To equalize a potential gradient still more and make any damage checkable, by embedding an electric conductor layer in the inner part of a ceramic insulating cylinder being set up between electrodes given different potential each, at intervals with one another along the axial direction. CONSTITUTION:Ceramic insulating cylinders 31 and 32 use such one where plural electric conductor layers 33, 33... and 34, 34... at the specified intervals along the axial direction, extending over the whole circumference of the inside. These conductor layers are embedded over the whole circumference of each ceramic cylinder. When voltage is impressed between electrode terminals, equivalent condensers C and C holding a ceramic material or a dielectric in between are formed between these conductor layers embedded in the ceramic inside. Therefore, inside the ceramic insulating cylinder, the impressed voltage is divided by plural equivalent condensers C, whereby almost equal potential gradient distribution is produced in the axial direction. Therefore, an equipotential lie is improved to be almost equal distribution along the axial direction at a part of the ceramic insulating cylinder, so that partial strong field concentration is relieved. Thus, discharge and damage to the ceramic insulating cylinder are checked.

Title: Jet bubble injection nozzle
Inventor: KITA SHIGEHIRO
IPC: A47K3/00
Filed: 1989-10-06
Abstract: PURPOSE:To increase an impact force of a bubble jet with an increase in amount of air to be mixed thereinto by arranging an air chamber which is adapted to mix air into a water jet flow by an ejector effect to suppress an increase in an output of a circulation pump with the shape of an opening made convex and concave at an outlet of a diffuser. CONSTITUTION:Bath water from a circulation pipe 7 increases in water passing speed at a choking section 5a of a diffuser 5 and jetted out into an air chamber 5c at a high speed at an outlet 5b to be injected into a bath tub via a path 6a with a fixed section at a discharge port 6. When the bath water passes through the air chamber, a negative pressure is generated on the outer circumference of a flow B so that air contacting the flow is sucked into the water flow to develop an ejector effect. So, in this case, as means replacing a discharge pressure, a sucking force in mixing of air of the water flow is used. As the sucking force is a negative pressure, the result of a test is obtained that a mixing ratio of the air is increased with an increase in contact area with the air and this is utilized to turn a sectional shape of a diffuser outlet convex and concave from a simple circle, thereby increasing an impact force to a human body with the mixing of large amount of air into the water flow.

Filed: 1991-09-13
Abstract: PURPOSE: To dispense with a permanent magnet to miniaturize an apparatus and to prevent erroneous operation by energizing an inertia element to a preset position by a coil spring. CONSTITUTION: At a time of the collision of a car in a decelerated state exceeding a preset level, the ball 54 of a sensor 10 begins to upwardly move along the route prescribed by a bone 50 against the energizing force caused by a blade 24. When the ball 54 moves upwardly, the blade 24 is bent to come into contact with a blade 22 and a current flows to the mechanism 72 developing an air bag 74 from a battery 70 develop the air bag 74. When the deceleration of the car is large, the ball 54 stops at the bent part 52 of the bone and, when the car stops, the ball 54 returns to the stop position by the repulsive forces of the blades 22, 24. Since a large space is unnecessary in the energizing of the ball 54, the apparatus can be miniaturized.  Since the ball 54 and the blades 22, 24 are constituted of an electrical conductor, the possibility bringing about the erroneous operation caused by connection inferiority is reduced.

Abstract: PURPOSE:To provide the title detector ensuring the striations of compound semiconductor crystal with segregation to be observed throughout the range of wafers, so designed that the higher impurity concentration side of a wafer cut parallel in its growth direction is directed upward and is defined as anode, and an anodic oxidative reaction is made while gradually increasing or decreasing the portion to be dipped into the electrolyte for the wafer. CONSTITUTION:For a wafer 1 (diagonal line portion in Fig. II) prepared by cutting parallel in its growth direction a group III-V or II-IV compound semiconductor, e.g., Sn-doped InP crystal, the tail side (B side) with higher impurity concentration is directed upward and defined as anode by e.g., clipping 2 and dipped, facing to cathode 3 such as of Pt, into an electrolyte in a vessel (electrolytic tank) 7. Thence, voltage is applied between both the electrodes through an electric source 5 to make an anodic oxidative reaction, during this process, the vessel 7 is lowered through a drive 8 to decrease the portion of the wafer 1 to be dipped. In this case, the B side is higher in Sn concentration with the impurities linearly distributed from the lower side towards the B side, thus electric current is always passed through the B side, thereby developing striations over the entire range of wafer.

Filed: 1994-10-27
Abstract: PURPOSE: To make a pointer or dial to be invisible from the outside by matching the peak wavelength of surface reflecting property of at least one or both of the pointer and dial with the wavelength of a smoked glass with low transmissivity. CONSTITUTION: A smoke glass 3 is fixed on a black dial trim plate 12 or a case 7, covering a pointer 1 and dial 2, and it is set in advance as to have spectral characteristics with a specified wavelength and transmissivity. The reflection factor of a reflection layer for specified wavelength becomes high against external optical component having a wavelength of at most 400nm. However, since the transmissivity of the glass 3 is low, a light quantity transmitting the glass 3 decreases, so the pointer 1 and dial 2 are difficult to be seen. On the other hand, the reflection factor thereof is 0% against the external optical component having a wavelength of at least 400nm, so the pointer 1 and dial 2 cannot be seen at all. Therefore, in the case where the light is turned off or the external light is strong, the pointer 1 and dial 2 are difficult to be seen.

Title: Ink jet recording device
Inventor: TAKAHASHI KIICHIRO
IPC: B41J2/18
Filed: 1992-10-01
Abstract: PURPOSE:To prevent ink from flowing back to an ink discharge orifice side during a backward movement action in an ink jet recording device equipped with a piston which is installed for recovery treatment designed to discharge ink satisfactorily from an ink jet recording head, then sucks ink from the ink discharge orifice of the ink jet recording head, in response to a forward movement action, and discharges the ink received by suction in response to a backward movement action. CONSTITUTION:The movement of a piston for ink suction is controlled when it is moved back (positions: C to B) for ink discharge following the forward movement action of the piston (positions: B to C) for ink suction. That is, the backflow occurs, when the backward movement action takes place rapidly before a waste ink flow path could be sufficiently secured. Therefore, when the waste ink quantity in a cylinder pump is very large, the piston is moved at low speed, and when almost no waste ink is present, the piston is moved at high speed so that a recovery action is ended rapidly.
