Abstract: PURPOSE:To prevent the erroneous detection of pottery or flowing water, precisely detect only the hand, and ensure a sufficiently wide hand washing space within a washing bowl, in an automatic faucet having a hand sensor to automatically start and stop the water discharge. CONSTITUTION:A hand sensor S is arranged in a faucet body 1. Water is discharged slightly downward over the horizontal direction from a spout A2. The hand sensor has a projector and a light receiver. The projector and the light receiver are regulated in such a manner that the directional axis (d) of the area (detecting area) where the projecting area of the projector is superposed on the light receiving area of the light receiver crosses the discharged water flow, and the crossing angle is regularly lower than 70 deg. regardless of the magnitude of the water flow. The start/stop of the discharged water is controlled on the basis of the reflected light level detected by the light receiver.

Title: Electrostatic induction type semiconductor device and current drive type semiconductor device
Inventor: YAMAMOTO MUNEKORE
IPC: H01L29/80
Filed: 1992-12-16
Abstract: PURPOSE:To improve the breakdown strength of an element by improving the resistance to avalanche of the Zener diode built in between a drain and a gate. CONSTITUTION:A p-type guard ring region 7 is made as the anode of the Zener diode between the drain and gate by the PN junction with an n-type epitaxial layer 13, separately from a p-type gate region 15. Moreover, the p-type guard ring region 7 is electrically connected to a gate electrode 19 through a doped polysilicon layer 25 doped in low concentration at relatively high resistance. The voltage of the breakdown current by avalanche is dropped with a high- resistance region 25, and by that amount, the current is limited. For this reason, a large current ceases to flow in the p-type guard ring region, and it becomes hard for current concentration to occur, so the resistance to avalanche improves. Moreover, there is no inflow of a breakdown current to an n<+>-type source region 18, either.

IPC: B65H5/06
Filed: 1987-12-29
Abstract: PURPOSE:To facilitate maintenance and prevent deformation of tray by allowing a sheet transport unit and a sheet exhaust tray to rotate round the some axis, furnishing a restricting means for revolution opening angle, and thereby opening the unit and tray simultaneously.

Title: Heating controller of injection molding machine
Inventor: TOMITA REI
IPC: G05D23/22
Filed: 1987-12-29
Abstract: PURPOSE:To automatically dehumidify the insulating material of a heater, by providing a leakage detector outputting the signal inversely proportional to the magnitude of the leak current of the heater and a voltage controller for controlling the voltage of the heater corresponding to the signal from said leakage detector. CONSTITUTION:A leakage detector 7 detects the leak current of a heater 1 to output the signal inversely proportional to the magnitude of the leak current. For example, when the insulating material of the heater absorbs humidity and the leak current increases, the reduced signal inversely proportional to said increment is contrarily outputted to a voltage controller 8. The voltage controller 8 controls the voltage of the heater 1 corresponding to the signal from the leakage detector 7. That is, when the leak current is increased, the signal inversely proportional to this is inputted and, therefore, the voltage controller drops the voltage of the heater. When the voltage of the heater drops, the leak current of the heater is reduced and the generation of an electric leak accident is prevented and the insulating material of the heater is dehumidified by the self-generation of heat of the heater.

Abstract: PROBLEM TO BE SOLVED: To provide purifying function and keep the antifouling property of a mirror by forming a surface layer containing photocatalytic titanium oxide and an inorganic substance on the surface of a mirror finished metallic base material, and photo-exciting the photocatalytic titanium oxide. SOLUTION: As a mirror finished metallic base material iron, cast iron, or non-iron metal is used to form a surface layer containing an inorganic binder and a photocatalytic titanium oxide. For example, 2 g of anatase titanium oxide having the inorganic binder mixed thereto and 1 g of isopropyl alcohol are mixed together followed by stirring, and the resulting mixture is applied to a surface-purified aluminum alloy plate in two installation of substantially an equal quantity at an interval of 10 minutes, and dried for 20 minutes by a driver held at 50 deg.C to form the surface layer. This photocatalytic titanium oxide is photo-excited, whereby a toxic material such as an organic matter, compound, or nitrogen oxide touched to the surface layer is oxidized. Accordingly, the antifouling property of a mirror with purifying function free from breaking and contamination can be kept.

Abstract: PURPOSE:To send smoothly the TE11 mode of a transmission wave to a radial guide path by providing a conical conductor block at the rear middle part of a slot plate so that its apex is coincident with a guide axis of a circular waveguide. CONSTITUTION:A conical conductor block 14 is provided at the rear middle part of a slot plate 7. Thus, a capacitive component is added to the slot plate to make the admittance close to a characteristic admittance of the feeding system and a space in which a harmonic mode wave is caused is filled to exclude the disadvantage by the production. That is, a large reflection loss is reduced by the parallel admittance with respect to an input fundamental wave from the waveguide and the enclosed resonance of the harmonic mode wave is eliminated. Furthermore, the apex angle of the conical conductor block 14 is selected to be 90 deg. and the height is set to the height of the radial guide line 5 and then optimized. Thus, the mode TE11 of the supplied transmission wave is smoothly sent to the guide line 5.
