Title: Stationary vacuum cleaner
Inventor: NAKAJIMA KINSAKU
IPC: A47L5/38
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To discharge out of the body case the rainwater that infiltrates into it by forming an opening in communication with the intake port and the motor blower, and installing, in a small hole on the bottom face of the dust collecting case, a drain valve that closes the hole when the blower is in operation and that opens it when not in operation. SOLUTION: With the hand switch turned on that is attached to the dust collecting hose having a suction piece, and with an electric blower 25 thereby rotated, the vacuum cleaner body 1 starts sucking the dust through the suction piece. The air containing the sucked dust is drawn into a dust collection filter 54 through a suction hose, connecting pipe 44, and intake port 46. In this case, a water drain valve 81 is installed in a small hole 82 drilled on the bottom plate 11 of the dust collecting case 10. This drain valve 81 is open when the blower 25 is not in operation, so that water is drained into the dust collecting case 10. On the other hand, when the blower 25 is in operation, the degree of vacuum increases in the dust collecting case 10, closing the valve 81 through a negative pressure in the case 10, and preventing the outside air from entering through the small hole 82.

Abstract: PURPOSE:To start a discharge lamp certainly even in case once dropped power supply is recovered by restitution and changing-over is made from an emergency power supply to the normal power supply by performing power supplying to a timer means for a control means, which changes the output of the first high frequency wave generating device, through a changeover means. CONSTITUTION:When a normal power supply 1 is put on, the first high frequency wave generating device 10 oscillates, and the output voltage therefrom is supplied to a discharge lamp 11. When the power supply 1 decays, it is sensed by a sensing means 6, and a changeover means 7 changes over the connection of the lamp 11 from the first device 10 to the second high frequency wave generating device 20. A voltage monitoring device 46 actuates another changeover means 47 and supplies the output of an emergency power supply 40 to the second device 20. Thereby the lamp 11 is lighted with a relatively decreased power. On the other hand, the input power is shut off by the changeover means 7 and the timer means 30-1 of a control device 30 discharges the electric charges quickly through a diode, resistor, etc. If then the normal power supply 1 is restituted, the lamp 11 is changed over form the second 20 to the first device 10 through the action of the means 6, 7, and the operation of the device 20 is stopped by the devices 46, 47.

Title: Magneto-optical disk device
Inventor: TAROUMARU MAKOTO
IPC: G11B11/10
Filed: 1989-02-16
Abstract: PURPOSE:To shorten a period of deteriorating a control performance due to a decrease of electromagnetic force by changing a gain of a servo controller in response to a change of a magnetic field. CONSTITUTION:The subject device possesses a magnetic field detecting means 32 for detecting the intensity and direction of the magnetic field of an electromagnet and a gain control circuit 40 in the servo controller. A magnetic field signal is outputted by the magnetic field detecting means 32 corresponding to the intensity and polarity of the magnetic field generated by the electromagnet, and the magnetic field signal is inputted to a gain control terminal 402 of the gain control circuit 40. The gain control circuit 40 possesses a gain characteristic in inverse proportion to a control input signal of the gain control terminal 402 on an input signal of an input terminal 401. Consequently, the gain of the servo controller is increased according to lowering the magnetic field, and an open loop gain of a servo control system is kept constant except the vicinity of a moment that the magnetic field becomes zero. By this method, the period of incontrollability is shortened.

Title: Microwave oven
Inventor: TAKEI TAMOTSU
IPC: F24C7/02
Filed: 1990-02-16
Abstract: PURPOSE:To prevent a failure in cooking, etc., by stopping operation of an oven function, and performing informing operation when a determining means determines that a detected speed is lower than a target speed. CONSTITUTION:While a microwave oven function is being operated, a rotation speed detector 37 detects a rotation speed of a motor 6, and a determining means of a control circuit 30 determines whether the detected speed is lower than a target speed. When the detected speed is judged to be lower than the target speed M, a failure coping means of the control circuit 30 stops operation of the oven function as well as performs informing operation. That is, if the rotation speed of the motor 6 has dropped or the rotation has stopped due to a deviation of a position where food is mounted with respect to a rotating dish or due to occurrence of a defect of a bearing on the motor 6 and a turning force transmission path, this can be automatically detected and the oven operation can be stopped. Thus a failure in cooking can be eliminated.

Abstract: PURPOSE:To obtain focus information accurately on the basis of the phase shift between light images formed on an image formation surface by light beams which are passed alternately at intervals of one screen through a couple of holes in a luminous flux control plate arranged near the exit pupil of a photographic lens. CONSTITUTION:The luminous flux control plate 23 is constituted of laminating a polarizer 41, light shield member 42, liquid-crystal layer 43, transparent layer 44, and analyzer 45. The couple of holes 24 and 25 are formed in the light shield member 42 and transparent electrodes 46 and 47 are fitted therein. Then, lead wires are led out from electrodes 46a and 47a for applying AC electric fields to the transparent electrodes 46 and 47. Further, the directions of polarization of the polarizer 41 and analyzer 45 cross each other at right angle. Then when AC electric fields are applied to the liquid-crystal layer 43 through the transparent electrodes 46 and 47, the rotations of incident light beams 48 and 49 in the liquid-crystal layer in their directions of polarization are minimized and transmitted light is minimized. When no AC electric field is applied, the plane of polarization is rotated by 90 deg. in the liquid-crystal layer 43 to maximize the transmitted light.

Abstract: PURPOSE:To ensure the quality and to enhance the yield by forming a rear surface composed of a main surface and concavities formed in the main surface, and by forming slopes which are formed inside of the peripheral edges of the tile and which are gradually lowered from higher parts parallel with the peripheral edges, toward the center and the peripheral edges of the tile. CONSTITUTION:The rear surface of a tile is composed of a planar main surface 9 and concave and convex parts 8 formed in the main surface 9, and a straight line-like rear foot pattern given by a height difference between the main surface 9 and the concave and convex parts 8 is extended within a length of 10mm. Recess-like ridges of the concave and convex parts 8 are formed being extended to the side surfaces of the tile 7 so as to promote the discharge of gas generated from a molding body during bisque-firing, from the concave and convex parts 8 to the sides of the tile 7. Further, in the case of bisque-firing a plurality of molding bodies which are stacked one upon another, higher parts 8a of the main surface 9 make contact an underneath molding body so as to inhibit the convex parts from being pressed against the outer surface of another molding body. With this arrangement, concavities and convexities caused by concave and convex rear foot parts and irregularities in the density of sintering, can be prevented from occurring on the front surface of the bisque-fired body, thereby it is possible to prevent a rear foot pattern occurring on the decorative surface of the product tile 7.
