Title: Method for detecting abnormality of oscillation in continuous casting mold oscillating device
Inventor: YAMASHITA HAJIME
IPC: B22D11/16
Filed: 1990-07-23
Abstract: PURPOSE:To surely detect abnormality of an oscillating frame at early time by measuring amplitudes at the times of oscillating the oscillating frame at high velocity and at low velocity in a continuous casting mold oscillating device, obtaining displacing ratio based on the formula and deciding as the abnormality in the oscillation when the displacing ratio exceeds the fixed value. CONSTITUTION:Under empty condition, which molten steel is not supplied in the mold 1, the oscillating frame 2 is oscillated at the high velocity and successively, this is oscillated at the low velocity to obtain the displacing ratio in the oscillation with the formula. At this time, if some abnormality of wear and breakage, etc., to link mechanism in the mold oscillating device is developed, transmission of vertical movement of a rod 12 for driving with driving mechanism to the oscillating frame 2 becomes imperfect. In this result, the amplitude at the time of oscillating in the high velocity is not so large difference as that at the normal time, but the amplitude at the time of oscillating in the low velocity becomes remarkably smaller than that at the normal time and the displacing ratio in the oscillation becomes remarkably large compared with the displacing ratio at the normal time. Therefore, in the case the displacing ratio at the time of developing the abnormality in the link mechanism is set, e.g. to 10%, when the displacing ratio exceeds this, the development of abnormality in the oscillation can be surely detected.

Title: Reflector and reflection type liquid crystal display device
Inventor: TAKATSUKA TOMOMASA
IPC: G02B5/08
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To impart a reflector reflection angle of a wide range and to improve the reflection efficiency, by constituting the reflector by successively joining many grooves having flatly curved shapes on its front surface. SOLUTION: The reflector 1 is constituted by successively joining the many curvilinear grooves 3, which are equal in the widths and depths of the respective grooves to the front surface a substrate 2 consisting of a metallic material, such as, for example, aluminum. In the reflector 1, when light is made incident on the reflector 1 from the direction orthogonal with the grooves 3, the surface on which the light falls are curved and, therefore the reflection angle of the light may be made wider than in the case the grooves 3 are rectilinear. The radius of curvature of the curvilinear grooves 3 may be properly set by the size of the display screen of the applied liquid crystal display device.  If, however, the radius of curvature is too small, the effective utilization of the light from the front surface of the screen is not possible and conversely if the radius of curvature is too large, the degradation in the efficiency of condensing the light from the ambient is resulted. The depth of the curvilinear grooves 3 is preferably set at 1 to 3% of the radius of the inner peripheral surfaces of the curvilinear grooves 3.

Title: Cleaning device of electrophotographic copying machine or the like
Inventor: SHIYOUJI YOSHIO
IPC: G03G21/00
Filed: 1982-11-08
Abstract: PURPOSE:To simplify the mechanism of a cleaning device and to reduce the size and weight by providing simultaneously a rotating brush having the same potential with an electrostatic latent image on a photosensitive body to the cleaning device body. CONSTITUTION:Residual magnetic toner T on the surface of the photosensitive drum D after transfer changes to the polarity (-) of the electrostatic latent image by the discharging of a transfer corotron. When the surface of the drum D rotates to reach a destaticizing corotron position together with the toner T, positively discharging is carried out to weaken charges. The toner T which decreases in sticking force is dispersed over the surface of the drum D at the position of a rotating brush 17 by brushing operation. The brush 17 is electrostatically charged negatively to hardly stick the toner T, so a recovery device is unnecessary and the toner T neither falls nor scatters from the brush 17.

IPC: C02F1/32
Filed: 1992-06-30
Abstract: PURPOSE:To economically supply sanitary and safe water to a consumption group non-steadily consuming a large amt. of tap water in an easily controllable manner by guiding the water in a water receiving tank to a sterilizer only when the water in the water reciving tank is stagnated for a predetermined time or more. CONSTITUTION:The water of a water receiving tank 1 is pumped up by a storage pump 2 and supplied to a house-to-house water supply pipe 5 while the integrated flow rate of the water is measured by a flow rate measuring and integrating device 3. The water receiving tank 1 is connected to a sterilizer 4 and the flow rate measuring and integrating device 3 is electrically connected to the sterilizer 4 and a pump 7. For example, the three-hr integrated quantity of the use amount of water in the house- to-house water supply pipe 5 is measured and, when the measured value reaches 4.8m<3> or less, the flow rate measuring and integrating device 3 sends a signal to start the operation of the pump 7 and the sterilizer 4. When a predetermined sterilizing time is elasped or a flow rate is restored to a definite value, a signal is again sent from the flow rate measuring and integrating device 3 to stop the sterilizer 4 and the pump 7. When the use amount of water is a definite value or less for a long period of time, a series of these operations are repeatedly performed.

Title: Eprom
Inventor: NAKAMURA YASUHIRO
IPC: G11C16/04
Filed: 1986-08-22
Abstract: PURPOSE:To improve the efficiency of writing by providing a substrate voltage generating circuit made to the state of operation selectively in writing operation in an EPROM and applying a negative substrate voltage to a semiconductor substrate at the time of the writing operation of the EPROM. CONSTITUTION:A substrate back bias voltage generating circuit VbbG made to the state of operation selectively at the time of a writing operation mode is provided, and negative substrate back bias voltage -Vbb is supplied to the semiconductor substrate of an EPROM. In such a case, the value of substrate back bias voltage -Vbb is made to about -2V which is close to the central value of substrate potential Vsub at which write efficiency Ew becomes flat. Thence, hot hole induced in the channel part of an FAMOS transistor is absorbed through a semiconductor substrate P-SUB, and even when the substrate potential Vsub is raised by the voltage drop of substrate resistance Rs, the substrate potential Vsub does not exceed OV. Accordingly, since high voltage Vpp for writing applied to the drain and control gate of the FAMOS transistor is not lowered substantially, the lowering of efficiency of writing Ew can be prevented.

IPC: G01L21/22
Filed: 1984-09-18
Abstract: PURPOSE:To obtain a small-sized vacuum sensor which is tolerant to a shock and has superior reliability by using a crystal resonator by selecting the cutting angle of the resonator which provides minimum force sensitivity regardless of the shape of the resonator. CONSTITUTION:The torsional-mode crystal resonator 1 has both its end parts 3 supported fixedly on a support pedestal 2 with an adhesive 4, etc. The support pedestal 2 is made of an insulating material such as ceramic. Consequently, this resonator becomes tolerant to disturbance, specially, impact force unlike a cantilever type. Then, the cutting angle of the resonator 1 is selected within such an angle range that a Y plate is rotated by 5-55 deg. around an X axis as an axis of rotation, and consequently the minimum force sensitivity is obtained regardless of the shape of the resonator. Namely, stress to the resonator 1 originating from temperature variation is minimized by selecting the cutting angle of this resonator 1.
