Title: Control device for electric water-heater
Inventor: TOMOTA SHINICHI
IPC: F24H1/18
Filed: 1990-08-07
Abstract: PURPOSE:To safely boil water by manual operation even during the damage of a circuit in a microcomputer, by providing a manually operated switch which is, in parallel, connected to a second relay circuit, and is, in series, connected to a overheat-preventing device. CONSTITUTION:A manually operated switch 9 is, in parallel, connected to a second relay 5 and is, in series, connected to an overheat-preventing device 3. When a circuit in a microcomputer 6 is damaged during operation, independent of a signal from a thermistor 2, a contact point 5a for the second relay 5 is kept in the state of opening in order that safety is secured, and thus an electric current is not applied to a first relay 4. In such a case, when the switch 9 is manually turned on, the first relay 4 is actuated, and a contact point 4a therefor is closed, and thus the electric current is applied to a heating element 1, and water-heating can be easily restarted. When a water temperature in a water storage tank rises and reaches a boiling temperature, the overheat- preventing device 3 is actuated, and the contact point therefor is opened and the contact point 4a for the first relay 4 is opened, and thus electricity to the heating element 1 is turned off.

Title: Viscosity measuring device
Inventor: TOMITA TAKESHI
IPC: G01N11/04
Filed: 1983-11-07
Abstract: PURPOSE:To control a flow rate and differential pressure without the smallest strain and to perform a measurement of viscosity on such measurement constitution that a control valve by-pass system can not handle it by increasing or decreasing the flow rate of a flow passage by varying the rotating speed of a pump. CONSTITUTION:When the measurement of a viscometer is 10-1,000 poise and the viscosity of a solution M to be measured is 10-100 poise, a variable speed motor 10 is controlled by a variable speed motor driving means 23 and the solution M to be measured which is supplied under pressure through the feed liquid pump 4 flows through the flow passage 7 at a rate (6,944cm<3>/sec) set by a parameter setter 40. In this case, the differential pressure generated between an upper measurement chamber 1 and a lower measurement chamber 2, i.e. differential pressure depending upon a measured value from a differential pressure tranmitter 15 is in direct proportion to measured viscosity and the differential pressure to 100 poise viscosity is 1kg/cm<3>. The set value of the parameter setter 29 is 1kg/cm<3>, so when the viscosity exceeds 100 poise, the rotation of the electric motor 10 decreases and the fluid flowing through the passage 7 is reduced, so that the differential pressure is held below 1kg/cm<3>.

IPC: G11B15/60
Filed: 1983-11-10
Abstract: PURPOSE:To attain sure recording and reproduction by providing a tape guide means for regulating other end of a tape in broadwise direction to prevent a track shift. CONSTITUTION:A tape guide 15 is made of a thin and long plate member and a bottom part 15a is fixed to a head stand 12 with screws. A couple of standing parts 15b are provided in the vicinity of both ends of the bottom part 15a by clipping a head 13. In recording or reproducing a signal to a track T1 existing eccentrically at an edge 22b of the tape 22, the edge 22a of the tape 22 is regulated by a stopper 15d through the operation of a tapered curved face 15c and pushed up to the height. Since the tape broadwise direction is regulated accurately by the stopper 15d and the head touch is improved while the edge 22b of the tape 22 is kept to a large tension, the recording and reproduction to the track part T1 are performed surely. Furthermore, in conducting recording or reproduction to a track T2 biased to the edge 22a of the tape 22 conversely, the tape guide 15 is placed to the opposite side by 180 deg..

IPC: G01B11/06
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure the film thickness of a thin film regardless of the temporary fluctuation of the intensity of a light emitted from a light source. SOLUTION: A light emitted from a light source part 120 is divided into first light with which a substrate is irradiated and second light with which the substrate is not irradiated. A first light receiving part 130 measures reflected light from the substrate among the first light with which the substrate is irradiated. A second light receiving part 140 measures the second light simultaneously with measurement by the first light receiving part. Then, the film thickness of a thin film is decided from the observed value of the reflectivity of the first light calculated by correcting a first measured value measured by the first light receiving part by a second measured value measured by the second light receiving part, and the predicted value of the reflectivity predicted from the plural film thickness values of the thin film.
