IPC: G03G5/04
Filed: 1979-12-12
Abstract: PURPOSE: To allow a receptor to hold superior reproducibility in the visible light region by adding a disazo dye having a specified structure to the photosensitive layer as an effective component.  
     CONSTITUTION: To the photosensitive layer of an electrophotographic receptor is added an about 1W50wt% disazo pigment as an effective component represented by formula I, e.g., the compound of formula II. This compound effectively acts as a charge carrier generating substance with superior sensitivity on the shorter wavelength side in the receptor. This disazo pigment is easily manufactured by diazotizing 3,4'-dinitrodiamino-trans-stilbene followed by isolation as tetrazonium salt and coupling with a corresponding naphthol AS coupler in a suitable org. solvent in the presence of alkali.

Title: Pressure monitoring device
Inventor: MARUTANI TOMOHIRO
IPC: G01L19/12
Filed: 1981-10-06
Abstract: PURPOSE:To obtain the pressure monitoring device whose reliability in fault detection or prediction is higher, by monitoring the pressure (density) value as well as the temporal speed of change in the pressure (density) in a container. CONSTITUTION:When an arcing fault occurs and the internal pressure reaches a preset value PB, a switch SPB is actuated, and its contact signal is sent to a time counter circuit TM2 and to an alarm circuit AL. When the internal pressure is increased and reaches a preset point PC and a switch SPC is operated, a circuit TM2 stops the measurement of the elapse of time and sends a time signal DELTAt2, which represents the measured elapsed time, to a comparing circuit COM2. In the comparing circuit COM<2>, the signal DELTAt2 is compared with a reference value DELTAT2. When DELTAt2<DELTAT2 a locking signal is outputted, a corresponding breaker CB is operated through a trip circuit TR, and a faulty part is instantly isolated. When DELTAt2>DELTAT2, the fault is not serious, and it is judged that enough time is available for the action taken by the service personnel. Therefore only the alarm is indicated by an alarm circuit AL.

Title: Engine shut-down device at oil feeding
Inventor: MOCHIDA HARUO
IPC: B60K15/05
Filed: 1978-12-28
Abstract: PURPOSE: To feed oil safely by shutting down an engine automatically upon detection of a fuel filler lid being opened in an automobile for which the lid can be opened without using an ignition key.  
     CONSTITUTION: When an automobile starts running the an ignition switch on, a running detection swtich 8 is also turned on, and a circuit becomes conducting. Then, where a fuel filler lid 1 is opened by operating an opening device 2 erroneously, a detection swtich 7 is turned off. However, the swtich 8 is kept on as long as the automobile is running, and hence the circuit is kept from being nonconducting, thus preventing an engine from misfire. On the other hand, the switch 8 is turned off by shut-down of the automobile at oil feeding. Therefore, if the lid 1 is opened for oil feeding with the switch 6 on, the switch 7 becomes off to keep the circuit nonconducting, thus shutting down the engine.

IPC: B24B19/02
Filed: 1988-06-29
Abstract: PURPOSE:To make it possible to complete machining in a short time and equalize the channel depth on the sides of a pocket and an oil feeding channel by turning a throttle passage connecting the oil feeding channel and a static pressure pocket around an axis in parallel with the throttle passage and machining with a cylindrical tool having width greater than the throttle passage and with a cutting blade on its outer periphery. CONSTITUTION:First, an oil feeding channel 14 and a static pressure pocket 16 are machined with the end mill of a milling machine. Next, a sliding face 13 is machined with a surface grinder in such a way that its roughness is lessened and smoothened. Furthermore, the cylindrical abrasive wheel 30 of the surface grinder is positioned in parallel with each throttle passage, and the abrasive wheel 30 is moved toward the sliding face 13, then the cross section of the throttle passage 15 is machined in a circular arc. Since the abrasive wheel 30 has, as its cutting blade, abrasive grains on its outer periphery and its width is greater than the throttle passage 15, the thermal expansion of the throttle passage 15 during the machining process becomes the same on the side of the oil feeding channel 14 and that of the static pressure pocket 16, which makes it possible to equalize the depth of the throttle passage 15 and to complete the machining in a short time.
