Abstract: PURPOSE:To provide the developing device suitable for solving the difficulty in imparting a uniform and good electrostatic charge to a nonmagnetic one- component developer. CONSTITUTION:This developing device develops an electrostatic latent image by bringing a latent image holding member 10 having the electrostatic latent image in contact or proximity with or to a developer carrying member 20 formed with a thin layer of the nonmagnetic one-component toner on the surface by a thin layer forming member. The surface of this developer carrying member 20 consists of a layer contg. the aminosilane coupling agent expressed by general formula in a silicone polymer or ethylene/propylene/diene/methylene polymer. (In the formula, R<1> is an alkyl group; R<2>, R<3> are a hydrogen atom or alkyl group; either or both of R<2>, R<3> are alkyl groups). The sufficient electrostatic charge quantity and adhesion quantity are obtd. by the toner if the silica is incorporated into the surface layer of the developer carrying member of this developing device.

Title: Semiconductor device
Inventor: MIYAJIMA TATSUO
IPC: H01L29/08
Filed: 1979-02-26
Abstract: PURPOSE:To shorten turn-off time and reduce a loss in a turn-on state even in high- frequency operation, by producing a short-circuit emitter continuous in the direction of the edge of an emitter layer. CONSTITUTION:p-Layers 12, 13 are provided on an n-type Si substrate 11. An n- type main emitter 14 and the emitter 15 of an auxiliary SCR are produced on the layer 13 and gold is diffused to shorten turn-off time. The layer 14 is shaped as continuous parallel comb teeth so that its width A is about 0.5mm. The layer 14 is conjoined to an Mo plate 16 by an Al brazing material 17. A main emitter electrode 18, a gate electrode 20 and an electrode 19 for the auxiliary SCR are then produced. A short-circuit emitter 21 is thus provided along the longitudinal edge of the main emitter layer 14. In high-frequency operation, a turn-on region extends by only 0.5mm or less from the edge of the layer 14 and enough turn-on action is performed. Since the short-circuit emitter is not located in the emitter layer 14 under the main emitter electrode 18, the extension of the turn-on region is not hindered. This results in providing a device of short turn-off time and little power loss in its turn-on state.

Title: Cutter
Inventor: HANDA KATSUMI
IPC: B23K10/00
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To improve cutting quality and to prevent the failure of a compressor by connecting a pressure limiter and a pressure regulator to a compressed air route between the compressor and a cutting torch. SOLUTION: The set pressure of the pressure limiter 10 is set around the lower side of the compressed air large in the fluctuation between the upper and lower pressures supplied from the compressor 2, by which the compressed air past the pressure limiter 10 is made into the stable compressed air free of the pressure fluctuation. If the work 7 is worked with the cutting torch 5 by the compressed air converted to the adequate pressure of the cutting work by the pressure regulator 4, the compressed air pressure is stable and, therefore, the cutting width is made constant as well and the cut surface of the work 7 is made smooth. The cutting quality is thus improved.  The compressed air pressure on the discharge side of the compressor 2 is kept at the pressure set by the pressure limiter 10 at all times by the pressure limiter 10 and, therefore, the overloaded operation of the compressor 2 is averted and the failure of the compressor 2 is prevented.

Abstract: PURPOSE:To obtain an adsorbent well adsorbing both of a basic and acidic malodorous compounds by rapidly freezing hydrated swollen montmorillonite mineral and subsequently freeze-drying the frozen one under pressure. CONSTITUTION:When a tank is filled with water and powdery montmorillonite mineral is gradually charged in the tank little by little under stirring, the montmorillonite mineral is uniformly dispersed to become a uniformly hydrated and swollen liquid state. When this hydrated and swollen composition is brought into contact with a low temp. medium such as an ethanol/dry ice mixture, the composition is instantaneously frozen to float and a frozen substance is obtained. Further, this frozen substance is charged in a vacuum freeze-drying apparatus while the frozen state thereof is kept in an atmosphere of 0 deg.C or less to be freeze-dried under vacuum. The adsorbent thus obtained develops good deodorizing properties to both acidic and basic malodorous compounds.

Title: Video detection device
Inventor: ISOBE MITSUO
IPC: H04N5/455
Filed: 1984-02-10
Abstract: PURPOSE:To discriminate a white directional standard of a video signal by making detection phases different at the first signal arrival period and the second signal arrival period which is the other period, except a synchronizing signal pulse arrival period within a horizontal flyback period, in detecting amplitude modulated television signal. CONSTITUTION:When assuming a phase transition amount as DELTAtheta for a luminance signal level x% and assuming an amplitude VY between video signal reference black level and maximum white peak signals as 100 in a standard television system, a synchronizing signal pulse amplitude VS is specified as 40, thus representing by an equation I , where said amplitude VS is specified as 87.8% at the maximum modulation factor of m=video signal. Therefore it can be simplified as an equation II. For example, if said transition DELTAtheta is zero, x=0 can be obtained from theta=180 deg.. When assuming that a phase shifter 6 gives a phase transition of DELTAtheta=90 deg., x=120% can be obtained from the equation II, and an output level of a multiplier 2 with respect to the first signal arrival period is increased with respect to the luminance level 0% in the case of the output level being DELTAtheta=zero, thereby transmitting signals which exceed 100% white peak levels.

Title: Log-out system for fault information of multi-processor system
Inventor: UCHIBORI IKUO
IPC: G06F15/177
Filed: 1987-02-05
Abstract: PURPOSE:To improve the performance of the titled log-out system by performing a log-out action for the hardware information only as necessary in case an exceptional interruption occurs during the execution of a program. CONSTITUTION:A writable memory means 50 is set into a system control part 40 provided between a main memory 30 and a system bus 10. When the control information is registered into the means 50, the means 50 works to form a mask to decide whether an exceptional log-out action should be carried out or not in response to each bit. As a result, the control parts 2101-210n of processing units 2001-200n transfer the contents of the log-out information parts 2201-220n to the log-out areas 3001-300n of the main memory 30 respectively if the corresponding bit of said mask is set when an exceptional interruption is produced. While the contents of the parts 2201-220n are not transferred if the corresponding bit of the mask is reset. Thus the system maintenance properties can be improved.
