Title: Low iron loss directional magnetic steel sheet
Inventor: ARAI SATOSHI
IPC: C22C38/00
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce the iron loss without lowering the magnetic flux density large by forming linear or discontinuous linear grooves not only in steel sheets on one side but also in steel sheet surfaces on the opposite side. SOLUTION: Linear or discontinuous linear grooves are formed not only in steel sheet surfaces on one side but also in steel sheet surfaces on the opposite side. As against the positions X1 , X2 of adjoining linear grooves on steel sheet surfaces on one side especially, it is desirable that linear grooves should be formed at a position Y of the steel sheet surfaces on the opposite side (however, X1 +(X2 -X1 )/5<=Y<=X1 -(X2 -X1 )/5, but (X1 <X2 )). Here, the position of a groove is that of the center line of the groove. As a groove manufacturing method, methods by the use of a gear roll, by pressing linear projecting teeth, by the use of photoetching, by electric discharge machining, etc., are given, but are not restricted specially.  By forming specific grooves, in this way, it becomes possible to realize material of an extremely low iron loss and a high magnetic flux density B8 (a magnetic flux density at an exciting force 800A/m).

Title: Delay time control circuit
Inventor: OKAMURA YUKIMICHI
IPC: H03K5/131
Filed: 1987-04-01
Abstract: PURPOSE:To attain delay time control with excellent high accuracy and high speed by supplying the current of a constant current source and the discharge current of a capacitor when capacitor discharges through other transistor (TR), and utilizing the switching of the TR to stop discharging. CONSTITUTION:When an input terminal 21 goes to a high level and an input terminal 22 goes to a low level, TRs Q2, Q3 are turned off and the current from a constant current source 13 charges a capacitor (C) 16 through a diode (D) 15 and a comparator voltage 23 is generated. When the voltage 23 is coincident with a reference voltage 17 deciding the delay time, the output of the comparator 11 is inverted. Then the input pulse signal is inverted and the C16 discharges an electric charge through the TR Q3 and the current from a constant current source 13 flows through the TR Q2. Moreover, when the potential of the C16 is decreased to a reference voltage 18 deciding the base potential, the TR Q5 is turned on and the TR Q3 is turned off to stop discharging the C16. Thus, the delay signal 25 with less temperature dependency, high accuracy and high speed is outputted.

Title: Ionizing method and device for high pressure mass analysis
Inventor: FUJII TOSHIHIRO
IPC: H01J49/10
Filed: 1988-04-02
Abstract: PURPOSE:To ionize a specimen effectively under atmospheric pressure by arranging a primary ion generating body incl. alkali metal salt in an ionizing chamber, and heating the ion generating body. CONSTITUTION:When power is supplied to a heater wire, a primary ion generating body 10 fixed thereon is heated, and lithium ions Li<+> are dissociated from its surface. At this time, electrons remain within the ion generating body 10. Thus inside an ionizing chamber 6 is put in the condition with rich lithium ions, and when a specimen is introduced together with the carrier gas into this ionizing chamber 5, the lithium ions are attached to this specimen. These additional ions are accelerated to become an ion beam and led to a sensor part 4 from an ion source slit through analyzing place 3. This allows effective ionization of the specimen under the atmospheric pressure, and ionization of different types of organic substances becomes practicable.

Abstract: PURPOSE:To enable viscous material to be stably supplied in the form of film to the side of a shaft part by providing a rotating disk opposed to a nozzle for discharging the viscous material in a device for applying the viscous material like grease. CONSTITUTION:Grease supplied through a supply hose 12 is sent to a grease nozzle 13 which in turn supplies the grease to both surfaces of a disk 14.

An averaging circuit 2 averages the signals S10 for a single field period and transmits them synchronously with a vertical fly-back line. A filter LPF3 has characteristics for deleting the flicker component out of the output signal of the circuit 2 and obtains a signal by deleting the flicker component out of a signal S11. A delay circuit 4 functions to secure the coincidence in phase between the signals S10 and S11 and delays the signal S10 by three field. A gain control circuit 6 performs multiplication between the signal S10 and the output signal S14 of a division circuit 5 for deletion of the flicker component. Thus it is possible to attain the effect equivalent to the conventional ones with simple constitution containing just a single LPF.
