Title: Forming method of soft magnetic film
Inventor: KATO YOSHIFUMI
IPC: H01F10/14
Filed: 1991-08-13
Abstract: PURPOSE:To obtain a soft magnetic film which is high in reliability of adhesive strength and excellent in soft magnetic characteristics. CONSTITUTION:A boron-containing soft magnetic film is formed through electroless plating using borane as reducing agent. Baron is comparatively small in atomic weight, so that an atomic weight difference between baron and other metal atoms which constitute the soft magnetic film is large. Therefore, blocks composed of boron and other metals become large in distortion, so that blocks hardly collect, in result the soft magnetic film concerned becomes small in crystal grain. Therefore, magnetic domain walls grow high in mobility in a soft magnetic film of this design, so that the film displays its excellent soft magnetic characteristics.

Title: Cd-rom and method for finding copy of cd-rom
Inventor: TSUCHIYA MASAYOSHI
IPC: G06F21/12
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To purge a pirate CD-ROM by embedding a key word in an area of CD-ROM where it is difficult to read out the key word. SOLUTION: An unused subcode area, where it is difficult to read out a data, is selected among data areas storable on a CD-ROM. A specific key word is embedded in that area. The CD-ROM is provided with a corresponding function for reading out a data from the area embedded with the key word. A routine for deciding whether a CD-ROM is a regular product or not and imposing a penalty to an irregular CD-ROM is built in the program of CD-ROM. Pirate products are purged using these functions thus protecting a regular product.

Title: Constant vehicle sped braking device
Inventor: ISHIHARA KIMIO
IPC: F02D9/02
Filed: 1985-09-13
Abstract: PURPOSE:To sustain vehicle speed at a set vehicle speed, by feeding pressure fluid into a pressure chamber for effecting brake action when a signal from a vehicle speed sensor exceeds the set speed. CONSTITUTION:A pressure chamber 39 defined by an auxiliary piston 35 in a valve body 6 advances the auxiliary piston 35 and a valve plunger 11 by means of fluid pressure introduced thereinto to change over passages for a valve mechanism 7. The supply and discharge of fluid pressure to and from this pressure chamber 39 is controlled by a liquid passage change-over mechanism 44. Further, when a signal from a vehicle speed sensor 55 exceeds a vehicle speed set on a vehicle speed setting unit 54, a control device 53 controls a fluid change-over mechanism 44 to feed pressure fluid into the pressure chamber 39 for effecting braking action. Accordingly, even if accelerator is released on a steep slope, it is possible to sustain vehicle speed at the set vehicle speed by applying brake action.

Abstract: PURPOSE:To contrive to manufacture a small semiconductor substrate by combining the specific inner nodes with pads installed at measurable positions with a non-contact type test apparatus. CONSTITUTION:Memory with a logical function includes a plurality of controlling flip flop circuits EF1 and a plurality of scan out pads SP1 formed at the measurable positions with an EB tester etc. and combined with the holding nodes of the corresponding controlling flip flop circuits EF1. When the memory with a logical function is set into the specific test mode, the specific test data are supplied from a test logical unit to the specific outer terminal of the memory with a logical function. The specific electronic beam EB is applied from the EB tester combined with the test logical unit to the scan out pads SP1. Secondary electrons emitted from the scan out pads SP1 by applying the electron beam EB are taken in the sensor ES of the EB tester. The test logical unit judges the potential of the corresponding holding nodes according to the size of the output signal of the sensor ES of the EB tester and compares and collates the results of the judgement with the expected value data provided beforehand. This enables manufacturing small memory with a logical function and reducing the costs.

Title: Method and device for editing composite video signal
Inventor: SHIRAKAWA RYUJI
IPC: G11B27/02
Filed: 1992-07-07
Abstract: PURPOSE:To make accurate edition possible by synchronizing a composite video signal reproducing means with a reference color frame before phase adjustment and supplying a composite video signal obtained by reconversion to a composite video signal recording means. CONSTITUTION:An edition start point is inputted by operating an editor CT 3, and prior to the execution of dubbing, a master VTR l and a slave VTR 2 are prerolled. The VTR 2 receives a color frame signal CF based upon a command signal 3a supplied from the editor CT 3 and synchronizes the travelling of a magnetic tape with the signal CF. The phase of the VTR l is adjusted to that of the VTR 2. When the traveling speeds of both the VTRs 1, 2 coincide with each other after ending the phase adjustment, the edition start points of both the VTRs 1, 2 are made coincident and the edition start point of a reproduced composite video signal 1a is made coincident. Similarly the color frame of a composite video signal 4a to be an output signal from a component conversion means 4 is also made coincident.

Title: Segment shape
Inventor: NISHIOKA IWAO
IPC: E21D11/08
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To reduce cost and ensure the safety by dividing a self-weight of a segment and work external force into minute forces and overlapping a cross sectional force generated by step analysis in which respective divided forces act sequentially. SOLUTION: For example, a cross sectional force at a joint position generated when arbitrary load obtained by dividing an action load acts is expressed by an axial force, a bending moment, and a shearing force. In this case, an incremental cross sectional force is calculated using a spring value of a joint corresponding to each position and each cross sectional force from the generated cross sectional force, and a cross sectional force by all action loads is calculated by repeating the procedures for calculation. A form is designed, and concrete is placed in the form to manufacture a segment in this way. Consequently, a rotation spring value and a shearing spring value used in analysis are used as values corresponding to respective position and cross sectional force to obtain the economical segment.

Title: Image forming device
Inventor: YOSHIDA MINORU
IPC: G03G15/08
Filed: 1990-07-31
Abstract: PURPOSE:To surely prevent toner from being accumulated in a toner image nonpatterning means and to prolong the life of the device by providing a mode wherein the toner accumulated in the transfer remaining nonpatterning member is discharged to an image carrier and applying an AC bias to the toner image nonpatterning means. CONSTITUTION:A toner image and an electrostatic latent image slightly remain on the surface of a photosensitive drum 1 after transfer and are carried to the transfer remaining toner nonpatterning means 2. A DC bias having the opposite polarity from the toner is applied to a brush 2a so as to attract the transfer remaining toner temporarily and inject charges. Much of toner attracted temporarily to the brush 2a resticks on a drum 1, but the rest of the toner can not restick and is accumulated in the brush 2a gradually. Consequently, discharging operation (discharge mode) for the toner accumulated in the brush 2a is performed during print start operation and/or end operation, etc. In this discharge mode, a DC bias is applied and then even toner entering the brush 2a deeply is discharged to reduce the accumulation in the brush 2a, thereby prolonging the life of the device.

IPC: B65H29/26
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To stack and store sheet workpieces fed horizontally downstream from one process step in a preselected storage box without damaging them or causing imperfect storage. SOLUTION: When a sheet workpiece is carried by a feed conveyor part 2 from an upstream process step down to a clamping feed part where it is stopped, an upper clamp 13 and a lower clamp 15 hold the leading end of the sheet workpiece. The clamping feed part is then moved in the workpiece feed direction, and at the same time an auxiliary roller part 21 is moved also in the workpiece feed direction at a lower rate than the clamping feed part to support the undersurface of the sheet workpiece forwarded. When the trailing end of the sheet workpiece leaves a sensor 4, the auxiliary roller part 21 is returned to its workpiece waiting position and at the same time the lower clamp 15 is turned downward to thereby let the sheet workpiece fall into a storage box 23 where it is stored.
