Inventor: CHIKUMA ISAMU
IPC: F16H55/18
Filed: 1994-02-04

Title: Cancelling device for residual magnetic field in omega type energy analyzer mode
Inventor: NAKANISHI KAZUNARI
IPC: H01J37/252
Filed: 1986-01-23
Abstract: PURPOSE:To make it possible to complete, with only one try, shaft adjustment in transmission type electron microscope (TEM) mode and Omega type energy analyzer (OMEGAEA) mode during observation of an image, in TEM mode, by cancelling a certain amount of residual magnetic field from the magnetism in satutated state, after making an OMEGAEA lens magnetically saturated. CONSTITUTION:When the power switch 20 of an electron microscope is turned on, a relay 30 operates to close a switch 33 so that an electric current is supplied to an extent required for making OMEGAEA lens saturated by means of a power supply V3. A one shot multivibrator 25 is triggered to invert FF 27 at the trailing edge of pulse t1 (timing T1+t1) and the resultant output is supplied to a relay 31 through an inverter 29 to turn a switch 34 on. Since excitation current is cut off and residual magnetic field B1 is at a constant level, supply voltage of a power supply V2 is regulated so that an electric current may be supplied to an extent corresponding to DELTAH required for cancelling the residual magnetic field B1 of OMEGAEA lens through amplifiers 36, 37. Accordingly, it is no more necessary to readjust the shaft at the time of making mutual changeover among respective modes in the case of observing an image in TEM mode.

Filed: 1980-02-04
Abstract: PURPOSE:To prevent the shift of front gap and to keep sufficient reproducing output, by providing a space specifying the lower end of gap constituting surface and a bonding layer linking the space and a winding hole, between the front gap constituting surface of a magnetic core and the winding hole. CONSTITUTION:Filling-in grooves 11, 12 for adhesives are provided on one side of a sendust core block 10 to fill in silver solders 13, 14. The preventing groove 15 silver solder diffusion for and winding groove 16 are provided. The groove 15 specifies the lower end of a front gap constituting surface 17 with a groove ridge 15a. The depth of the groove 16 is made to the depth >=3 times the groove 11. Further, after polishing the process surface of the block 10 and providing the spacer such as SiO2 on the front gap constituting surface 17 and the back gap constituting surface 19, another core semisphere block is molten and bonded to form the magnetic tape slide surface. Thus, the forming of the diffusion layer 20 on the surface 12 at bonding the adhesives layer 18 is prevented at the groove 15. Thus, without giving effect on the magnetic characteristics, strong bonding is made with no front gap shifted. Then, sufficient number of coil windings can be assured to the groove 16 to avoid the output from being lowered.

Title: Solder assemblage
Inventor: MIZUTANI IWAO
IPC: H05K3/34
Filed: 1985-01-28
Abstract: PURPOSE:To stabilize the supply of solder by attaching plural pieces of molded solder to a sheet material. CONSTITUTION:Large holes 11 are bored at equal intervals to a flexible and long-sized plastic tape 10..The molded solder 12 is attached like caulking to each hole 11. The tape 10 is continuously fed in the longitudinal direction with the aid of small holes 13 disposed at equal intervals to the tape 10, then the continuous feeding of many pieces of the molded solder 12 on the tape is made possible as far as the tape 10 continues. Since the solder 12 is attached into the large hole 11 of the tape 10 in the caulked state, the pull-off of the solder in the mid-way is obviated. The tape 10 is used in the rolled state and therefore the smaller space is required for containing the solder 12 and the contact and sticking of the solder to each other are entirely eliminated. The solder 12 is exactly and stably supplied by the above-mentioned method.

Title: Ultrasonic-wave measuring system
Inventor: NISHIZUKA KEN
IPC: G01N29/22
Filed: 1991-01-09
Abstract: PURPOSE:To provide an ultrasonic-wave measuring system which can increase and decrease the number of channels readily and can control an ultrasonic-wave measuring unit for each channel. CONSTITUTION:Each ultrasonic-wave measuring unit is constituted so that the ultrasonic-wave measuring operation can be performed independently. When a plurality of units are used, one unit among them is specified as a master, and the other units are specified as slaves. The units are connected with a bus one another. The device address specified with the ultrasonic-wave measuring unit on the master side is received with the ultrasonic-wave measuring unit on the slave side through the bus. The address is compared with a device address set in own unit. When the addresses agree as a result, a synchronizing signal is generated. Therefore, the synchronizing signal is made to be the external synchronizing signal. The signal is made to be the timing signal for driving the pulser of the ultrasonic-wave flaw detecting part 1 of each measuring unit. Thus, the measuring timing of a plurality of the measuring units on the slave side can be controlled only by sending the device address on the bus from the master side under the control of the master measuring unit.

Abstract: PROBLEM TO BE SOLVED: To provide a reproducing method, which utilizes the change of impedance due to an external magnetic field to reproduce magnetized information on a magnetic record medium, and a production method of a magnetic head for this reproducing. SOLUTION: In this reproducing method, a DC-biased high frequency carrier current is caused to flow from electrode terminals 5 and 6 to a conductor line 3 existing between an upper core 1 and a lower core 2 having a magnetic gap 7, and the fact that the impedance of the conductor line 3 is changed in accordance with the intensity of external magnetization 8 by the change of permeability of upper and lower cores is utilized to take out the change of external magnetization as the change of an output voltage. Since this head has a simple structure, its production process is simple, and a relatively high yield is easily secured, and it is superior in mass productivity. Reproducing with sensitivity higher than conventional one is made possible because of reproducing based on the change of impedance due to magnetism, and the recording density is made much higher.

Abstract: PROBLEM TO BE SOLVED: To shorten the measuring time and make a subject measurable even when its surface has texture property by calculating the relative magnification between a reference image and a search image from the map radius of the search image where the evaluation function is maximum. SOLUTION: An A/D converter 4 and a computer 5 are mounted on a CCD camera 2, and the image signal from the camera 2 is arithmetically processed to find the distance from a lens to a subject 6. Namely, of two image signals obtained by taking images while moving the camera 2 in the optical axial direction, the image signal having the shorter distance between the lens and the subject 6 is taken as a reference image signal, and the other as a search image signal. The map radius is set so as to include a subject part to be measured followed by coordinate conversion, and the map radius of the search image is then minimized while calculating the evaluation function to find the map radius of the search image where the evaluation function is maximum. The relative magnification between the reference image and the search image is calculated from this map radius, whereby the distance to the subject 6 is found by a lens formula.
