Title: Circuit board connection structure body
Inventor: HARADA YOSHIHARU
IPC: H01R12/04
Filed: 1995-05-17
Abstract: PURPOSE: To provide a circuit board connection structure body in which contact resistance can be made sufficiently low by sufficient contact pressure. CONSTITUTION: Since plate springs 36, 38 are provided outside a closed space 34 and wall parts 40, 42 are made thin and become easy to warp by nipping pressure, energizing force is given to a case 6 in its part, thereby simultaneously generating contact pressure between contact parts 24, 26 inside the closed space 34 and terminals 12, 14. For that reason, a material and a shape in which only energizing force is taken into consideration independently of the nature as a terminal can be adopted for the plate springs 36, 38 and optimal material and shape can be used for the plate springs 36, 38. A material which is preferable for an energizing member, for instance, phosphor bronze, beryllium copper or the like can be used.  Since the contact parts 24, 26 contacted to each other and the terminals 12, 14 are independent of the nature of a spring material, a material and a shape which are suitable for a terminal can be adopted. Therefore, a sufficiently low contact resistance can be obtained by sufficient contact pressure.

Filed: 1993-05-20
Abstract: PURPOSE:To attain excellent data communication by detecting the presence/ absence of a predetermined tone to a trunk and controlling an amplifier function and a bypass prevention circuit based on the result of detection and to send information of a modem signal without any change. CONSTITUTION:In the case of a modem executing amplitude modulation in terminal equipments 10, 11, when the terminal equipment 11 replies, an answer tone from the terminal equipment 11 reaches an office line trunk 1 through a public nutwork 9. An answer tone detection circuit (DET) 5 of the trunk 1 detects and informs a control circuit (CPU) 6 of it. The controller 6 gives a command of stopping a function to a speech signal amplifier 2 and a bypass signal prevention device 3 through this notice. That is, the amplifier 2 amplifies a communication signal based on the result of detection of the answer tone by the answer tone detection circuit 5. Since amplitude information and signal information in a modem signal are sent between the terminal equipments 10, 11 without any change, excellent data communication is attained.

Title: Interpolating method for luminance of picture element
Inventor: MYODO SHIGERU
IPC: H04N19/132
Filed: 1988-05-17
Abstract: PURPOSE:To reproduce and display a clear picture having a smooth contour by deciding the luminance of a picture element to be interpolated and not held between the sample picture elements in the row or column direction after increasing the correlative value between a pair of sample picture elements set in the oblique direction in the smaller absolute value of luminance difference between said two sample picture elements and interpolating the luminance of one of the paired sample picture elements having the smaller absolute value at first. CONSTITUTION:The luminance of a picture element 222 to be interpolated is defined as the average luminance value of two sample picture elements set in one of the two oblique directions that has the larger correlative value. In other words, I12 and I21 are decided as I12=(Ia+Ic)/2 and I21=(Ia+Ib)/2 respectively when I12, I21 and I22 show the luminance values of picture elements 212, 221 and 222 to be interpolated respectively. Then DELTAad=¦Ia-Id¦ and DELTAbc=¦Ib-Ic¦ are calculated when the correlative direction is decided. Then the correlative value is increased in the direction of the smaller one of DELTAad and DELTAbc and the luminance I22 is decided from the sample picture element set in said direction. Thus it is possible to reproduce and display a clear picture having a smooth contour.

Title: Rotary head drum device
Inventor: TADERA TAKAMITSU
IPC: G11B5/02
Filed: 1995-05-18
Abstract: PURPOSE: To make a rotary head drum device have a simple structure by arranging a rotary transformer and a drum rotor in such a manner that only the stator of the transformer penetrates the inside of the drum rotor and that the rotor and stator of the rotary transform face each other in the upper part of the rotor of the drum motor. CONSTITUTION: A magnetic field is generated in the coil of the stator 52, and the rotor 51 and the drum 10 rotate when the drum motor 50 is energized. A magnetic head 60 outputs reproduced signals when the tracks on a magnetic tape (not shown in Fig.) are scanned. The output signals from the magnetic head 60 are outputted from the rotary transformer rotor 41 to the rotary transformer stator 42 and to a head amplifier (not shown in Fig.) outside the drum device. At this time, the rotary transformer stator 42 passes the central part of the drum motor 50 and, therefore, the signal line receives the noises from the driving signal of the drum motor 50. The signal line, however, passes nearly the center of the drum motor 50 and, therefore, the influence of the noises is low.  Since a shielding plate 80 is formed on the outer peripheral surface of the rotary transformer stator 42, the influence is further suppressed.

Filed: 1977-10-07
Abstract: PURPOSE: To employ the functon of simple dish washing and drying and greatly increase the efficiancy of handling by placing to a washing tub a store-compartment for washed dishes with an air-inducing part.  
     CONSTITUTION: A cylindrical body 1 composes a washing tub2.

Next, when a dish 12 to  be washed is neared with a hand to the upper part of the guide column 6, the pressure of up-stream washing water 7 increases and suddenly turns its direction in its pressurized state. This directon turning takes place as the washing water 7 strongly presses against the dish surface 12 hydraulically, finishing the dish washing several times faster than by hand. Also air stream, being heated, comes out from an opening 17 and opening 15. Therefore, a great amount of heated air passes, heating the  water layer on the dish surface 12

Abstract: PURPOSE:To achieve safe and accurate transportation of blood to a magnetic fluid added to fill the inner cylinder by a method wherein an outer cylinder and an inner cylinder are arranged to be penetrated into a blood passage path and a torque is applied non-contact to the outer cylinder by a magnetic field application means from outside. CONSTITUTION:A rotary impeller 2 is set in a place selected properly of an artificial blood vessel 1 free to rotate with an outer ring 3 and an inner cylinder 4 has a magnetic fluid 7 added to fill respective recesses 6 formed on the outer circumference thereof and is kept in surface contact with the internal surface of the outer ring 3. An electrostatic magnetic field pole 8 is provided coaxially in the perimeter of a setting position of the impeller 2 and when power is fed to control or drive from a magnetic field application power source 9, a rotary magnetic field is generated in the perimeter of the rotary impeller 2 to attract the magnetic fluid 7 to a magnetic pole side sequentially so that a torque is applied to the rotary impeller 2 circumferentially. Thus, as the rotary impeller 2 rotates under lubrication of the magnetic fluid 7 and a propelling wing 5 is driven to rotate, blood passes forcibly from the upstream to downstream side of the artificial blood vessel 1 thereby achieving safe and accurate transferring of the blood in a non-pollution manner.
