IPC: F16B41/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To perform recycle by removing the parts and the members of various apparatuses without breakage. SOLUTION: A resin member 1 being the outer frame of an industrial product 10 and an internal mechanism thereof are fixed in the bottom position of a product by means of a screw 2.

Title: Ultrasonic probe
Inventor: TSUCHIDA KAZUTOSHI
IPC: A61B8/00
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To solve a problem in a mechanical sector scan type ultrasonic probe that an ultrasonic tomogram is deteriorated by multiple reflections within an opening film provided on the front surface of an oscillator. SOLUTION: A sawtoothed indentation 28 is formed on one side of the opening film 20. The sawtoothed indentation 28 is so formed that its inclined faces 30 get higher from the center to the outer periphery of the opening film 20. Transmission and reception of ultrasonic waves between the oscillator 22 and a subject are effected along the central axis of the oscillator 22, the central axis being perpendicular to the opening film 20. With the indentation 28 provided, the ultrasonic wave impinging on the inclined faces 30 along the axis of transmission and reception of the ultrasonic wave and reflected within the opening film 20 is diagonal with respect to the opening film 20.  Thus, the multiple reflected waves within the opening film 20 move away from the axis of transmission and reception of the ultrasonic waves toward the outer periphery of the opening film 20 each time the reflection is repeated, whereby the multiple reflected waves received by the oscillator 22 are suppressed.

Title: Automobile window regulator
Inventor: KOUNO TOSHIYUKI
IPC: E05F11/38
Filed: 1989-12-14
Abstract: PURPOSE:To automatically close a window glass and open it with an extremely light operating force by setting the restoring force of a fixed load spring larger than the addition of the weight of the window glass and the sliding resistance of the window glass. CONSTITUTION:The restoring force is set larger than the addition of the weight of a window glass 3 and the sliding resistance of the window glass 3. A fixed load spring 4 formed of a drum 5 and a stainless steel leaf spring 6 wound on the drum 5 is fixed to a support body 7 through arms 8, 8. When a lever 21 is operated to lower the window glass 3, the stretching force of a wire cable 17 is made to a light force slightly larger than a value in which the addition of the weight and sliding resistance of the window glass 3 is subtracted from the output of the spring 4. Further, when the window glass 3 is raised, this operation is automatically conducted by the raising force present in the opened state without adding any manual raising force.

IPC: B23P15/28
Filed: 1992-11-12
Abstract: PURPOSE:To enhance the adhesion of a wear resistant protective film by using Al, C, O and N as principal constituent elements.

Filed: 1990-11-27
Abstract: PURPOSE:To enable exact and speedy correspondence by installing a data transmitting means at a branch office or the like and setting or changing the registration of required data corresponding to a request from the place installing a home telephone by a special staff. CONSTITUTION:When it is demanded from a setting destination to change use contents, the staff of the brach office transmits a PB signal to the installing destination and when the signal is received by a telecon unit 4, a CPU 4b makes a response and moves to a change mode. Next, the command signal of the system change is transmitted from a terminal equipment 10b, the data is successively changed and transmitted to a PB line 2 while reading the data of the installing destination. When the data is received by the unit 4, the CPU 4b transmits them to a CPU 5b of a control panel 5, and the CPU 5b reads the data of a RAM 5a and successively changes them. Thus, since the special staff sets or changes the data of the home telephone, exact and speedy correspondence is enabled.

Title: Frequency area image processor
Inventor: MORINAKA YOSHIHARU
IPC: H03H17/02
Filed: 1993-12-24
Abstract: PURPOSE:To easily generate an image, from which an arbitrary frequency component is removed, by designating an arbitrary starting distance, ending distance, starting angle, ending angle or the coordinates of a pair of apexes on diagonals when designating a specified area in a power spectrum. CONSTITUTION:The power spectrum is generated from data on a Fourier transformed data memory 16 by a power spectrum generating part 18 and further, the power spectrum is displayed by a power spectrum display monitor 20. Then, any arbitrary area in the power spectrum is designated by the distance and the angle in that display state. Next, the designated area is displayed on the monitor 20 by a designated area plotting means 24 while being overlapped with the power spectrum. Afterwards, the Fourier transformed data on the memory 16 corresponding to the designated area are changed into zero, for example, and invalidated by a data invalidating means 26. Since the Fourier transformed data on this memory are inversely Fourier transformed by an inverse Fourier transforming part 28, the image from which the correspondent frequency is removed can be easily generated inside or outside the designated area.

Title: Emergency lamp lightup device
Inventor: HAMAHATA SEIJI
IPC: H05B37/00
Filed: 1988-12-23
Abstract: PURPOSE:To prevent ill influence upon the lifetime of a mechanical contact by changing over an emergency lighting control switch from On to Off when the AC mains are recovered, changing over a lamp changeover switch from an emergency inverter circuit to a commercial inverter circuit, and then changing over a commercial lighting control switch from Off to On. CONSTITUTION:When power failure on AC mains is recovered, an emergency lighting control switch S3 is changed over from On to Off, and current supply from the emergency power supply to an emergency inverter circuit IN2 is stopped to cause stopping of its oscillation, and the emergency lighting of lamp is finished. After a certain while, a lamp changeover switch S2 is changed over from the emergency inverter circuit IN2 side to the commercial inverter circuit IN1. At this time, the oscillating motion of the inverter circuit IN2 is stopped already, and current supply to the commercial inverter circuit IN1 has not yet begun, and this remains out of oscillation. Therefore no contact arc will be generated even though changing-over of a chattering switch S2 has caused chattering at the time of changing-over of the lamp changeover switch S2.
