Title: Molded coil hardening method and device thereof
Inventor: KURACHI YOSHIKAZU
IPC: B29C45/78
Filed: 1990-10-17
Abstract: PURPOSE:To reduce residual stress, and to improve the quality of a molded coil by a method wherein the heating of resin is controlled in such a manner that the highest temperature of the resin, based on the detected value of the interterminal voltage of the coil, the current and the temperature of a mold, does not exceed the preset temperature. CONSTITUTION:Resin 3 is poured into a mold 1, a current is allowed to flow to a coil 2, and after heating is started, the resistance value R of the coil 2 is computed based on the interterminal voltage and then the current value of the coil 2 is computed every 1 to 5 minutes, and the temperature (ta) of the coil 2 is computed using the temperature conversion formula suited to the above-mentioned resistance value and the material of the coil 2. At the same time, the highest temperature (tmax) of the resin 3 is judged based on the temperature (ta) of the coil 2 and the highest temperature (t1) of the surface of the resin 3 sent from a temperature detector 13. In this case, the temperature of the coil 2 and the temperature of the resin 3 go up almost equally in the initial stage of heating. The heating output of the coil 2 is controlled by a power controller so that the highest temperature (tmax) of the resin 3 will not exceed the preset temperature, and the stress remaining on the molded coil, for which a hardening treatment is completed, can be decreased.

IPC: F16F15/08
Filed: 1992-09-22
Abstract: PURPOSE:To suppress the resonance phenomenon due to the frequency of a vibration source by setting the spring constant of one rubber bush sufficiently larger than the spring constant of the other rubber bush, as for a vibrationproof rubber consisting of a rubber bush surrounding an inner cylinder and a connecting rod made of synthetic resin. CONSTITUTION:Inner cylinders 1 and 2 are surrounded by rubber bushes 3 and 4, which are installed at both the edges of a connecting rod 5. The rubber bushes 3 and 4 perform a vibration absorbing action in use and a buffering action for a sharp load, and is used for reducing noise. Cut parts 6 and 7 are formed in the extension direction of a connecting rod 5 on the rubber bush 3 side. The cut parts 6 and 7 serve for obtaining a different spring ratio between the rubber bushes 3 and 4, and vary the characteristic frequency of a vibrationproof rubber, and shifts resonance point. Accordingly, the characteristic frequency can be set high without varying the spring constant of a product, and the resonance within the used frequency range of the conventional vibrationproof rubber is prevented, and the vibration suppressing effect can be improved.

Title: Electronic ignition timing control device
Inventor: KATOUGI KOUZOU
IPC: F02P5/152
Filed: 1989-10-27
Abstract: PURPOSE:To prevent the wrong detection of knocking by comparing an actual background level with the minimum value of a background level obtained according to engine speed and load, and maintaining the actual background level over the minimum value at the time of the actual background level being small. CONSTITUTION:Knock signals from knock sensors 1-4 are sent into an analog multiplexer respectively through preamplifiers and further into a gain-changeable amplifier. Because of fetching characteristic frequency elements as the knock signals, this output is inputted into a band-pass filter BPF, and this output is sent into a rectifier circuit so as to fetch the alternating parts of the knock signals as d.c. voltage. This d.c. voltage enters into an integrator, and integration is started at the specified angle or after the lapse of the specified time from the ignition timing and continued for the specified angle or time. The knock integrated value is compared with a background level. At the time of this value exceeding the specified ratio corresponding to engine speed, the generation of knocking is detected, and the background level is compared with the minimum value of a background level obtained from the engine speed and load.

Title: Image encoding method
Inventor: FUJIMURA KOTA
IPC: H04N19/00
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To encode image data with high compressibility by a simple method. SOLUTION: An original image is encoded into one-side outline information showing the outline of one side of each area. The one-side outline information is obtained by scanning the image in one constant direction, detecting one-side outline points forming the outline of one side of the area, and putting position information on one-side outline points and color information on the one-side area of the one-line outline points together into the one-side outline information. Further, one-side outline points which are in the same area and adjacent to each other are connected to generate a one-side outline and information regarding the one-side outline is encoded to make the compressibility higher. The one-side outline information consists of respective pieces of information showing the start positions, shapes, and colors of respective one-side outlines. Further, information on the said start point is encoded with high efficiency by using a binary image consisting of two pieces of information on the start point of the outline and a non-start point other than the start point.

IPC: H05K1/02
Filed: 1991-09-30
Abstract: PURPOSE:To prevent noise leakage from a gap between an insulated metal substrate and a shield case, by installing a case for sealing circuit elements, and a shield case covering surfaces except a surface on which outer leads are formed, and adjacently arranging outer lead terminals for grounding and earth pins of the shield case. CONSTITUTION:A shield case 40 covers all surfaces except a surface on which outer leads 30 of a hybrid integrated circuit device are arranged. Difficulty of press working is considered, and two face materials are individually press- worked in lid type members. After the members are stacked, the overlapped parts are bonded by spot welding, at an interval smaller than or equal to about 1/10 of the wavelength of noise to be generated. Thereby a box is formed. A shield case 40 has a pair of earth pins in each terminal end portion, which are connected with outer leads 30 for grounding the hybrid integrated circuit device, in the state of the shortest distance and low impedance. As the result, in a high frequency region, the potential of the shield case 40 becomes equal to that of the outer leads 30 for grounding, and the noise shielding effect is improve.

The scanning infrared rays 3 are projected on the material to be observed through openings 15 linked in a belt shape and openings 14 linked in a drum shape. The reflected and returned infrared rays 4 are reflected from the outer surface of a holed mirror 5 through the reverse path with respect to the infrared rays 3. The infrared rays 4 are guided to a photodetector 7 through a light receiving lens 6. An opening 16 is limited to the size of an instantaneous field of view with the openings 15 and 14. The openings 15 and 14 are moved in main scanning directions 10 and 9 in synchronism with the optical scanning, respectively. The ratio of the opening 14 is determined at the optimum value with the optical system for optical scanning. The openings 14 are moved by a motor and turned at the speed of twice that of the scanner 21. The number of the openings is one half the number of the surfaces of the polygon mirror.
