Title: Method and apparatus for cutting and separating electronic element
Inventor: YAMADA YOSHIAKI
IPC: H01L21/78
Filed: 1989-03-24
Abstract: PURPOSE:To reduce the pellet rising phenomenon during the incorporating period of an electronic element and improve the yield by slanting in parallel two faced cut surfaces so as to form a parallelogram, and providing slants toward an electrode surface on the two cut surfaces so that the two cut surfaces become at least a trapezoid or reversed trapezoid. CONSTITUTION:All (e2, f2, g2, and h2) of four cut surfaces of a chip are cut in parallel to have the same slant angle theta, and all of the four cut surfaces are made into a parallelogram. Since the slants are provided on the cut surfaces, in the case where the cut surfaces drop in a sealed glass material in an up-and- down state of the cut surfaces, a reverse moment proportional to the side length and slant angle actuates thereto, and thus, an electronic element is reversed at 90 deg., and stands in an up-and-down state of the electrode surfaces. Whereby the pellet rising phenomenon is reduced, and the yield can be improved.

Title: Outer frame for rotary electric machine
Inventor: TESHIROGI KOUICHI
IPC: H02K5/04
Filed: 1981-05-13
Abstract: PURPOSE:To prevent the deterioration of a product image caused by the difference of the roughness on the surface by coating the steel plate part of the  outer frame which is associated with a steel plate part and a cast part of different surface roughness, with paint similarly to the surface of the cast part  surface. CONSTITUTION:The surface of an outer frame which is made of a material remarkably different in surface roughness is coated by spraying in a pattern which is produced in particular state on the coated surface by suitably adjusting in an electrostatic coating or manual spraying paint viscosity, gun air pressure and bore of the gun. Thus, the smooth surface of a steel plate housing becomes finely particular surface, i.e., rough surface similar to the cast surface, while the surface of a cast end bracket is slightly smoothened with the paint filled in the recesses, thereby equalizing the surface roughnesses of both the surfaces. Then, they are coated by an ordinary finish paint. In this manner, the deterioration of the product image can be prevented.

Title: Vibration damping device of rotary compressor
Inventor: KOYAMA TAKASHI
IPC: F04C29/00
Filed: 1989-03-23
Abstract: PURPOSE:To obtain a sufficient vibration damping effect even if the rotating frequency is changed by fixing one of hooks on the vertical plane to the central axis of the both end parts to a sealed case having a compressing element part and an electric motor part contained therein, and the other to an inertial body. CONSTITUTION:A sealed case 2 is vibrated by the operation of a compressor. The vibration of the sealed case 2 is damped by vibrating the inertial body 15 of a dynamic vibration reducer 14 in the opposite phase to the vibration of the sealed case 2. When a connecting part 16 is formed into a closely adhered coil form and the deformation is used as bending direction, a space is formed between windings to change bending rigidity, whereby damping effect is obtained and the peak width of the natural frequency of the dynamic vibration reducer 14 is widened. Thus, the peak width of the maximum damping frequency is widened, and vibration damping effect can be obtained in a wide frequency band. Hooks 16b, 16c are provided on the vertical plans to the central axis 16a in the connecting part 16, and fixed to the inertial body 15 and a fixture 17, whereby the dispersion of the natural frequency can be restricted to a small degree.

Title: Vertical synchronizing signal separator circuit
Inventor: FUKUTOMI SHINGO
IPC: H04N5/10
Filed: 1989-03-22
Abstract: PURPOSE:To correctly output a vertical synchronizing signal without being affected by noise by adding a noise elimination circuit eliminating the noise generated during the discrimination of a vertical synchronizing signal. CONSTITUTION:When a noise whose width is one clock width in a composite synchronizing signal COMPSYNC while a vertical synchronizing signal is discriminated, so long as the level of the COMPSYNC and a signal Qc retarded by a D flip-flop 1 is both logical 1, an output Sa of a logic element 11 goes to 1 to set an RS flip-flop 2. So long as the level of both the signals is both logical 0, an output Ra of the logic element 12 goes to logical 1 to reset the flip-flop 2. Thus, the input signal whose width is one clock or below is eliminated as noise and it is not included in an output Qo of the flip-flop 2 and not sent to flip-flops 3-7 for generating the vertical synchronizing signal. Thus, the correct vertical synchronizing signal is obtained at the output Q of the RS flip-flop 8.

Abstract: PURPOSE:To improve heat dissipation while the generation of package crack, the increase of cost, and the enlargement of equipment are restrained, by conducting the heat generated from a semiconductor device to a printed board via a metal plate excellent in thermal conductivity. CONSTITUTION:The other surface of a copper plate 7 is coated with adhesive agent excellent in thermal conductivity, and the copper plate 7 of a semiconductor device is bonded to the surface of a printed board 9.

Since the conventional package structure is applicable, package crack is not generated, and reliability can be improved.

Title: Logic gate circuit
Inventor: MORI SUSUMU
IPC: H03K19/088
Filed: 1979-06-07
Abstract: PURPOSE:To increase output dielectric strength by combining pulldown transistors with phase-dividing stage and output-side transistors. CONSTITUTION:When either input terminal 1 is held at a level of ''0'', input-side and power-side transistors Q1 and Q7 conduct and phase-dividing stage and output- stage transistors Q2 and Q3 become unconductive, so that an output terminal where output-side and pulldown transistors Q3 and Q4 are also cut off will be held at a level of ''1''. In this state, when a high voltage is applied to terminal 3 from the outside, prior-stage and post-stage transistors Q5 and Q6 of an off-buffer become unconductive and no current flows to the output until an enough voltage to break down the emitter junction between both the transistors. Therefore, when an electric power voltage is 5V in this case, the output voltage is 17V or more and when 0V, it is 12V, so that the output dielectric strength will increase remarkably as compared with the conventional dielectric strength of 6V, etc.

Abstract: PROBLEM TO BE SOLVED: To keep the concentration of hydrocarbon HC below an explosion limit by operating a fan for cooling a compressor constantly using a combustible refrigerant thereby stirring wet refrigerant by means of the fan. SOLUTION: When the temperature in a refrigerator detected by a temperature sensor 20 exceeds a specified level, a drive relay 19a is turned on under control of a microcomputer 21 to drive a compressor 1 in order to cool the inside of the refrigerator. On the other hand, a fan 2 connected directly with a power supply is driven constantly to supply chill for cooling the compressor 1 in order to prevent shortening of lifetime of the compressor 1 due to undue temperature rise. The compressor 1 is turned on/off by means of a switch 41 under control of the temperature sensor 20 and the microcomputer 21 and the fan 2 is operated constantly so long as power is turned on regardless of turn on/off of the compressor 1. Even when the HC refrigerant leaks in a machine room, it is stirred by means of the fan and HC concentration is held below an explosion limit.

Title: Misfire detecting device for internal combustion engine
Inventor: YONEZU TAKANOBU
IPC: F02P17/00
Filed: 1989-03-27
Abstract: PURPOSE:To surely detect the engine misfire in simple manners by utilizing the change of the magnetic flux by installing a magnetic flux-voltage conversion means for detecting the change of the magnetic flux which is generated by the ignition operation, onto the ignition equipment side. CONSTITUTION:When, an ignition switch 2 is turned ON, and an ignitor 4 is operated, a primary electric current flows in the primary coil 3a of an ignition coil 3 from a battery 1. Further, when the ignitor 4 is cut off, a high voltage is generated in the secondary coil 3b of the ignition coil 3. In this case, a Hall element 8 is installed onto the iron core of the ignition coil 3. A large output voltage is generated in the Hall element 8 according to the sharp variation of the magnetic flux in the normal ignition. Since, in case of misfire or leak at the edge of a spark plug, the magnetic flux does not sharply change, a small output voltage is generated in the Hall element 8. Therefore, the engine misfire can be surely detected in simple manners by utilizing the change of the magnetic flux.
