Title: Ignitor for internal combustion engine
Inventor: TSUTSUI MITSUKUNI
IPC: F02P15/00
Filed: 1977-09-30
Abstract: PURPOSE: To provide an ignitor of small size and high reliability by constituting same such that an earth electrode is interposed between an ignition coil and electronic circuitry of an amplifier so as to prevent the ignition coil from influencing the amplifier.  
     CONSTITUTION: Conductive coating material 48 coated on an ignition coil is interposed as an earth electrode between an integrafted circuit and terminals of an ampifier 2 and a high potential secdtion of a secondary coil. Thus, the integrated circuit is shielded frm the high potential section of the secondary coil. Even if the integrated circuit is arranged adjacent te high potential section of the secondary coil, it is not influenced by the secondary coil, it is influenced by the secondary coil. Moreover, since the section on which the conductive coating material 48 is coated as an earth electrode is in a shape which has no pointed section relative to the high potential section of the secondary coil, there appears no electrostatic focusing, which makes it difficult for corona discharge to appearthereabout. Accordingly, the voltage withstanding performance of the ignition coil is widely improved

Title: Aluminum alloy foil for electrolytic capacitor
Inventor: ARAI KOUZOU
IPC: H01G9/04
Filed: 1981-07-24
Abstract: PURPOSE: To reduce loss on etching and to increase the electrostitic capacity of foil by adding a prescribed amount of Bi to Al having a specified purity or above.  
     CONSTITUTION: The titled alloy foil is obtd. by adding 0.00005W0.001wt% Bi to high purity Al having ≥99.9wt% purity. When Al is etched after adding such an adequate amount of Bi, the density of surface recesses of foil is increased. Accordingly, the electrostatic capacity of the foil is increased.

Title: Vapor growth device
Inventor: KONDO KAZUAKI
IPC: H01L21/205
Filed: 1990-05-08
Abstract: PURPOSE:To give a gradient to the temperature distribution of a susceptor in the direction to offset a film thickness distribution and to make even a film thickness by a method wherein the contact heat-transfer areas of the susceptor to wafers are made larger in the center of the susceptor and are made smaller toward the periphery of the susceptor. CONSTITUTION:A susceptor 13 with wafers 11 supported on both surfaces of the susceptor 13 is fixedly held on a common susceptor supporting stage 17. Heat generated by heating heaters 15 arranged on the periphery of a furnace core tube 10 is transmitted to the wafers 11 via the susceptor 13 which is used as an induction heat-transfer means. As the temperature of the peripheral part of the susceptor becomes higher than the temperature of the center part of the susceptor, a plurality of pieces of concentric circle-shaped grooves 31 are formed in the susceptor 13, the groove width of the groove in the center of the susceptor is specially formed small and the groove width of the grooves in the peripheral part of the susceptor is specially formed large. That is, the smaller the contact areas of the susceptor 13 to the wafers 11 are specially made in the peripheral part, the smaller a heat-transfer efficiency is specially reduced in the peripheral part and the temperature distribution of the susceptor can be made even.

Title: Amplifier circuit
Inventor: NORO MASAO
IPC: H03F1/32
Filed: 1986-05-21
Abstract: PURPOSE:To obtain a low distortion output signal without crossover distortion by impressing an input signal to a non-inverting input of the 1st operational amplifier, superimposing a DC bias onto its output signal and impressing the result to a non-inverting input of the 2nd operational amplifier. CONSTITUTION:An output voltage V1 of an operational amplifier 2 is a voltage changed only at a positive region because an output stage of the said operational amplifier 2 is biased positively. Since an output stage of an operational amplifier 3 is biased negatively, a voltage V2 is varied in the negative region only. The voltages V1, V2 are combined via resistors 7, 8, and the result is outputted from an output terminal 9 as an output voltage Vo. Since the output voltage of the operational amplifiers 2, 3 is varied respectively in the positive and negative resion only, the output stage of the operational amplifiers 2, 3 acts like the class A operation. As a result, no crossover distortion is caused in the output of the operational amplifiers 2, 3 and the output voltage Vo with low distortion is obtained.

Next, in case the thermister 5 is out of order due to shortcircuiting, the negative potential of a voltage comparator 33 is elevated up to a power source voltage and therefore, the output of the comparator 33 is kept ON but since the Tr9 goes OFF and the Tr8 goes ON due to the shortcircuiting of the thermister 5, a base current flows through the Tr7 through a resistor 14 to turn Tr17 ON. Consequently, a contact 35 of a relay 30 is opened, the circulation pump 4 is operated and a LED32 gives forth light to display an alarm.

IPC: H01L27/06
Filed: 1990-05-08
Abstract: PURPOSE:To prevent absorption of boron into an oxide film and to reduce dose of ion implanting by implanting boron of a channel stopper after a field oxidizing step. CONSTITUTION:The same manufacturing method as a conventional one is employed up to a step of forming a channel stopper layer 106 of an n-well. Then, after resist is peeled, a thermal oxide film 107 is formed. Thereafter, a nitride film covering the active region of a transistor is removed. Then, resist 108 is so patterned as to open a P-type well region, and boron is implanted. Thus, since the boron is implanted after the field oxidation, it is not absorbed to the field oxide film, and the impurity to be implanted can be reduced.

Title: Golf ball made of ice
Inventor: FUKASHIRO MASAYOSHI
IPC: A63B43/00
Filed: 1990-05-08
Abstract: PURPOSE:To provide a safe and inexpensive golf ball providing nearly the same comfortable feeling as in the case of hitting a true golf ball and practically having exercise effect by making the golf ball with ice. CONSTITUTION:A material is formed by freezing water to make ice and cutting a mass of ice by means of machine, or pouring water into a mold having a golf ball form, followed by freezing. As an ice golf ball 1 is broken into pieces by an impact, it is not dangerous even if it flies far. Thus, no dimple for improving the flying distance is not required, and further, as a net is also not required, any open space such as park, field, and river may form an instant exercising space for hitting practice, and a person can hit the ball toward it with a vengeance. Further, whether a club head precisely hit the center of the ball can be judged from the broken state of the ice ball. As the scattered ice pieces are melted into water and then evaporated, their collection is not required, and they are non-polluting.

Abstract: PURPOSE:To print out a normal picture even when a disturbed external synchronizing signal is inputted by using a location comparator circuit applying pulse width comparing in place of the phase comparator circuit comparing edges so as to use the frequency division output of a reproduced dot clock as a reference for position comparison. CONSTITUTION:An output 6 of a position comparator 5b applying pulse width comparison of an external synchronizing signal and a comparison use synchronizing signal 4 is a control voltage of a VCO 1 via a filter 7. Thus, in the case of a normal external synchronizing signal, the same waveform as that of a conventional circuit is generated at an output 6 and the same operation as a conventional circuit is attained. On the other hand, when a synchronizing signal is generated at a position deviated from the normal position or missing, the locking to the synchronization is attained immediately when the normal external signal comes next, resulting in obtaining a normal print picture.
