Title: Selective hydrogenation of compound having acetylenic unsaturated bond
Inventor: KINOSHITA SHIYOUICHI
IPC: C07C33/02
Filed: 1979-11-30
Abstract: PURPOSE: To carry out the selective and quantitative hydrogenation of an acetylenic unsaturated bond to a carbon-carbon double bond, by using a Pd catalyst and a reaction suppressing agent comprising a thiourea such as N,N'-diethyl thiourea.  
     CONSTITUTION: A compound having at least one acetylenic unsaturated bond (especially effective to acetylene alcohol) is hydrogenated in the presence of a Pd catalyst to obtain a compound having an ethylenic unsaturated bond (e.g. 3,7,11- trimethyl-1,6,10-dodecatrien-3-ol). The hydrogenation is carried out by adding a thiourea of formula I [R and R' are H or 1W8C alkyl, or R and R' may together form an alkylene of formula II (R 1  and R 2  are H or 1W5c alkyl; n is 2 or 3)] (e.g. ethylene thiourea), to the reaction system.

Title: Acoustic equipment having function for selecting music by card
Inventor: YOKOTA TOKUO
IPC: G11B7/00
Filed: 1990-06-12
Abstract: PURPOSE:To make the equipment quite profitable so as for a user to easily select music and to sing the song while observing the lyrics corresponding to the music to be reproduced by loading a card printing the lyrics to the main body of the equipment. CONSTITUTION:First of all, a card 11 for desired music is inserted to a slit 14. By this operation, it is transmitted to a control microcomputer 29 that a detection switch 17 is turned on to request the music. Then, a phototransistor at a position counter to a hole 13 of the card 11 is still left in an ON state since the light of a light emitting diode reaches, and the other phototransistors, however, are turned to an OFF state. Therefore, the control microcomputer 29 can obtain an identification signal according to the state of each phototransistor and as the result, the track number of the music to be selected can be recognized. Then, after moving a pickup 19 to a track corresponding to the identification signal, a reproducing operation is started.

Title: Lever connector
Inventor: KITAMURA YUTAKA
IPC: H01R13/629
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce the moving amount of a lever and obtain large leverage effect by linearly sliding a cam slide and the lever until terminals approach each other before the rotation of the lever. SOLUTION: When a lever 6 is linearly pulled in the arrow B direction, projections 14a, 14b of the lever 6 slide within long holes 24, 22, and strike against the end parts of the holes and stop. A cam slide 32 also moves in the arrow B direction through a projection 20 of the lever 6 and a long hole 34 of the cam slide 32. Cam followers 154, 174 are pressed inward, and connectors 150, 170 are drawn inward. Connectors 150, 170 are smoothly inserted with almost no resistance until terminals approach each other, therefore, the lever 6 is easily drawn by small force. When the lever 6 stops in the struck position, a connecting part 10 projects to the outside of a connector main body and the rotation is made impossible, and by rotating on the projection 14b, terminals are smoothly fitted each other by the effect of leverage mechanism.

Title: Helix changing power source for travelling-wave tube
Inventor: UORUTERU BUIKEMA
IPC: G01S7/282
Filed: 1988-06-24
Abstract: PURPOSE: To accurately provide a switching power source for generating the helix voltage for a traveling-wave tube by controlling switches with a control circuit via the signal which is the function of a pulsating load and the rhythm of the voltage applied to a buffer. CONSTITUTION: When switches 3A, 3B are concurrently closed, a current source 6 feeds a constant current Is . The current Is passes through the switches 3A, 3B from the positive terminal of a DC voltage source 1, and it flows to the negative terminal of the DC voltage source 1 through a current converter 7. The current Is flowing on the primary side 9 determines the primary voltage of a transformer 8, thus it determines the current Ic flowing on the secondary side 11. A buffer 12 is charged by the current Ic on the secondary side 11 via a diode 10, therefore the charging current of the buffer 12 directly depends on the value of the current Is flowing on the primary side 9. When the switches 3A, 3B are opened by a control circuit 5, the current Is flowing on the primary side 9 becomes zero.  The magnetization energy in the transformer 8 is returned to the DC voltage source 1 via diodes 13A, 13B.

Title: Image input and output device
Inventor: HASHIMOTO SHUNICHI
IPC: H04N1/04
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To surely prevent a malfunction only at the time of abnormality by stopping the power supply of a driving motor when a state that an image input and output means erroneously exceeds the maximum range of moving at the time of normal operating and can not move any more is continued longer than fixed time. SOLUTION: At the point of time when a voltage at a point A exceeds a voltage at a point B, the output of an analog comparator 25 (a waveform at a point C) changes from low level to high level. Since a 2nd carriage collides with a side plate and can not move any more, the state of overload is continued and even after the lapse of prescribed time, the state of making the voltage at the point A higher than the voltage at the point B is continued. Then, a voltage at a point D gradually increases and finally exceeds the threshold value of clock input of a flip-flop 26, and the inverse of Q output of the flip-flop 26 (a waveform at a point E) turns low level. Then, the output of a two-input AND gate 27 turns low level in spite of a motor driving signal, and a carriage motor 8 is forcibly stopped.

Title: Liquid crystal display device
Inventor: AKUNE YOSHIHIRO
IPC: G02F1/1333
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent fluctuation in the liquid crystal caused by ridges of a housing by chamfering the ridge part on the edge of the opening of the housing facing to the back face of a liquid crystal panel. SOLUTION: For example, in a LCD module, a liquid crystal panel 3, sheets 4 to 8, light transmitting plate 9 are tightly stacked and housed between a metal frame 1 and a resin housing 2. Openings 2a to 2e are formed in the housing 2, and ridges 2f to 2h of the housing 2 on the edge of the openings 2a to 2e facing to the back face of the liquid crystal panel 3 are chamfered and rounded. The chamfering amt. is controlled to the equal to the thickness of the housing 2 on the edge of the openings 2a to 2e. In the LCD module after chamfered and rounded, the ridges 2f to 2j of the housing do not act like protrusions even in the tightly stacked and housed structure of the liquid crystal panel 3, sheets 4 to 8 and light transmitting plate 9, and therefore, normal operation such as touching keys or the like hardly causes vibration to be transmitted to the liquid crystal panel 3.

Filed: 1978-12-20
Abstract: PURPOSE: To separate a mixture containing isomers of hydrocarbon group-substituted phenols into its components, in high efficiency, by using an adsorbent comprising magnesium oxide having different adsorption selectivity to each isomer component.  
     CONSTITUTION: A mixture containing isomers of hydrocarbon-substituted phenols such as cresol isomers, xylenol isomers, etc., is treated with an adsorbent containing magnesium oxide, at 0W300°C, pref. 10W200°C. The adsorbed amount of each isomer depends upon its adsorption selectivity. The isomers adsorbed to the adsorbent are desorbed by conventional means, and again adsorbed to the MgO-containing adsorbent. By repeating the procedure, the mixture can be separated into its components according to the ratios of their adsorption selectivities. The magnesium oxide is supported by or attached to a carrier such as silica or alumina.

Abstract: PURPOSE: To improve the yield of a semiconductor device of pressure contact type in the structure that emitters and base regions are alternatively combined by detecting abnormal emitter electrode in bonded state, removing it and operating turn-off only by the normal electrode.  
     CONSTITUTION: An anode 10 is secured to a p-ty0e emitter layer 5 side of a semiconductor substrate 1 having an n-type base layer 4 and the layer 5 using brazing filler 8, and a p-type base layer 3 is formed on the layer 4. Then, continued n-type emitter region 2 of slender short fence state is diffused in the layer 3, coated by a mask, etched at the layer 3 to thereby reduce the thickness of the layer 3, and a gate electrode is then mounted thereon. A plurality of emitter electrodes 6 are then mounted on the region 2 continued and projected, cathodes are placed thereon to thereby measure gate trigger voltage and current between the electrodes 6 and 7. If there is any malfunction in any of these, it is photoetched to thereby remove the electrode 6 of this portion.
