Title: Preparation of benzoin
Inventor: USUI MASAHIRO
IPC: C07C45/00
Filed: 1980-11-07
Abstract: PURPOSE: To prepare benzoin, in high yield, by dimerizing a crude benzaldehyde containing hydrocarbons as impurities in the presence of specific amounts of an alcohol, water and a catalyst, cooling and filtering the product, subjecting the filtrate to phase-separation, and recycling the aqueous layer to the reaction system.  
     CONSTITUTION: In the preparation of benzoin by the dimerization reaction of benzaldehyde, the reaction is carried out under heating in the presence of 5W 40wt% alcohol, 40W80wt% water based on said alcohol, and a cyan catalyst, using crude aldehyde containing hydrocarbons as impurities as the raw material. After the reaction, the reaction mixture is cooled and filtered to separate benzoin as solid crystals. The filtrate is separated into an oily layer containing the impurities contained in the crude benzaldehyde, and an aqueous layer consisting of alcohol, water and catalyst, and the aqueous layer is recycled to the reaction system. The benzaldehyde in the crude benzaldehyde can be utilized effectively resulting in the saving of resources.

Title: Liquid crystal display device
Inventor: MURATA MASAYOSHI
IPC: G02F1/1365
Filed: 1994-07-08
Abstract: PURPOSE:To prevent malfunction by generation of photocarriers even if the surface of a single crystal substrate is provided with peripheral driving circuits by installing a light shielding member at apart of the circumference of a counter substrate in the upper part of the peripheral driving circuits. CONSTITUTION:The part exclusive of pixel parts 506 on the counter substrate 502 are covered with the light shielding member 512. At this time, the counter substrate 502 is stuck to the single crystal silicon substrate 501 and thereafter, the counter substrate is provided with the light shielding member 512. Transparent points 512 are made opaque after the counter substrate 502 and the single crystal silicon substrate 501 are stuck to each other even if there are the transparent points 512 around alignment marks of this constitution. The circumferences of the alignment marks 510 and the circumferences of the sealing parts 503 are, therefore, made opaque and light does not reach the peripheral driving circuits formed of the single crystal silicon. The generation of the photocarriers in the peripheral driving circuits and the consequent malfunction of the circuits do not arise.

IPC: C08G63/181
Filed: 1995-06-23
Abstract: PURPOSE: To obtain an aromatic polyester which exhibits a liquid crystal behavior due to the orientation of polymer at a low temperature by reacting a specified esterified aromatic dicarboxylic acid compound having a long methylene chain with a diol. CONSTITUTION: An aliphatic alcohol (e.g. Unilin 425, a product of Toyo Petrolite Co.) having a molecular weight of 350 to 1,000 is reacted with a cyclic acid anhydride (e.g. trimellitic anhydride) to produce an esterified aromatic dicarboxylic acid compound having a long methylene chain. The obtained dicarboxylic acid compound is then reacted with a diol to give a polyester. An aromatic or aliphatic diol can be used as the diol. Examples of aromatic diol used include hydroquinone and bisphenol A. Examples of aliphatic diol used include ethylene glycol and butane diol. The obtained polyester is useful as, e.g. a component of an adhesive and an additive for improving the activity of a plastic.

IPC: G02B7/04
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a lens driving mechanism for camera capable of moving a photographing lens by using an electromagnetic device whose lowest actuation voltage is low. SOLUTION: A lens frame 5 where the photographing lens 4 is fixed is attached by a cylindrical lens holding member 6. In the member 6, a column 6f whose tip is fitted into the non-piercing hole of a base member 3 is erected, and the member 6 is energized by a coil spring 7. By fitting a hole 9a to the column 6a and bringing an abutting part 9d into contact with the base part 6e of the member 6, a lens regulating member 9 can move with a base part 9b as fulcrum. The member 9 is energized by a coil spring 10 whose energizing force is stronger than the spring 7 and pulls out an iron core 8a from an electromagnetic plunger 8 by using a branching part 9c. Therefore, in the case of energizing the plunger 8 and moving the lens 4, the plunger 8 only actuates the member 9 against the energizing force of the spring 10.

Filed: 1995-06-23
Abstract: PURPOSE: In the tractor which automatically brakes a rear wheel of the inner side of cornering with the operation of steering when cornering, to prevent the tractor from roughening a field because it digs the ground just after cornering. CONSTITUTION: When it is judged by a steering angle sensor 35 that a tractor 11 is in the area of cornering, if the tractor 11 is in a state of four-wheel driving and a predetermined time (about 1.2sec) does not elapse after a solenoid for increasing the speed of the front wheel, the solenoid for increasing the speed of the front wheel is turned on to corner the tractor 11 in a state in which the front wheel is being increased and four wheels are also driven. In addition, when the present over-run ratio (number of revolution of the front wheel/number of revolution of the rear wheel) is less than a standard over-run ratio, the solenoid for increasing the speed of the front wheel is also turned on to corner the tractor 11 in a state in which the front wheel is being increased and four wheels are driven.  Next, just after the tractor 11 begins cornering, a braking pressure is changed to a low pressure and a braking solenoid is turned on, thereby braking the rear wheel with a weak braking force to prevent roughening a field.

Abstract: PURPOSE:To remove resin burr easily and obtain a semiconductor device at a favorable yield rate by making tie bars exist up to places in the vicinity of resin sealing regions and forming notched parts having teach length which is almost equal to the thickness of a lead plate. CONSTITUTION:Tie bars 5 are extended up to places in the vicinity of resin sealing regions of leads 9. Notched parts 4 having each length which is almost equal to the thickness of a lead plate are formed at the tie bars 5 located at both sides of outer lead parts 3 of resin sealing region boundaries. Resin burrs which are produced in the case of resin sealing develop only in the notched parts 4. Removal of the resin burrs are thus performed easily simultaneously with cutting of the tie bars 5. Such a removal process eliminates the need for carrying out deburring. The resin burrs which are produced in the notched parts 4 are so fine that the crack development in a mold resin due to cutting impacts by the use of punch is thus prevented. Then a semiconductor device is obtained at a favorable yield rate.

Abstract: PURPOSE:To enlarge the contact areas and thereby reduce wear due to sliding by letting No.1 and No.2 piston which are slidably coupled with each other, come in contact with a power transmitting shaft and a driven shaft respectively at all times. CONSTITUTION:A piston which is interposed between a shaft 12 and a cylinder block 22 while torque is being transmitted between them, is made up out of 2 members, that is, No.1 piston 28 roughly in a cylindrical shape and No.2 piston 3O. Even if No.1 piston 28 and No.2 piston 30 are moved to any position, sliders 32 and 42 for the respective pistons come in contact with the shaft 12 and a driven pulley 20 via respective surfaces. As a result, both of the contact area of the piston with shaft 12 and the contact area of the piston with the driving pulley 20 are made large. By this constitution, the piston is brought into contact with the respective rotating shafts with surfaces at all times, and the occurrence of wear due to sliding at the contact places is therefore prevented, so that reliability can thereby be enhanced.
