Title: Production of cyclic alcohol
Inventor: MORI HIROSHI
IPC: C07C35/02
Filed: 1995-03-06
Abstract: PURPOSE: To obtain a cyclic alcohol in high yield and in stabilized quality by catalytic hydration of a cyclic olefin in the presence of a specific zeolite catalyst excellent in hydration activity.

Title: Heat insulating door
Inventor: KAI HIDEKAZU
IPC: F25D23/08
Filed: 1988-02-26
Abstract: PURPOSE:To prevent thermal deformation of a heat insulating door, by a method wherein a shrinkage absorbing material to absorb relative thermal displacement between a door frame body and a foaming heat insulating material is situated between the frame body and a foamed heat insulating material with which the interior of a closed space is filled. CONSTITUTION:After a door inner plate 3 having a shrinkage absorbing part 16 formed by a soft urethane foam is mounted to a jig for foaming, it is assembled integrally with a door frame body 1 and a door outer plate 2, and a foaming heat insulating material 7 is foam-molded in a closed space therein to form an integrally bonded heat insulating door. In the so formed heat insulating door, in a heat dissipation state after foam-molding of the foaming heat insulating material 7, a difference in a relative thermal shrinkage amount between the foaming heat insulating material 7 and the door inner plate 3 is absorbed through deformation of the soft urethane foam of the shrinkage absorbing part 16 by means of flexibility. Thereby, displacement of the foaming heat insulating material 7 due to thermal shrinkage or a tensile force by which the door inner plate 3 is caused to shrink due to displacement are absorbed by the shrinkage absorbing part 16, and deformation of the door inner plate 3 is prevented from occurring.

Abstract: PURPOSE: To prepare a cycloalkanone smoothly and economically, by reacting a cycloalkanol with a hypohalite of an alkali metal or an alkaline earth metal in water and a water-miscible organic solvent under acidic conditions.  
     CONSTITUTION: A cycloalkanol of formula I (m is 0-5; the carbon atoms may be mono-substd or di-substd. by alkyl, alkoxy, F, Cl or Br), e.g. 4-tert.- butylcyclohexanol, is reacted with a hypohalite solution in an aqueous/water- miscible organic solvent at a pH of ≤6 to form easily a cycloalkanone, e.g. 4-tert.-butylcyclohexanone. Since the present process does not employ oxidizing agents which are troublesome in environment and expensive catalysts, it has advantages in cost. Also, the present process does not require any special apparatus. According to the present process, a cycloalkanone which is optionally substituted is obtained in high yield with high purity.

IPC: H03K19/017
Filed: 1979-04-14
Abstract: PURPOSE:To make a high speed operation coexist with an increase of fan out number in an integrated circuit by a method wherein a positive operated SIT is used for switching and plural Schottky barrier diodes are prepared at its drain. CONSTITUTION:An n<->-epitaxial layer 16 on a p-type Si 12 having an n<+>-buried- layer 14 is divided with p-layers 18, and Al layers 24, 26 are attached. In this constitution, the channel of SIT is in the n<->-layer part surrounded with the p<+>-layers 20, and is made to be pinch off by a depletion layer extended from the gate layer 20 when a gate G is biased at zero against a source S. The n<+>-buried-layer 14 and the n<->-layers under the Al layers 24, 26 act as a drain D. Moreover the Al layers 24, 26 constitute Schottky diodes D1, D2 and respective drain output is decoupled. Therefore, when SITQ is made to on state, a current is drawn in through the Schottky diodes, and current hogging does not occur and electric charge does not accumulate. By this way, a device prepared with a SIT having a large number of fan out and high speed operation can be obtained.

Title: Grinding apparatus for generation of spark
Inventor: YONEZAWA KOJI
IPC: G01N19/06
Filed: 1995-03-07
Abstract: PURPOSE: To stably generate sparks in a method for determining components of a steel material. CONSTITUTION: A grinder consisting of a whetstone 5 and a driving motor 6 and a counter weight 8 are set to a grinder-supporting arm 4 having a fulcrum at a supporting shaft 3 of a mounting part 1.

Title: Driving control circuit for opening section opening or closing motor

IPC: E05F15/41
Filed: 1992-02-03
Abstract: PURPOSE:To obtain the torque controlling circuit of a motor for preventing a motor rotating speed from being lowered at a normal time and using a battery capacity effectively. CONSTITUTION:When an excess load is worked on a motor in a state that current is fed to the motor 1, then the potential of the inversion input terminal of a comparator 28 is increased, and to AND gates 11, 61, the signal of a low level is fed, and so transistors 6, 56 are tuned OFF, and accordingly, the feed of current to the motor 1 is interrupted. Then, the potential of the inversion input terminal is lowered again, and so said working is inverted, and the current is fed to the motor 1. Accordingly, only when a load is worked on the motor, then by chopping feed current, motor torque is controlled, and so without losing a battery capacity, torque can be controlled, and at a normal time, a motor rotating speed is not delayed.
