Title: Preparation of unsaturated ether
Inventor: MANFUREETO KAUFUHORUTO
IPC: C07C43/16
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for simply producing an unsaturated ether, without almost producing high boiling point waste, capable of practicing at an ordinary pressure, in a slight amount of a catalyst used, by heating acetal or ketal in a specific carboxylic acid and only taking out a distillate.  
     SOLUTION: Acetal or ketal of formula I [R 1  is H or a 1-8C alkyl; R 2  is H, CH 3 , C 2 H 5  or Cl; R 3  is a 1-8C alkyl; R 4  is H, CH 3 , C 2 H, or C 2 H 5  or R 1  and R 4  together may form 5-7-membered ring] is heated in a high boiling, branched chain carboxylic acid at 100-250°C, especially 120-220°C. An unsaturated ether of formula II is obtained as a distillate on heating. The above carboxylic acid includes 5-20C carboxylic acid, especially 2,2-di-substituted 7-18C carboxyl, e.g. pivalic acid, neooctanoic acid or neodecanoic acid. This method can be practiced without using any catalyst. Further, the reaction can continuously be practiced. The method is a simple method suitable for decomposition of many different acetals and ketals.

Title: Multi-layered fiexible printed wiring board
Inventor: ICHIMASA SHIYOUJI
IPC: H05K1/02
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To improve resistance to noise and resistance to static electricity without attaching a countermeasure component such as a shield by forming a low impedance signal pattern having stable voltage over a large area on a part which is not to be used as a wiring pattern on a face opposite to the outer case of an electronic machine. SOLUTION: The multi-layered flexible printed wiring board 2 mounted on a camera body 1 is formed with a solid pattern 2c with a first face opposite to an armor. A foldback 2b is mounted by folding at a fold of a flexible printed substrate 2a. Thus the foldback 2b is facing the camera body 1, and a foldback on a lowermost face is opposite to the case of the camera. A solid pattern on the lowermost and the solid pattern 2c on the first face cause almost all faces of the mounted multi-layered flexible printed wiring board 2 opposite to the case to be a low impedance signal pattern having stable voltage.

Title: Controller for robot arm
Inventor: MATSUHIRA NOBUHITO
IPC: B25J9/16
Filed: 1985-10-29
Abstract: PURPOSE:To simplify the constitution of a controller for robot arm by using an analog circuit to a main servo system requiring a continuous or fast control cycle and using a digital computer to an arithmetic part for compensation of arm dead weight that requires a complicated arithmetic operation and a control cycle not so fast as the main servo system. CONSTITUTION:A master arm MA and a slave arm TA consist of a force servo system 1 and a position servo system 2 respectively. The system 1 functions to secure the coincidence between the torques of both arms MA and TA with the difference of torque sensors T1-Tn of both arms MA and TA. While the system 2 functions to make the arm TA follow the arm MA with the deviation of revolving angle sensors P1-Pn of both arms MA and TA. A dead weight compensating arithmetic part 3 consists of an A/D converter, a CPU and a D/A converter and calculates an empty weight torque from the signal of a sensor Pn of the arm MA to add it to the drive signal of a motor Mn of the arm MA. Thus the variation of the torque due to the dead empty weight can be compensated.
