Title: Detention needle
Inventor: KOZAI TADASHI
IPC: A61L29/00
Filed: 1989-11-17
Abstract: PURPOSE:To ensure the nerve of a catheter during insertion of it in a blood vessel and to improve insertion operability by a method wherein hardness and repulsion elasticity of a catheter material are specified. CONSTITUTION:A catheter is formed of a material having a hardness of Shore D50-70 and repulsion elasticity of 40% or more. When hardness of the catheter material is below Shore D 50, a nerve necessary to the catheter can be ensured. Namely, when hardness of the catheter material exceeds Shore D 50, a nerve necessary to the catheter can be ensured, and excellent insertion operability can be ensured. When repulsion elasticity of the catheter material is below 40%, plastic deformation occurs and recovery is low, and a curl is easy to be left as it is. Namely, since repulsion elasticity of the catheter material exceeds 40% and enough, a curl is difficult to be left as it is. The catheter can smoothly follow bending of a detention portion due to movement of an arm during detention of a needle in a blood vessel, and excellent detention stability can be ensured.

Title: Disconnection detector for electric motor
Inventor: NAKAJIMA HIROSHI
IPC: B62D5/04
Filed: 1994-12-02
Abstract: PURPOSE: To suppress rotation of a rotor during a conduction time for detecting the disconnection by deciding whether a current detection means detected a current higher than a predetermined level upon elapse of a predetermined short time after conduction of a motor drive is designated and then designating brake conduction if it is not detected. CONSTITUTION: Transistors are conducted sequentially to feed a current to a motor 12. Current level detected by a current detection circuit 86 in a motor driver 5 (more specifically, the level of output signal M11 from a peak hold circuit 101) is then read in and a decision is made that the motor is not disconnected if the current level thus read in is higher than a reference level β otherwise a decision is made that the motor is disconnected. Since the conduction time for detecting the disconnection is limited to predetermined short time interval after conduction of the motor driver 5 is designated before the current flowing through a normal winding in the motor 12 reaches a predetermined level, the rotor rotates only a micro amount. When the motor is normal, the rotor tries to rotated with dynamic inertia, but the inertial rotation is blocked through brake conduction.  This arrangement can prevent offensive noise sounding to the car body.

Title: Manufacture of thin-film photovoltaic element
Inventor: ISHII MASAYUKI
IPC: H01L31/04
Filed: 1987-11-27
Abstract: PURPOSE:To obtain a thin-film photovoltaic element having less defect level of a p/i boundary and excellent characteristics by diluting silicon compound concentration in material gas with hydrogen when an i-type Si film is started to be formed on a p-type a-Si film to set it to 5-50vol.%, and then increasing the silicon compound concentration. CONSTITUTION:After an i-type a-Si film is started to be formed, silicon compound concentration in gas material is increased as a time goes or intermittently, and so set to the concentration of 50-100vol.% as to obtain a film growing speed adapted for its mass production. It is preferable to raise to the concentration range of 50-100vol.% as fast as possible, and to then grow the film at a predetermined concentration, and the time until the silicon compound concentration in the gas arrives at a predetermined concentration is 10sec-5min. Thus, since a stable plasma state is obtained from the initial time of growing an i-type amorphous silicon film, a p/i boundary having less defect level is formed, the amorphous silicon film can be formed at a film growing speed adapted for its mass production, and a thin film photovoltaic element having excellent characteristics can be inexpensively obtained.

Then a four-way valve 8 is changed over and gas A of the duct 13 is passed through the tower 3 via the four-way valves 8, 9 to perform cooling of the drying agent. Since the gas A flowed out through the tower 3 is made to high temp. in the first stage of cooling, it is used to perform heating and regeneration of the tower 16 via a four-way valve 7 and the flow path 14. The gas A is descended in temp. and the sub-tower 16 is cooled by the processing of cooling of the tower 3.
