Title: Joint made of shape memory alloy
Inventor: AMANO KAZUO
IPC: C22C19/03
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To facilitate and rationalize piping replacement work by providing the outside surface of a cylindrical liner with grooves having parts penetrating this cylindrical liner and forming shape memory allay rings and the cylindrical liner to a fit structure. SOLUTION: The shape memory allay rings 1 are manufactured by using shape memory alloys. These allays are made to memorize a shape in such a manner that the diameter thereof is reduced by heating the allays to their austenitic transformation temp. or above. The cylindrical liner 2 to be inserted into the inner side of the shape memory allay rings 1 is provided with two rows of annular projecting parts 3a, 3b in its circumferential direction and the outside surface is provided with the grooves 5 having the parts penetrating the inside of the liner. When the shape memory alloy rings 1 restore the shape to the reduced diameter by inducing the austenitic transformation, the cylindrical liner 2 is deformed and the annular projecting parts 3a, 3b formed on its inside surface bite into a piping, thereby clamping the piping.  In such a case, the rigidity of the cylindrical liner 2 is enhanced if the width of the grooves 5 on the outside surface of the cylindrical liner 2 is made small and the number of the grooves is reduced.

Title: Device for optical data processing
Inventor: TAI SHUICHI
IPC: H01L27/15
Filed: 1993-03-31
Abstract: PURPOSE:To provide an optical data processing device comprising a two-dimensional matrix of variable-sensitivity photodetectors free from effects of capacitance by irradiating the photodetectors with light after sensitivity control voltage is applied to them. CONSTITUTION:MSM-PDs 4 (variable sensitivity photodetector) are arrayed two-dimensionally. An active matrix driver circuit applies sensitivity-control voltage to the MSM-PDs through drain buses connected with a hold circuit 12. After the control voltage is applied through a pass of frame scanning via capacitors 10, a light-emitting array is turned on and the photocurrent in the MSM-PDs is sampled. This removes the effects of differentiation current, and it is possible to form an optical data processing device capable of high frequency operation.

Title: Secondary controller for 3-phase induction motor
Inventor: CHIBA HIROSHI
IPC: H02P21/34
Filed: 1987-04-20
Abstract: PURPOSE:To eliminate a secondary switching contactor of large capacity by connecting a nonlinear resistor and a secondary exciter in parallel with the secondary terminal of a wound-rotor type 3-phase induction motor. CONSTITUTION:The secondary voltage of a motor is held at a breakdown voltage by a clipping action in a low resistance value range of a nonlinear resistor 3 at the time of starting the motor. Thus, a necessary starting torque can be obtained while the starting current of the motor is suitably suppressed. When the motor speed is raised to the operating range of a secondary exciter 4, the secondary voltage of the motor becomes the breakdown voltage or lower of the nonlinear resistor, and the resistor 5 becomes a high resistance value range. Thus, the separation of the resistor by the secondary switching contactor is unnecessitated.

Abstract: PURPOSE:To optimize the power conduction time by adding a predetermined rotation to an operated value of engine rotation at an input time point of a referential signal thereby operating a time interval between acceleration predicting referential signals and setting a power conduction starting time based upon said time interval. CONSTITUTION:Based upon a time interval between referential signals for every predetermined crank angle of a detecting means (a) being measured by a time measuring means (c), an ignition timing operating means (d) calculates the optimal ignition timing according to an operating condition of engine being detected by a detecting means (b). An acceleration predicting means (e) adds a predetermined rotation to a rotation at said operating time point so as to obtain a time interval between acceleration predicting referential signals then a time operating means (f) obtains a time interval to the next ignition timing based upon the time interval between acceleration predicting referential signals so as to set a power conduction starting time thus controlling an ignition means (f) through a drive means (g). Consequently, the power conduction timing can be optimized irrespective of the operating conditions thereby the power consumption is reduced and the misfiring can be prevented.

Title: Exposure device
Inventor: KAMIYA SABURO
IPC: H01L21/027
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce the sound of a frequency in the vicinity of the mechanical resonance frequency of an exposure body part by a method wherein at least one part of the components of the sound of the frequency in the vicinity of the mechanical resonance frequency peculiar to the exposure body part is removed from among noises, which are generated in the interior of an air-handling part. SOLUTION: In this exposure device 10, an air fan 48 provided in a utility room 16 is constituted by using a centrifugal fan consisting of a turbo-fan and a radial fan. As these of the turbo-fan and the radial fan reduce noise to a noise level of not more than 200Hz or thereabouts compared with a sirocco fan which has been hitherto used, the generation of the sound of a frequency in the vicinity of the mechanical resonance frequency of a exposure body part 14, which is generated from the air fan 48, can be suppressed. That is, in the exposure device 10, a noise removal means is constituted of the air fan 48 constituted by using the centrifugal fan, which consists of the turbo-fan and the radial fan. Moreover, in this case, in respect to noise in the sense of a human being, there is not any trouble in a semiconductor factory in which automated system operations are almost conducted.
