Title: Optoelectronic device and manufacture thereof
Inventor: NEMOTO TSUGIO
IPC: H01S5/00
Filed: 1988-04-15
Abstract: PURPOSE:To perform optical axis adjustment with high accuracy even by use of the outer face of a package as a reference, by providing a reference face which is formed at the outer face of the package on the basis of the optical axis of an optical element. CONSTITUTION:The circumferential face of the periphery of a cap 4 which is used as a reference face 14 forms itself into a circle which is centered by an optical axis 15 of a laser beam 10 emitted by a laser diode chip 9 and it is formed after a cutting work which is performed on the basis of detection of the optical axis 15. As to alignment accuracy between the reference face 14 and the optical axis 15, it is at least within + or -10mum. It is due to the fact that the fitting accuracy of a receptacle 16 for guiding an optical fiber towards a ring-type coupler 17 is required to be, for example, less than + or -10mum. In the case of this semiconductor laser device 1, if its cap part 4 is fitted into the coupler 17 of the receptacle 16, optical coupling is performed automatically with desired accuracy.

Title: Vane pump
Inventor: YAMAGUCHI KATSUHISA
IPC: F04C28/22
Filed: 1994-04-28
Abstract: PURPOSE:To facilitate adjustment of the discharge state by switching the maximum discharge amount into the small flow rate through a process of moving a piston by the specific amount after introducing discharge pressure liquid into an operating chamber by means of a pressure control valve when the discharge pressure is increased to the intermediate pressure, and by cutting off the maximum discharge amount to the minimum discharge amount when the discharge pressure is increased to the maximum discharge pressure. CONSTITUTION:When the discharge pressure is increased and pilot pressure to a pressure control valve 64 is increased and it becomes the intermediate pressure or more set according to energizing force of a spring 66, the pressure control valve 64 is switched from the maximum discharge position (a) to the intermediate discharge pressure position. Thereby, pressure liquid is introduced into an operating chamber 54, and a piston 46 moves a cam ring 4 by the specific amount against energizing force of an energizing member 18, so as to make the piston come in contact with the bottom part 43 of a sliding hole 42. Thereby, the maximum discharge amount is switched from the large flow rate to the small flow rate. When the discharge pressure is further increased to the maximum pressure, the cam ring 4 is moved to the position where the eccentric amount of the cam ring 4 and the rotor 6 becomes the minimum, and the discharge amount is cut off to approximately zero.

Filed: 1979-07-19
Abstract: PURPOSE: To improve an absolute precision, by using a magnetoresistive element consisting of the ferromagnetic material this film having uniaxial anisotropy and by patterning the magnetization pattern of a magnetizing material by photoetching.  
     CONSTITUTION: Magnetizing material 1 and magnetoresistive element (MR element) 2 consisting of the ferromagnetic material thin film having uniaxial anisotropy are arranged oppositely to each other. Magnetizing materials 1 are provided in parallel at an equal interval on substrate 3 by patterning dependent upon photoetching. The leakage magnetic field in the (y) direction generated from magnetizing material 1 is detected by transfer of MR element 2 in the (x) direction. The magnetization direction of magnetizing material 1 is the (x) direction as shown by the arrow. Thus, fluctuation of the detection output dependent upon fluctuation of the relative speed between magnetizing materials and the head, which is generated by using the magnetic flux response type head, is not generated by using the MR element, and the absolute precision can be improved sufficiently because magnetizing materials 1 are patterned by photoecthing.

Filed: 1989-04-11
Abstract: PURPOSE:To save the cost for a computer for fault detection and evaluation and to utilize the knowledge and information property of a designer by checking a specified detection internal signal state in a fault dictionary and deciding fault detection. CONSTITUTION:Normal circuit connection information 4a is read in first and simulation 4d is performed for input test pattern information 4c to generate simulation result information 4e on an internal signal. Then the information 4e is used to check whether or not a circuit is put in a detection state corresponding to respective faults in the fault dictionary 4h. When detection state information in the dictionary 4h matches state information of the information 4e at a certain time, it is considered that a fault is detected. Namely, when a 0-fixed fault 7f is assumed in the object circuit 7 of fault detection and evaluation, fault dictionary contents description 6a shows that the fault SAO of a signal PORT can be detected when fault detection and evaluation signals 7a and 7f are both 0 and fault detection signals 7c and 7s are both 1. Further, the dictionary 4h may be generated by the designer manually or generated automatically by using simulator information on partial circuits.
