Title: Spindle motor and disk driver provided with the motor
Inventor: SAITOU FUMIAKI
IPC: H02K29/08
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To improve unevenness of a rotation by providing an escape at a corner of a square hole having two sides parallel to a rotating direction and two sides perpendicular to the rotating direction on an outer periphery of a rotor, and inserting an index magnet. SOLUTION: In this spindle motor, a square hole 18 having two sides parallel to a rotating direction of a rotor and two sides perpendicular to the rotating direction is provided on an outer periphery of a rotor frame, an index magnet 27 of substantially rectangular parallelepiped shape is inserted into the hole 18, and fixed by using an ultraviolet curable adhesive. Thus, since a stator side part 23 of the hole 18 is not opened, the part 23 is operated as a shielding plate to generate no leakage magnetic flux. A leakage magnetic flux of the part protruding from the outer periphery of the frame 16 of the magnet 27 is attracted to the part 23 of the frame 16 so that a radius of a flying magnetic flux is reduced, a magnetic flux crossed with an FG coil 15 of a stator board 1 is reduced to improve an S/N ratio of an FG signal, and an unevenness of a rotation of the motor can be improved.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of an electronic component free of defective transfer without changing the processing conditions of excimer laser by providing the method for forming the groove shape without the catch of conductive paste and using such a concave plate. SOLUTION: A concave plate 1 having the shape of a groove 2 forming the obtuse angle of 90 deg. or more of an angle part 2a at the bottom surface is used and a pattern is formed. Thus, the defective transfer by the catch of conductive paste is eliminated. Furthermore, a mask 5, to which a line pattern 6a becoming the shade is added, is used at a part where laser light is applied at the angle part of the groove-bottom part. Thus, the concentration of laser energy at the corner part 2a of the bottom surface is avoided, and the groove shape such as this can be formed.

Abstract: PURPOSE: To use the combination of a magnetic ticket and a noncontact ticket and to improve the usability of the automatic ticket examination machine for a user by providing a control means reading ticket booking and ticket examining data from the magnetic ticket and the noncontact ticket and performing a ticket examination processing. CONSTITUTION: At first, a magnetic ticket C1 is inserted into the insertion port 1 of a main body (a) and, next, a noncontact ticket C2 is held up to a communication area 7. At this time, when the both of the magnetic ticket C1 and the noncontact ticket C2 are valid, a door 6 is opened, a user is given admission. At the time, the magnetic ticket C1 is returned from an ejection port 2. When the user goes not, the magnetic ticket C1 is collected within the body (a). When either one of the magnetic ticket C1 or the noncontact ticket C2 is invalid or both of them are invalid, the admission is naturally rejected. When the user can enter or goes out by only the inserted magnetic ticket C1 or only the held up noncontact ticket C2 , a ticket examination processing is performed by each single ticket. The processing may be performed by even plural of each ticket such as a magnetic ticket and a noncontact ticket or a magnetic ticket and two noncontact tickets.

Title: Data transmission system
Inventor: KAWASAKI KIKUO
Filed: 1984-11-19
Abstract: PURPOSE:To prevent transmission of erroneous data by providing a timer retarding the renewal of transmission data to a terminal device to absorb a time difference between related input signals at the terminal device side. CONSTITUTION:In receiving digital input signals Di1-Din from a digital signal input circuit 12 as representatives of input signals, when the input signal Di1 is changed at a point A and the change is detected, a delay timer starts operation. Since the delay timer does not complete its operation yet at a point (c), no renewal of transmission data is executed, and the same ata transmitted at points (a, b) are transmitted toward a center device from a terminal device. Although input signals Di2, Di3, Din are changing during the operation of the delay timer, each data relating to the state change is not transmitted but in stand-by. Then the data are renewed altogether at a point (f) after the operation of the delay timer as the transmission data including each change in thenput signals Di1, Di2, Din in stand-by so far, and transmitted to the center device.

Title: Manufacture of semiconductor pressure sensor
Inventor: YUKITAKE EIKI
IPC: H01L29/84
Filed: 1984-11-19
Abstract: PURPOSE:To manufacture a high-precision diaphragm and to improve yield by a method wherein a thermal oxide film is formed on one surface of an Si wafer and an epitaxial layer is formed on the other surface of the Si wafer, the thermal oxide film is removed, and then a diaphragm-forming process is accomplished on the surface wherefrom the thermal oxide film has been removed. CONSTITUTION:A wafer 2 is washed and then, on its rear surface, a thermal oxide film 23 is formed. The wafer 2 is then placed on a susceptor face of a support 3, with said rear surface of the wafer 2 facing down. The wafer 2 is then exposed to the silane gas at a high temperature, for the growth of an epitaxial layer 21. The gas reaches the surface covered by the thermal oxide film 23 and the epitaxial layer 22 formed thereon has an irregular surface. The thermal oxide film 23 is removed together with the irregular epitaxial layer 22 after completion of the growth of the epitaxial layer 21. The rear surface 24 of the Si wafer 2 is very flat and smooth because it has been protected by the thermal oxide film 23. This ensures the construction of a high-precision diaphragm. The surface 25 of such a diaphragm is very smooth, which results in an improved yield during the construction process.

Title: Heat exchanger
Inventor: SHIODA TATSUYA
IPC: F28D7/08
Filed: 1984-11-19
Abstract: PURPOSE:To reduce the thermal stress which tends to build up in the heat transmission pipe and its supports and simplify the vibration damping structure by changing the distance of the heat transmission pipe between the support points at various locations and differentiating the natural frequency relatively between the neighboring sections. CONSTITUTION:In the heat transmission pipe 3 of a heat exchanger, the length of the straight pipe section which is connected to upper and lower curved pipes 5A, 5B is Panot equal to Pb, and the upper and lower position of the heat transmission pipe 3 are alternated every other time in the direction of parallel connection. By this arrangement, the heat transmission pipe 3 has different inertia moment vertically and in the direction of the row in reference to the connecting distance and shape of the curved pipes 5A, 5B, i.e. a pair of supports S. Since there is a difference in the natural frequency, those parts which are adjacent to the curved pipes 5A, 5B will not resonate, and so, the external force inflicted to the support S can be reduced. As a result, the support member 6 is disposed only at one position in the center, and a vibration damping plate 8 is attached to a support frame 7 to hold the curved pipes 5A, 5B in between so as not to impair the thermal displacement due to the thermal expansion and contraction of the heat transmission pipe 3.
