Title: Preparation of conductive tin oxide powder
Inventor: YOSHIZUMI MOTOHIKO
IPC: C01G19/02
Filed: 1989-01-26
Abstract: PURPOSE:To give stable conductivity by treating a SnO2 powder with a fluorine gas in a ratio within a specified range. CONSTITUTION:A SnO2 powder is brought in to contact with an inert gas containing 10-40vol.% of fluorine gas to dope SnO2 with fluorine and give conductivity to the powder. In the case that the concentration of fluorine is less than 10vol.%, fluorine is difficult to be doped in the powder and conductivity becomes low. Also, in the case of more than 40vol.% of the concentration, reaction becomes intense and the SnO2 powder becomes blakened and the concentration is improper. The temperature at which the SnO2 powder is brought into contact with fluorine gas is preferably in a range of 300-600 deg.C.

Title: Magnetic disk
Inventor: NAKATANI MORIHIRO
IPC: G11B23/00
Filed: 1989-01-26
Abstract: PURPOSE:To simplify the loading action of a magnetic disk and at the same time to prevent the eccentricity of a rotary system by forming an approximately triangular hole defining a flexible part as one side at an inner circumferential part of the disk and bending the flexible part to produce the pilot pressure and at the same time to position the disk. CONSTITUTION:A disk 9 has a hole at its center part to hold a spindle motor hub 1 and specifies the shape of the hole so that the disk 9 is positioned via the cylindrical surface of the hub 1 and three areas. The inner circumference of the disk 9 has an approximately triangular shape having a flexible part 8. Thus the relative position of the disk 9 is well-definedly and stably decided while it is pressed toward an arrow 7 with the bend of the part 8. When the part 8 is attached to the hub 1, a projecting part of the part 8 is bent. Thus the pilot pressure is produced at the hub 1 and the disk 9 is automatically and simply positioned. Furthermore no eccentricity is produced when the coincidence is secured between the centroid of the disk 9 and the rotational center of the hub 1 in a loaded state of the disk 9.

Title: Film carrier tape
Inventor: NAKAMURA TAKU
IPC: H01L21/60
Filed: 1992-02-03
Abstract: PURPOSE:To prevent the title film carrier tape from becoming defective by electric short-circuit even in case of narrow pitch lead for multipin structure by a method wherein the lead on the suspender of a film carrier tape is formed in the groove or through hole provided on the suspender. CONSTITUTION:A groove 10 is formed by conducting an etching treatment on the suspender 8, which is the supporting frame of an insulating film, for the purpose of preventing the deformation of a lead 3 formed on the insulating film of a film carrier tape. A sheet of metal foil is adhered to the above- mentioned groove 10, and a metal lead wiring is formed. There is no limit in the depth of the groove 10, but the depth about same as the thickness of the metal foil is desirable. As a result, when a resin-sealing operation is conducted in transfer molding, the metal lead wiring on the suspender 8 is collapsed by closing the top and bottom forces, and the unsatisfactory state such as electric short-circuit and the like can be improved.

Title: Radiant ray detector
Inventor: IMAI TETSUO
IPC: H01L31/024
Filed: 1984-02-02
Abstract: PURPOSE:To reduce dimensions and save weight of the apparatus, eliminating use of liquefied nitrogen and facilitating maintenance, by keeping the inside container at lower temperature than the outside one with an electronic cooler applying the Peltier effect and raising cooling efficiency of a radiant ray detecting element. CONSTITUTION:As an inside container 31 is kept colder by approximately a few ten degrees than an outside container kept vacuum inside with outside electronic cooler 30 and inside electronic coolers 33a-33f applying the Peltier effect respectively, heat quantity transmitted to a radiant ray detecting element 35 becomes extremely limited. A pressurizing O-ring 32 improves thermal contact of the cooler 30 and the bottom plate 23 and as heat transfer from the plate 23 to the inside container 31 is prevented with the O-ring 32, cooling efficiency of the detecting element 35 is raised the more. Consequently, cooling by liquefied nitrogen becomes unnecessary and maintenance easier and the apparatus reduced in dimensions and lighter in weight.

Title: Steering angle detector
Inventor: FUKINO MASATO
IPC: G01B7/30
Filed: 1987-01-28
Abstract: PURPOSE:To allow a one-rotation potentiometer to function normally as a multirotation type by deciding whether or not a 1st current collection member contacts a resistor finely or not, and precluding the malfunction of steering angle arithmetic. CONSTITUTION:When a steering wheel 2 is rotated for steering, a shaft member rotates on a supporting member, and a ring-shaped resistor, the shaft member, and 1st and 2nd current collection members 60a and 60b fixed to the other side of the supporting member come into slide contact, so that the 1st and 2nd current collection members 60a and 60b outputs out-of-phase detection signals corresponding to the steering angle. Further, a fine contact state deciding means (arithmetic processor, etc.) positions the 1st current collection member 60a at the border part of the electric blind zone of the ring-shaped resistor according to the detection signals of the 1st and 2nd current collection members 60a and 60b and when it is decided that the member is in slight contact with the ring-shaped resistor, a steering angle correcting value arithmetic means (microcomputer) calculates the correcting value for a steering force according to the detection signal of the 2nd current collection member 60b.

Title: Clock signal disconnection detecting circuit
Inventor: KIRIYAMA YOSHIO
IPC: H03K5/19
Filed: 1988-01-27
Abstract: PURPOSE:To detect the disconnection of a clock signal by a carry signal from a counter circuit by allowing a counter circuit not generating a carry signal against a normal change of a clock signal to be monitored to count an output signal of the oscillation circuit and resetting the counter circuit through the use of a change in the clock signal. CONSTITUTION:While a clock signal 110 to be monitored is inputted normally, a reset signal 115 is generated for each change number of the clock signal 110. Thus, no carry signal 116 is outputted from the counter circuit 110. Then the clock signal 110 is fixed to '1' or '0' and the signal disconnection state is reached, then output signals 113, 114 of the sampling circuit of the same level are outputted from two D flip-flops in a sampling circuit 104, thus no reset signal 115 is generated. The counter circuit 103 continues the count to output a carry signal 116 finally. Thus, the carry signal 116 is used as a clock signal disconnection detection signal.

Title: Brake tester with abs inspection function
Inventor: OYAGI TAKASHI
IPC: G01M17/007
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain a brake tester whose costs can be lowered, whose space can be saved and whose economical efficiency can be enhanced by a method wherein a clutch mechanism is installed between a shaft at a rotating roller on the rear side and a power transmission mechanism. SOLUTION: A wheel 100 at a vehicle to be measured is placed between four rotary rollers 1, 2 so as to come into rotary contact. In the case of an ordinary brake test, a clutch mechanism 7 is coupled, a driving source 4 is driven, and the respective rotary rollers 1, 2 are turned via a power transmission mechanism 3. When a driver on the vehicle to be measured applies a brake, a braking force is detected by a detector 5, and the performance of the brake can be judged. When an ABS function is inspected, the clutch mechanism 7 is set to an uncoupled state, and only the rotary rollers 1 on the front side are turned.  When a brake is applied in this state, the ABS function is operated, a braking force is weakened once when the wheel 100 is brought close to a locked state, the braking force is strengthened again when the rotational speed of the wheel 100 is restored, and the rotational speed is increased and decreased repeatedly. When the rotational speed at this time is detected by a rotational-speed detector 6, it is possible to judge whether the ABS function is operated or not.
