Title: Packing method for semiconductor device
Inventor: NAKADA YUJI
IPC: B65B15/04
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To eliminate restrictions imposed on time from manufacture of semiconductor devices to packing the devices by tapes and time therefrom to the final packing thereof by a method wherein dehumidification for the semiconductor devices is executed by utilizing vacuum sucking. SOLUTION: Manufactured semiconductor devices are housed in packing materials and packed up by taping, and continuous taped and packed bodies are took up in a reel (step 1) and then the reeled-up package bodies are treated for 12 hours in a vacuum furnace at the room temperature at 5 Torr and thereby dehumidification is executed for the inside of the package bodies and the semiconductor devices (step 2), and the reeled-up products are sealed up and packed (step 3) and appropriately shipped (step 4). Since humidity is removed by vacuum sucking, there is no fear of applying thermal stress to the semiconductor devices while dehumidification is executed concurrently to the taping and packing materials.  Since vacuum dehumidification is executed at an appropriate time after the process of taping and packing, the degree of freedom for timing of processes from the taping and packing to the shipment is heightened.

CONSTITUTION:Since first and second coils 1a and 1b of a small conductor 1 which constitutes a superconducting coil are excited at low voltage independently by first and second exciting power sources 4a and 4b, the thickness of an insulator can be made small, and large current density can be realized, and by adjusting each exciting current an errorneous magnetic field by the winding errors of individual coils 1a and 1b is removed, and also since the outlet parts 2a and 2b of the first and second coils 1a and 1b are separated at an angle of 180 deg., a partial errorneous magnetic field can be made small. Moreover, it is possible to protect individual coils 1a and 1b from quenching phenomena peculiar to the superconducting coil. Accordingly, high magnetic field accuracy and large current density can be reconciled.

Title: Dc motor controller with encoder
Inventor: INAMURA JIYUNSHIROU
IPC: H02P7/288
Filed: 1984-02-20
Abstract: PURPOSE:To prevent a motor from running away by detecting the periodic change of a rotating direction detecting output and turning a motor OFF. CONSTITUTION:A detector 2 inputs 2-phase signals phiA, phiB outputted from an encoder 3 mounted on a DC motor 4, and outputs a rotating direction signal and a counted value. A controller 1 detects the rotating speed of the motor with the counted value to control the rotating speed of the motor to coincide with the speed command value, and confirms that the rotating direction of the motor coincides with the rotating direction command. On the other hand, when the rotating direction detection signal is varied periodically, it is judged that one phase of the 2-phase outputs of the encoder 2 is disconnected, thereby stopping the energization of the motor 4.

Title: Piston ring for internal-combustion engine and method for detecting abrasion thereof
Inventor: NAKAMURA YOICHI
IPC: F16J9/12
Filed: 1985-02-15
Abstract: PURPOSE:To make it possible to certainly detect the abrasion advance state of a coated piston ring, by imparting the stepwise abrasion marks of the coating layer of a piston ring to the lubricant supplied to the slide surfaces of the piston ring and a cylinder liner. CONSTITUTION:A coated piston ring 11 is constituted of a base material 11a, coating layers 11b, 11c comprising chromium plating and detection layers 11d, 11e. By depositing the second detection layer 11e to the base material 11a, the release of the coating layer 11c is prevented when the residual thickness of said coating layer 11c became thin because of abrasion and forecasting allowance is imparted when the coating layer 11c disappeared. When the piston ring 11 is mounted to a piston 11, elements constituting the abraded powder mixed in lubricant change with the elapse of time. This abraded powder is analyzed by a metal detector to detect the abrasion advance state of the piston ring 11. If the number of the coating layers of the piston ring and the depths thereof are preliminarily determined, the residual amounts of the coating layers can be estimated without cutting the piston ring.

Filed: 1980-03-07
Abstract: PURPOSE:To reduce displacement in a deflection position, by a method wherein an actual charging voltage of charged ink particles which bring a deflected orbit into a set deflection position is measured, and based on the measurements, the charge voltage is regulated. CONSTITUTION:Pressurized ink is fed to an ink nozzle, and is jetted as ink is vibrated to regularly separate it into ink particles. The ink particles are charged in a charging field, and is then deflected in a deflecting field to perform an ink jet recording. A charge voltage Vcs of the charged ink particles field in a set deflection position is detected, and a charge voltage Vci correspondig to each deflection position Xdi is found from setting the Vcs and a set deflection position Xds into correlation. With the charge voltage Vci applied to a charging electrode, a charging on the ink particles is conducted. Particularly, this is useful to prevent displacement in a deflection position in the case of multistage deflection in which several levels of chargings are conducted on ink particles jetted through a single ink nozzle.
