Patent JP-H0851001-A (JP)
Title: Ceramic resistor
Inventor: AIDA HIROSHI
IPC: H01C7/00
Filed: 1994-08-09
Abstract: PURPOSE:To obtain a ceramic resistor in which the volume resistivity is set lower than a predetermined value without sacrifice of the characteristics, e.g. corrosion resistance, of aluminum nitride by controlling the quantity of oxygen and the lattice constant thereof. CONSTITUTION:An insulator principally comprising aluminum nitride contains 0.005-20atm% of oxygen in the crystal of aluminum nitride. The oxygen is an essential element for imparting the conductivity to aluminum nitride. When the quantity of oxygen is insufficient, a desired resistance can not be obtained and when the content of oxygen exceeds 20atm%, the control of resistance becomes difficult. The volume resistivity of an insulation layer can be regulated within 10<14>OMEGA-cm by controlling the lattice constant of aluminum nitride in the range of 3.105-3.117Angstrom  for a-axis and in the range of 4.973-4.990Angstrom  for c-axis. This resistor exhibits excellent stability of resistance where the variation of resistance in the temperature range from room temperature to 400 deg.C is within three figures of the resistance at 25 deg.C.

Title: Ferromagnetic thin film filter
Inventor: ITO SEIGO
IPC: H01P7/00
Filed: 1984-09-06
Abstract: PURPOSE:To obtain a filter with high mass-productivity and less variance in the characteristic whose resonance frequency is varied linearly over a broad band by positioning a ferromagnetic thin film to a position of a nearly odd number of multiple of 1/4 signal propagating wavelength of the pass band from each open end of an input/output strip line. CONSTITUTION:The length of open ends 13A, 14A and 18A, 18B of strip lines 13, 14, 18 from the center of circular YIG thin films 15, 16 is selected respectively to a nearly odd number of multiple of 1/4 of a propagated wavelength lambdaof the pass band signal. In supplying a high frequency signal having a propagation wavelength lambda to the input strip line 13, the high frequency signal is propagated to the open end 13A and since the length of the open end 13A is set as stated above, the state of maximum voltage, minimum current (zero), minimum magnetic field (zero) is attained at the open end and the state of minimum voltage (zero), maximum current, maximum magnetic field is attained conversely at the center of the YIG thin film 15. Thus, when a frequency (f) is isolated, a filter using the (f) as the band center frequency is obtained.

Abstract: PURPOSE:To improve the environment in a factory and to reduce equipment cost by providing a tunnel having open parts at the front and rear to a line for the post treatment of casting molds and disposing an intake port for a discharge fan to the inside of the tunnel. CONSTITUTION:The open parts 3a are provided to the front and rear of the tunnel 3 enclosing the post treating stage line 2 for the casting molds and air curtains 5 are disposed to the inlet and outlet thereof.

Knockedout upper and lower molds W are oscillated on an oscillating table 8 to transfer the molding sand and castings to a discharge conveyor 9. The molds W are transferred on the line 2. The molds W are cooled by cooling fluid and since the heat, smoke, dust, etc. generated in the line 2 are shut off by the air sucked by the fan 4, the environment in the factory is improved. The smaller capacity of the discharge fan is required and therefore the equipment and running costs are reduced.

Title: Dynamic programming collating device
Inventor: YAMAZAKI YASUSHI
IPC: G10L15/28
Filed: 1991-07-26
Abstract: PURPOSE:To effectively use the memory which stores candidates and to prevent the lowering of collating performance of a dynamic programming collating device which is used to perform voice recognition that executes DP path pruning in accordance with a certain threshold. CONSTITUTION:In the dynamic programming collating device which compares the accumulated distance at each time and the threshold during the execution of a DP collation and limits the DP paths after that, a monitoring section 15 monitors the number of the remaining DP paths at each time of the input and threshold change section 16 changes the threshold. When the candidate number of DP paths becomes too large, the memory capacity is saved by making the threshold large and reducing the number of candidates. On the other hand, if the candidate number of DP paths becomes too small, the collating performance is improved by making the threshold small and increasing the number of candidates.
