Title: Chemical compound semiconductor logic circuit
Inventor: FUJII MASAHIRO
IPC: H03K19/0952
Filed: 1990-11-13
Abstract: PURPOSE:To eliminate the need for a special level conversion circuit by forming the logic circuit with plural enhancement FETs and one depletion FET so as to set a logic threshold level to a specific range. CONSTITUTION:A chemical semiconductor logic circuit consists of two enhancement FETs 1,2 and a depletion FET 3. The logic threshold level of the circuit is set between a minimum value of a high level specified by an ECL and a maximum value of a low level. When a high level signal being an ECL level is fed to a gate of the FETs 1,2, both the FETs 1,2 are turned on, a voltage at an output terminal 6 is increased by a source-drain voltage of the FETs 1,2 from a power supply voltage VSS. Moreover, when a low level is inputted to at least to one of input terminals 4,5, the FET receiving a low level in the FETs 1,2 is turned off and the voltage at the output terminal 6 rises up to VDD. Thus, the circuit connects to an IC employing an Si ECL circuit.

Title: Energy confinement-type piezoelectric vibrating gyroscope
Inventor: ABE HIROSHI
IPC: G01C19/5698
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric vibrating gyro which is small and whose accuracy is high, by forming an insulating film for mass addition only in a vibration region, which is situated on the main face of a piezoelectric plate and which is surrounded by a first electrode to a third electrode and is which an energy confinement vibration is generated. SOLUTION: A first electrode 11 is installed on the main face in the central part of a piezoelectric plate 10, and a second electrode 12 and a third electrode 13 are installed in such a way that they are parallel to the first electrode and that they are separated from the first electrode by a prescribed distance. AN insulating film 17 which is composed of, e.g. SiO, MgF, frit glass or the like is formed on a vibration region surrounded by the electrodes 11, 12, 13 is order to add mass to the vibration region. When a driving voltage is applied across the electrode 11 and the electrodes 12, 13, a vibration in the X-direction is excited, the piezoelectric plate 10 is turned around the Z-axis, a vibration due to the Coriolis force is generated in the Y-direction, and an electromotive force is generated across the electrode 12 and the electrode 13.  When the force is detected, a rotational angular velocity can be detected. Since the insulating film 17 exists in the vibration region, vibration energy is confined with a good efficiency, and a leakage vibration is reduced. Thereby, it is possible to obtain a piezoelectric vibrating gyro whose accuracy is high.

IPC: G01N1/04
Filed: 1987-12-08
Abstract: PURPOSE:To obtain a uniform representative sample from the product of the center part of a batch by providing a gate on the bottom part of a trough of a chain conveyor. CONSTITUTION:In order to obtain an intermediate part of a batch with respect to a product which is being carried by a horizontal chain conveyor 1, for instance, when 45sec are lapsed with respect to a product flowing through the chain conveyor 1 for 90sec, a gate 2 is opened earlier than the speed of a chain of the chain conveyor 1. As a result, the product flowing right above the gate 2 is all contained in a case 3 regardless of the upper layer, the middle layer and the lower layer. The gate 2 is closed after several seconds and returned to its original state. When the capacity of the case 3 is set in advance so as to become 1/100 of one batch, a collected sample comes to correspond to 1% of the product. Subsequently, when the gate 4 of the bottom part of the case 3 is opened instantaneously in <=0.5sec, the sample flows down as one lump in a chute 5 and no separating phenomenon occurs. In such a way, a uniform representative sample can be obtained from the product of the center part of the batch.
