Abstract: PURPOSE:To improve the adaptability to a control mechanism and to widen a usage region, by together providing a slit and a pattern code in the peripheral direction of a rotary disc and properly using both of them corresponding to a high speed and a low speed. CONSTITUTION:In the high speed rotation region of a rotary disc 13, slits 15 of a large pitch capable of carrying out reading at the time of high speed rotation are detected to calculate the quantity of rotation at the time of a high speed. In a low speed rotation region, pattern codes 14 capable of accurately reading the angle of rotation even at any rotary position are detected to calculate the quantity of rotation at the time of a low speed. Therefore, the higher rank figure side of the output value corresponding to the quantity of rotation of the rotary disc 13 is allowed to correspond to the number of the pitches of the large pitch and the lower rank figure side thereof is allowed to correspond to the pattern codes 14 and, when the values respectively obtained are added, the quantity of rotation of the rotary disc 13 can be accurately calculated.

Title: Measurement system for underwater data
Inventor: WATANABE YASUNORI
IPC: G01S15/08
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To precisely position a sea surface-side ultrasonic transceiver onto a measuring instrument on the sea bottom without setting a marking buoy by utilizing the communication between the sea surface-side transceiver held by a marine vessel and the measuring instrument set on the sea bottom to guide the marine vessel. SOLUTION: Various hydrographic phenomena data are measured by a measuring instrument 1 using ultrasonic wave which is set on an intended sea bottom, transferred to a sea bottom-side ultrasonic transceiver 2 through a cable 2a, and accumulated in a memory part. When the measurement data is recovered, a marine vessel 5 loading a sea surface-side ultrasonic transceiver 3 is guided to the measuring instrument 1-set sea surface by GPS navigation, and the transceiver 3 is put into the sea. The transceiver 3 transmits a call signal from a measurement data recovering device 4, receives the response signal from the transceiver 2 after the lapse of a prescribed time, and calculates the required time from the transmission of the call signal to the receipt of the response signal to move the marine vessel 5 in the direction of reducing the required time.  The transceiver 3 can be thus approached just above the transceiver 2, or the measuring instrument 1.

Title: Dry etching apparatus
Inventor: SHIBAGAKI MASAHATA
IPC: C23F1/00
Filed: 1985-11-06
Abstract: PURPOSE:To uniformize a current density by increasing the impedance of a cover as compared with that of a substrate, and disposing the surfaces of the cover and the substrate substantially in the same plane. CONSTITUTION:A chamber 1 is evacuated by an evacuating system to a predetermined pressure, and CF4 gas is fed, for example, from a gas feeding system. A high frequency voltage is applied by a high frequency power source 11 between an anode 9 and a cathode 2 to generate a plasma 13 to dry etch a substrate 5. In this case, since an ion current by the plasma 13 is concentrated at the substrate 5 having small impedance, the ion current density flowing to the substrate 5 becomes high, and the etching rate becomes high. Since the surface 5a of the substrate 5 and the surface 23a of the cover 23 are disposed in the same plane, an electric field density becomes uniform in a boundary between the surfaces 5a and 23a, and does not become irregular on the surface of the substrate 5. Thus, ion current of uniform density flows on the surface 5a of the substrate 5 to uniformly etch the substrate 5.

Title: Abnormality detecting circuit for computer
Inventor: FURUKUBO YUJI
IPC: G06F11/30
Filed: 1987-10-01
Abstract: PURPOSE:To surely detect the abnormality of a computer by designating an address area to detect the illegal write based on the output signal received from a central arithmetic processor. CONSTITUTION:The abnormality of a computer 1 is detected by an illegal write detecting circuit 20 which can change the range of an illegal write detecting address in accordance with the program executing state of a CPU 10. In other words, the circuit 20 sets a computer abnormality signal 20a at 1 during a boot processing only when the CPU 10 has a write access to a ROM 11. Then the circuit 20 sets the signal 20a at 1 during an arithmetic processing when the CPU 10 has a write access to the ROM 11 or a code area 12a of a RAM 12. Thus it is possible to detect such abnormality of the computer 1 where a write access is given to the code area of the RAM 12. Then the probability is improved for the instantaneous detection of the occurrence of abnormality.
