Title: Controller of motor
Inventor: ITOU YUTAKA
IPC: H02P3/24
Filed: 1983-07-15
Abstract: PURPOSE:To preferably brake via DC a motor by detecting the current flowed to the motor, and limiting the current so as not to exceed the prescribed value when the current reaches the prescribed value lower than the current for operating an inverter protecting unit. CONSTITUTION:When the output voltage of an operational amplifier 2 becomes negative, the output of an operational amplifier 4 is inverted, an integrating capacitor C3 is charged, and the output voltage of the amplifier 4 is raised. A negative voltage is outputted from a NOT element at the time when it becomes slightly positive voltage over zero voltage, a signal of a chopper controller CS outputted from an AND element A is stopped, a transistor Tr is interrupted, and a current is stopped by an inverter I. Accordingly, a motor M which is rotating at a low speed is stopped by a DC current limited for the prescribed time.

Title: Bit error rate measuring method
Inventor: KUWATA NAOKI
IPC: G11B20/18
Filed: 1989-05-23
Abstract: PURPOSE:To accurately evaluate an optical recording medium including an effect due to the pattern of a recording signal by recording and inspecting the signal equivalent to the signal recorded on the optical recording medium at an actually working state. CONSTITUTION:A recording operation is performed by setting a readout start address of a pattern ROM 107 with a controller 113. The recording signal 111 outputted from the ROM 107 is recorded on the optical recording medium 101. Next, the inspection of a bit error is performed by setting the readout start address of the ROM 107 for inspection with the controller 113. Part of code data read out from the medium 101 and outputted from a data discriminator 105 is inputted to a mark detector 109, and a SYNC mark is detected at the detector. Reproducing data is compared with data in the ROM 107 setting the detection of the mark as a trigger, and the data for which noncoincidence is obtained is counted with an error counter 110 as an error. Thus, a bit error rate can be obtained by dividing the counted number of errors by the amount of data to be inspected.

Inventor: NAKAMURA SADAAKI
IPC: E02B17/04
Filed: 1982-07-26
Abstract: PURPOSE:To attach a deck to a stationary offshore platform without the use of a crane ship by a method in which a strut is projected from a floating body consisting of a deck and a lower hull to give a buoyancy, and the strut is coupled with a coupler at the upper end of a jacket.

Title: Automatic focusing device
Inventor: KITO ISAO
IPC: G02B7/32
Filed: 1988-05-30
Abstract: PURPOSE:To obtain a focusing state which is invariably accurate within the entire temperature range of practical use and free from an error by correcting measured distance information so that the state of focusing decision making does not change irrelevantly to temperature variation. CONSTITUTION:A two-division photodetection part equipped with, for example, two photodetectors 1 and 2 is used as a 1st detecting means which measures the distance to an object. Then the output of one photodetector 1 is corrected with variation in the resistance of, for example, a heat sensing resistance 4 as a 2nd detecting means with temperature and the measured distance information obtained by the two photodetectors 1 and 2 is corrected into information at set reference temperature. In another way, temperature information detected by the 2nd detecting means 4 is contrasted with the quantity of measured distance deviation corresponding to case-studied temperature variation to correct the measured distance information into information at the set reference temperature. Consequently, the invariably correct focusing state is obtained irrelevantly to the expansion and contraction of distance measurement part constituent components due to temperature variation.
