Title: Measuring method for number of particles attached to product and storing device for said method
Inventor: KAJIMA TOMOAKI
IPC: G06M11/00
Filed: 1987-05-26
Abstract: PURPOSE:To decrease the number of particles attached to products within a product working room excluding the particles due to exposure, by forming an opening on the upper surface of a product carrier and transporting the products horizontally at all times between an inspector and the product working room. CONSTITUTION:A wafer carrier 6 has an increased opening area and therefore a wafer 1 can be exposed into a clean room 7 while the wafer 1 is kept in the carrier 6. Thus a pincette operation which is required for a transfer job of the wafer 1 can be omitted. As a result, the number of particles attached onto the surface of the wafer 1 is decreased. Furthermore, the wafer 1 is always carried horizontally between an inspector 2 and the room 7. Therefore the number of touches/collisions between the wafer 1 and the carrier 6 is extremely decreased. Thus no defect nor crack occurs substantially on the wafer 1 and no particle is attached to the wafer 1 while it is carried.

Filed: 1983-07-15
Abstract: PURPOSE:To improve the minimum measuring level of incident light power and to obtain a wide dynamic range by impressing reverse bias voltage which is zero or minute at a region having small incident light power and large at a region having large power to a photo diode. CONSTITUTION:When the incident light is given to the photo diode 1, a light detecting current I0 flows, a voltage VL corresponding to the current I0 is generated across a load resistance RL and a positive output voltage V0 corresponding thereto is obtained. The output voltage V0 is inputted also to a voltage generating circuit 5 for reverse bias and an output voltage V1 for reverse bias is obtained at the output terminal of an operational amplifier 6 for reverse bias but the diode 8 is kept turned off until the output voltage V0 rises to a prescribed value. Thus, the output voltage V1 is kept nearly zero and the reverse bias voltage of the photo diode 1 is kept also nearly zero. The forward series resistance value of the diode 8 is decreased with the increase in the incident light power, the output voltage V1 is increased and the reverse bias of the photo diode 1 is made deep.

Title: Coded-signal decoding apparatus
Inventor: EMA NORIYUKI
IPC: G11B20/10
Filed: 1993-05-31
Abstract: PURPOSE:To realize a coded-signal decoding apparatus, which can perform the lead-in of synchronization quickly again without erroneous decoding when frames becomes discontinuous in editing and the like. CONSTITUTION:The synchonization pattern of a coded signal is detected with a synchronization-pattern detecting part 2. The frame-length information is extracted from the coded signal S1 by a frame-information extracting part 3. Two judging-timing generating parts predict the next synchronizing position based on the frame-length information. Two synchronized-state judging parts judge the synchronized state and output the synchronized state information. A state-transition control part 7 selects either of two timing generating parts based on the outputs of two synchronized-state judging parts and outputs the synchronized state information. A decoding part 8 performs decoding by utilizing the synchronized state information. Thus, either of two judging-timing ocurrences is selected by the state-transition control part 7. In this way, synchronization deviation caused by synchronization missing is protected, the lead-in of the synchronization of the discontinuous coded signal is made to be the high-speed operation and noise generation at the discontinuous point can be avoided.

Title: Optical switch
Inventor: KINOSHITA OSAMU
IPC: G02B26/08
Filed: 1982-07-28
Abstract: PURPOSE:To eliminate the need for a timer, etc., and to simplify a driving circuit by utilizing the displacement of a movable piece for optical path switching, and controlling the driving current of an electromagnet which moves the movable piece. CONSTITUTION:While an electromagnetic coil 8 is off, an optical path is formed between optical fibers 1 and 2 and a switch 12 is closed to short-circuit a resistor 13. When a voltage is applied between terminals 9 and 10, the driving current flows to the electromagnetic coil 8 of the electromagnet through the switch 12 and a magnetic body 7 is magnetized to attract the movable piece 4. Since the displacement of the movable piece 4 is transmitted to the switch 12 through an elastic body 11, so the switch 12 is opened with delay and the driving current flows through a resistor 13. The movement of the movable body 4 changes the optical path between the fibers 1 and 2 to that between the optical fibers 1 and 3. Consequently, the need for the timer, etc., is eliminated and the driving circuit is simplified.

Filed: 1980-09-22
Abstract: The method for creating an environmental seal for the end of a severed multiconductor cable and for sealing the joints between the conductors of such cable with the contacts of a multiple contact connector into which such cable is inserted. A tape of a soft, pliant material is coated on both sides with a flowable, pressure-sensitive adhesive and is formed into a blank which can be adhered to the cable in various ways. In a first form, the blank encompasses the severed end and portions of the cable adjacent the end. When the connector into which the cable has been inserted is compressed, the adhesive is displaced to seal the contact-conductor joints. Folded-over end flaps seal the cable ends. A midspan use of the blank permits the joints to be sealed without reference to the cable end.
