Title: Nozzle device for extruding composite synthetic resin
Inventor: KAWAGUCHI KIYOSHI
IPC: B29C48/49
Filed: 1988-01-30
Abstract: PURPOSE:To enable the occurrence of stringing phenomenon to be remarkably suppressed or avoided by a method in which the synthetic resin flowing in an auxiliary extruding flow path and extruded in a main extruding flow path from an auxiliary extruding port, collides with the tip of the subextruding port-opening and closing member in a closed position, and scraps off the synthetic resin remaining there effectively. CONSTITUTION:Main synthetic resin R1 is caused to flow continuously to a main extruding port 44 in a main extruding flow path 42, and then auxiliary synthetic resin R2 is caused to flow continuously in an auxiliary extruding flow path 68 and to flow continuously into the main synthetic resin R1 in the main extruding flow path 42 from an auxiliary extruding port 66. On one hand, a subextruding port 90 is intermittently opened by an opening and closing member 74. The subsynthetic resin R3 flowing in a subextruding flow path 88 is caused to flow intermittently into the auxiliary synthetic resin R2 in the auxiliary extruding flow path 68 from the subextruding port 90. Thus, the composite synthetic resin having the form in which the synthetic resin R3 existing intermittently at every prescribed amount is surrounded with the auxiliary synthetic resin R2 and the main synthetic resin R1 existing continuously, is continuously extruded from the main extruding port 44.

Title: Automatic focus indicator of camera
Inventor: AOOI HARUMI
IPC: G02B7/36
Filed: 1979-02-19
Abstract: PURPOSE: To obtain the compact and inexpensive focus indicator by generating the focusing signal near the focus matching position by using a device which detects the single contrast signal from the subject image and a device which detects the extension direction of a lens.  
     CONSTITUTION: When the lens is extended, a peak holding level is reset and at the same time a coincidence gate closes, causing peak holding operation to start. When the contrast signal passes the peak, the extension direction of the lens is detected at that time, by which the peak is regarded true peak 11 and is processed only when it is not inverted. When the true peak is detected, the peak holding operation stops and the peak level is held. At the same time, the coincidence gate opens and the peak holding level Vpd and contrast signal Vc shown by the alternate long and short dash line are compared and when they become Vpd>Vc, it is near the focus matching position and the coincidence signal is emitted. In this way, the compact and inexpensive focus indicator is obtained.

Filed: 1994-01-20
Abstract: PURPOSE:To suppress a change of a loop gain due to a temperature change and obtain a stable control loop by providing a temperature-detecting means such as a temperature sensor or the like in the vicinity of an actuator as an element of a control loop system. CONSTITUTION:A temperature sensor such as a thermistor 21 or the like for measuring temperatures of an actuator 4 is set in the vicinity of the actuator 4. Temperatures of the actuator 4 during the operation are measured by the sensor. An output from the thermistor 21 is input to a controller 10 through a detection amplifier 22 and a second A/D converter 23. The controller 10 measures the output from the thermistor 21 every predetermined time, and applies a pulse signal B via a D/A converter 11 when detecting that a value of the thermistor 21 exceeds a predetermined temperature, so that a servo loop gain is adjusted. Accordingly, since a change of the servo loop gain resulting from a temperature change is restricted in the optical disc drive, the servo control is properly carried out.

Title: Charge transfer device
Inventor: MUTO HIDEKI
IPC: H01L29/772
Filed: 1986-02-01
Abstract: PURPOSE:To facilitate the setting of impurity concentration by impressing clock pulses on gate electrodes of two phases to transfer electric charges. CONSTITUTION:An insulating layer 8 of SiO2 is formed on the top of a p-type regions 6 in a region I and on the tops of n-type regions 4 in regions II and III, and electrodes 10 and 12 are formed on the top of the insulating layer 8 in the regions II and III respectively. The electrodes 10 and 12 are formed of polysilicon, used as gate electrodes for impressing clock pulses for electric charge transfer, and connected to clock pulse sources phi1 and phi2. Since clock pulses are impressed on the gate electrodes 10 and 12 of two phases to transfer electric charges, the impurity concentration in the regions II and III under the gate electrodes 10 and 12 is not necessarily made to differ, in contrast with a device in which a lock pulse is impressed on a gate electrode of single phase to transfer charges. By this constitution, the setting of impurity concentration is facilitated.

Title: Exhaust circulation control
Inventor: SUZUKI MIKIO
IPC: F02M25/06
Filed: 1978-02-22
Abstract: PURPOSE: To reduce NOx even in acceleration of an engine by ristricting reduction in suction negative pressure in acceleration to be fed through a circulation control valve and keeping a circulation control valve open to continue exhaust circulation for a certain period.  
     CONSTITUTION: As a throttle valve 21 is fully opened in acceleration of an engine, suction negative pressure downs suddently and the pressure near the fully open throttle valve goes down below the rising negative pressure of a circulation control valve 2. Once negative pressure switch 29 is turned on due to the variation in suction negative pressure, a solenoid valve 26 is closed. IN result, suction negative pressure having been fed into a negative pressure 16 of the valve before acceleration on is remained in it and gradually released through a delay valve 28 of a bypass 27. The circulation control valve 2 keeps the open state for a certain period which has been done before acceleration and allows circulation exhaust in acceleration to be supplied in an engine through the passage 3 at a circulation ratio amounting to that before acceleration.
