Title: Powder molding machine
Inventor: SHIGEMATSU KAZUICHI
IPC: B30B11/18
Filed: 1989-01-18
Abstract: PURPOSE:To increase output and to allow silent and stable operations to be carried out by providing a prepressing roll facing one molding roll of a pair of molding rolls. CONSTITUTION:The stationary molding roll 1 and the prepressing roll 3 bite in and compress raw material powder 5 when the raw material powder is supplied into a hopper 4 provided to cover both these rolls. Since the raw material powder 5 is supplied by its own weight alone, the air separated at the time of compression can be easily escaped to above the hopper 4. Since the powder receives the locally large compressing force by the prepressing, the prepressurized powder 6 which includes the partly molded small lumps and have a large bulk sp. gr. and good air permeability is obtd. Since the bulk sp. gr. is large, the plate molding having a large thickness is obtd. when such powder is supplied to the stationary molding roll 1 and the press molding roll 2. The increase of the rotation speed is possible as the air permeability is good. The output is thus increased.

Title: Optical information recording and reproducing device
Inventor: OTA KAZUHIKO
IPC: G11B7/09
Filed: 1988-01-18
Abstract: PURPOSE:To prevent a tracking error signal from being disturbed and to correctly position an optical spot by detecting a defect on a tracking spot. CONSTITUTION:A difference between the maximum value Y2 of respective amplitude values of a reading signal for two tracking spots 104, 105 and a maximum values Y1 of respective amplitude values of a reading signal 102 for two preceding tracking spots 100, 101 is found out. When the difference is not included within an allowable range, the existence of a defect on the tracking spot 105 is decided and the reading signal 102 of the tracking spot 105 is inhibited to be used for the calculation of the tracking error signal. Even if a defect exists in the tracking spot, an optical spot can be correctly positioned without almost being disturbed.

Title: Self-excited oscillation power supply circuit
Inventor: AKKER JOUW VAN DEN
IPC: H02M3/338
Filed: 1986-01-20
Abstract: For energizing a load (10) with different input voltages, the circuit comprises a transformer (6), whose primary winding (n1), in series with the collector-emitter path of a switching transistor (T1), the load (10), and a current sensing resistor (R2), is arranged between the input-voltage terminals. The seccondary winding (n2), in series with a diode (D1), is arranged in parallel with the load (10). When the input voltage is applied a very small base current is fed to the switching transistor (T1) via the starting resistor (R1), which results in a small current in the primary winding. The resulting voltage rise across the secondary winding (n2) ensures that the switching transistor (T1) is bottomed rapidly via a positive-feedback loop, which comprises the series arrangement of a first resistor (R4), a capacitor (C1) and a second resistor (R5) and which is arranged between that end of the secondary winding (n2) which is connected to the diode (D1) and the base of the switching transistor (T1). For a specific current in the primary winding (n2) the switching transistor (T1) is turned off by means of a control transistor (T2), whose base is connected to the current-sen sing resistor (R2). The energy stored in the transformer (6) is then delivered to the load (10) by an output current in the secondary winding (n2). In order to prevent this output current from increasing strongly at increasing input voltages as a result of the increasing saturation of the switching transistor (T1) via the positive feedback, a zener diode (Z1) is arranged between the junction point of the capacitor (C1) and the resistor (R5) and the base of the switching transistor (T1). Above a specific input voltage this zener diode (Z1) is turned on and drains the base supply current to the emitter of the switching transistor.

Title: Optical radar device
Inventor: TAMIYA NORIHIRO
IPC: G01S17/88
Filed: 1986-01-16
Abstract: PURPOSE:To improve an SN ratio by demodulating a low frequency signal by a sampling means which use sampling pulses in alarm range phase and detecting whether or not there is a target according to whether or not the low frequency is present. CONSTITUTION:A received pulse signal F is sampled and held 10. A clock pulse A, on the other hand, is delayed by the quantity of delay in an alarm range which s set 6 through a variable delay circuit 14 to become a signal D, which is passed through s sample pulse width setting circuit 15 to obtain sample pulses E. When the timing of the pulses E is within a period where there is the signal F present, a low frequency signal G is demodulated and amplified by a low frequency amplifier 11 to a necessary level. The output signal H of the amplifier 11 is detected 12 and the detection output I is compared with a constant threshold level by a target in an alarm range. The majority of the reception amplification factor of this optical radar device is loaded on the amplifier 11 and the pass-band width of a noise is narrowed down for an arrival signal, so the SN ratio is improved.
