Title: Multi-layer injection molding method
Inventor: SEKI TAKEKUNI
IPC: B29C45/20
Filed: 1993-04-02
Abstract: PURPOSE:To obtain a container for housing a plurality of contents having different functions by a method wherein a resin for forming a container surface and a resin for forming a container intermediate layer are made to branch off from an injection device and they are induced to respective nozzles by slidingly move a valve so as to flow into a cavity. CONSTITUTION:A resin for surface layer and a resin for intermediate layer pass through hot runners 30, 40 respectively and flow to runners 31, 41 communicating with a main nozzle 1.0 and runners 32, 42 communicating with an auxiliary nozzle 20. When a valve 11 of the main nozzle 10 is made to recede, a passage 12 communicates with a central passage 15 and the resin for surface layer flows into a cavity 4. When the valve recedes further, a passage 14 communicates with the central passage so that the resin for surface layer flows into the cavity. When the valve recedes furthermore, a passage 13 is communicated and the resin for intermediate layer flows into the cavity. The resin for intermediate layer flows in between the resin for surface layer of the passages 12 and 14. Thereafter, when the valve 11 is made to proceed, the passages 13, 14, and 12 are closed in sequence. The auxiliary nozzle 20 has the same shape as that of the main nozzle 10 and operates in the same way.

Title: Resin molding device
Inventor: UCHIYAMA NORIHIRO
IPC: B29L31/34
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent bending of a lead due to foreign resin by roughing a mold surface for forming a pot and cull. SOLUTION: Colliding surfaces of molds 1, 4 for forming a pot 2 and a cull 5 are roughed to form roughed surfaces R. They are roughed so that uneven surfaces of, for example, about 1 to 5 μm are formed by a sandblasting method after colliding accuracy of previously mirror finished upper and lower molds 1, 4 is confirmed. When the molds are clamped and liquefied resin is fed from the cull 5 to a runner 7, it is introduced from an infinitesimal interval between the colliding surfaces of the molds formed with the roughed surfaces R into an uneven part of the roughed surface R, and proceeded to be cured in a short time. When this resin is cured, its adhesive properties are further enhanced. Therefore, even at the time of cleaning the mold by a mold cleaner 11, it endures against sliding by a rotary brush 12.  Thus, even if the mold is vibrated or impacted in the case of supplying next lead frame, bending of the lead can be prevented.

Title: Radio communication equipment
Inventor: OIKAWA HIROO
IPC: H04B1/50
Filed: 1994-04-15
Abstract: PURPOSE:To perform the communication with plural called stations on a single channel and with no cross modulation disturbance by providing a means which performs the transmission/reception switching to the frequency of one of paired waves of a duplex communication system and therefore securing the simultaneous reception of frequency of both waves. CONSTITUTION:A frequency converter means 6 receives the 1st frequency 440MHz of paired waves via a 1st high frequency amplifier means 4 and sends this frequency to a speaker 8 via an FM demodulator means 7. When a calling start switch 9 is turned on, a frequency converter means 13 converts the modulated signal received via a mike 10 into a 2nd frequency 420MHz of the paired waves via an FM modulator means 11 and sends this frequency via a power amplifier means 14. Under such conditions, the duplex communication is performed by the paired waves. When a transmission/reception switch 19 is turned on, a transmission/reception switching circuit 20 connects an antenna 3 to the means 6 via the means 4 for reception of the frequency 420MHz. Then the double transmission of the same frequency can be prevented since the communication is possible with other called stations.

IPC: H04B10/00
Filed: 1985-04-12
Abstract: PURPOSE:To obtain stable photo output, by installing a current-voltage conversion circuit and a peak value detecting circuit which detects the peak value of the output voltage of the conversion circuit, between the anode of semiconductor laser and the earth. CONSTITUTION:When the pulse signal voltage is not impressed, the current determined by the bias current controlling voltage flows through the semiconductor laser diode 3. The potential of one end point P of the resistor R4 descends, and the condenser C5 is charged by the current flowing through the diode D5, whose potential becomes equal to that of the point P. When the pulse signal voltage is impressed and becomes 'H', the potential of the point P descends furthermore, and the voltage of the condenser C5 also descends. When the pulse signal voltage turns to 'L', the potential of the point P ascends, and the diode D5 turns OFF. If the resistance value of R4 is sufficiently large, the voltage of the capacitor C5 is maintained, and the detected peak value is output form the terminal Q as the peak value. By selecting adequately the time constant C5R5, the peak value of laser current can be detected independently of the mark ratio of the pulse signal.
