Title: Oscillation circuit
Inventor: NAKAMOTO HIROYUKI
IPC: H01S5/00
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To stably obtain a driving signal for driving a laser diode. SOLUTION: An oscillation output signal from an oscillator 1 is applied to a laser diode LD after being amplified by an output amplifier 2. The laser diode LD is turned 'on' at every high frequency. Since laser beam is emitted by multi-mode at rise of a laser diode, laser beam is continuously emitted by multi-mode. Since the output amplifier 2 is operated in a boundary between a linear region and a saturation region, dispersion of output signal can be restrained.

Title: Plastic frame of spectacles
Inventor: YAMADA YORINOBU
IPC: B29D12/00
Filed: 1986-01-28
Abstract: PURPOSE:To prevent a plastic frame from fading by a method wherein a base consisting of epoxy resin, the surface of which is colored by dye and then adsorbed by polar substance with specified dielectric constant, is covered with polyurethane resin containing stabilizer. CONSTITUTION:The fading in epoxy resin dyed by dye proceeds in radical mechanism. Consequently, when the periphery of the dye is put in ionic atmosphere by utilizing non-protonic polar substance the dielectric constant of which is 23 or more, preferably 36 or more, the fading becomes practically negligible. In addition, when the polar substance is used in combination with polyurethane coat, in which anti-oxidizing agent, surface-active agent together with ultraviolet absorbing agent are mixed, the resultant anti-fading effect becomes nearly perfect.

Title: Subscriber interface network
Inventor: MUNEDA YASUSHI
IPC: H04Q3/42
Filed: 1989-01-27
Abstract: PURPOSE:To improve the working rate of a private switched network by equipping a subscriber interface network with a protocol converter to convert or inversely convert an incoming call received in the subscriber interface for an ISDN interface. CONSTITUTION:A protocol converter 31 sends a second dial tone for a subscriber 41. The subscriber 41 confirms the dial tone and after that dials the address of a subscriber 42 at an incoming side. A private ISDN exchange 21 analyzes the address of the subscriber 42, executes starting, confirming, and address sending operations between exchanges 21-23 by an ISDN interface 53, and establishes a speech path up to a protocol converter 32. At this time, the device 32 sends a seizing signal for a public telephone exchange 15, and the exchange 15 executes a calling operation under an ordinary interface form and sends a starting ringing tone for the subscriber 42. Therefore, when the subscriber 42 makes a receiver into an off-hook state, a call can be executed. Thus, the working rate of the private switched network can be improved, and a communication charge can be reduced.
