Title: Optical connector
Inventor: MASUO MASAHARU
IPC: G02B6/38
Filed: 2001-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical connector with a lock mechanism which has no play. SOLUTION: When an optical plug 10 is inserted into a receptacle 20, a slide member 14 is pressed into the receptacle 20. Simultaneously, an engagement projection 14d engages with a groove 11c and the ferrule 11 is also pressed into the receptacle 20. When the slide member 14 and ferrule 11 are inserted into the receptacle 20, a clock member 22 engages with engagement recessed parts 11b and 14f with the spring force of a leaf spring 24 to lock the optical plug 10. When the slide member 14 is drawn out, the locked state is released and the optical plug 10 comes out. When the optical connector is thus used, the slide member 14 slides on the tip-side outer circumference of the ferrule 11, a fiber fixation part 12, and a bushing 13 by a fixed distance, but a projection 13c provided on the side of the bushing 13 prevents the slide member 14 from playing.

Title: Semiconductor device
Inventor: SATO KATSUMI
IPC: H01L27/06
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the oscillation of a device voltage with a large amplitude while improving the relationship between the switching loss and the loss due to conduction in a semiconductor device having diodes or switching devices made of silicon carbide. SOLUTION: A resistor 12 is connected in parallel to a diode 11 made of silicon carbide. Although the resistance component of the diode 11 considerably varies as the diode 11 turns on and off, variation in the resistance component of an LCR circuit formed by the diode 11 and external wiring can be suppressed because the resistor 12 is connected in parallel to the diode 11. In this way, it is more unlikely that the LCR circuit satisfies the condition of a natural oscillation and simultaneously the increase in the quality factor of the LCR circuit can be suppressed.
