Title: Optical module
Inventor: SHIRAI MASATAKA
IPC: G02B6/42
Filed: 2001-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce module power consumption of a modulator integrated laser. SOLUTION: High level of reliability and optical output is sustained even if an element is kept at a high temperature by composing a multiple quantum well constituting a laser active layer region of InGaAlAs/InGaAlAs. Difference between the oscillation wavelength and the band gap wavelength of a modulator and a laser must be set larger by an amount proportional to a set temperature rise of the element in order to sustain the transmission characteristics. Since the difference between module case temperature and set temperature of the element is decreased, module power consumption can be reduced.

Title: Door catching detector for vehicle
Inventor: FURUYA MAKOTO
IPC: B60J5/00
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a door holding device for a vehicle capable of preventing door catching from being erroneously detected when a door is re-opened. SOLUTION: A body side microcomputer sets a door catching determination value P3 based on a minimum pressure value P2 when a door 2 is closed from an open position, and detects the presence or absence of the door catching by comparing an opening and closing pressure P2' when the door 2 is closed from the open position with the door catching determination value P3. In this case, when a door tip rubber is cracked, the opening and closing pressure P2' becomes negative when the door is opened again, but not used for the renewal of the minimum opening and closing pressure P2. Accordingly, since the door catching determination value P3 is not set to an abnormally small value based on an abnormal minimum pressure, an erroneous detection of the door catching can be prevented.
