Title: Waveguide type optical module
Inventor: TAKASUGI SATORU
IPC: G02B6/42
Filed: 1992-09-07
Abstract: PURPOSE:To decrease the axial misalignment quantity between a waveguide device and other part at the time of packaging and to improve temp. characteristics by forming a relief part for deformation on the mount of the waveguide device. CONSTITUTION:The waveguide device 1 of a quartz system is packaged within a structural body (casing) 6 in the state of being aligned together with a light source 6, such as semiconductor laser, by lenses 8, 9. The waveguide device 1 and its mount 3 are soldered to each other. For example, a nickel alloy is used as the material of the mount 3. On the mount 3, a slit 4 is formed horizontally along the longitudinal direction from the end face on the side opposite to the light source 5. The length of the slit 4 is about 2/3 the length of the mount 3. The slit 4 constitutes the relief part. As a result, even if warpage is generated between the waveguide device 1 and the mount 3 by the thermal deformation arising from a difference in coefft. of thermal expansion, the warpage is absorbed within the slit 4 and is, therefore, not transmitted to the structural part 6.

Filed: 1990-09-07
Abstract: PURPOSE:To reduce a thermal offtrack amount and to prevent the read error of data by interposing an elastic magnetic substance between a yoke and a permanent magnet. CONSTITUTION:A permanent magnet 6 is respectively held through an elastic magnetic substance 7 to a yoke 5, and the yoke 5 is similarly held through the elastic magnetic substance 7 to spare base plates 3 and 4. This elastic magnetic substance 7 forms the magnetic circuit for compensating a magnetic gap between the permanent magnet 6 and the yoke 5. Assuming that a bimetal state is generated according to the difference between the linear expansion coefficients of the permanent magnet 6 and the yoke 5 by the temperature increase or environmental temperature change of the device to generate thermal striction or that the bimetal state is generated by the difference between the linear expansion coefficients of the yoke 5 and the spare base plates 3-4 so as to generate thermal striction, this thermal striction is absorbed by the elastic magnetic substance 7. Thus, there is no thermal offtrack amount and the read error of data is prevented.

Title: Heat-resistant extruded foam and its manufacture
Inventor: HAYASHI HISATAKA
IPC: C08L77/00
Filed: 1989-09-14
Abstract: PURPOSE:To manufacture easily a high-magnification foam having a microscopic and uniform bubbles, by a method wherein extrusion foaming is performed by making use of a pellet obtained by kneading polyphenylene ether and polystyrene. CONSTITUTION:After kneading of a pellet obtained by kneading 40-90 pts.wt. polyphenylene ether and 60-110 pts.wt. polystyrene with an extruding machine and a foaming agent under a high temperature and high pressure, the same is extruded in a low-pressure zone. In this instance, when the polyphenylene either is less than 40 pts.wt., it is not only that heat resistance becomes insufficient but also that in the case where both are made into the pellets by kneading them, the pellets become cloudy due to insufficient melting of the polyphenylene ether and when extrusion foaming is performed by making use of the pellet, bubble irregularity is generated within a foam. On the one hand, when the polyphenylene either exceeds 90 pts.wt., gelation can not be performed by an ordinary extruding machine due to an insufficient temperature rise or overloading and pelleting becomes very hard.

Filed: 1989-09-18
Abstract: PURPOSE:To extract a maximum signal level stably with high accuracy and to improve the adjustment accuracy by varying a gain of a level control section corresponding to an output signal level of an object to be adjusted so as to make an input signal level to a level extraction section constant. CONSTITUTION:When a device changeover switch 30 of an operation section 2 is depressed and a command signal 75 is inputted, a control section 3 generates a gain data 72 so that an input signal 71 of a level extraction section 5 reaches an unsaturated level to set a level control section 4. The control section 4 uses the gain to amplify and attenuate an output signal 70 of an adjusted object 60 with the gain and gives an output to the extraction section 5. The extraction section 5 receives the analog signal 71 to extract the maximum signal level VS of specific parts A, B and it is converted into a digital signal 73. The control section 3 reads the signal 73 to obtain the direction of adjustment and outputs a control signal 74 to a mechanism section 6 to control the operation of the mechanism section 6 turned in fitting with the adjustment part 61 of the object 60. Then the data 72 is newly generated and the new data 72 is used for readjustment. Thus, the input level of the extraction section 5 is made constant.
