Title: Semiconductor laser device
Inventor: NANBARA SEIJI
IPC: G11B7/125
Filed: 1990-10-09
Abstract: PURPOSE:To decrease the ratio of a natural illumination component and an error at time of reading by using a front light of a semiconductor laser at time of data writing and using a rear light of the semiconductor laser at time of data reading. CONSTITUTION:In the case of write to an optical disk 6, a turning jig 4 is adjusted to allow a front light 2 of a semiconductor laser 1 to radiate the optical disk 6 so that the front light 2 irradiates the optical disk 6 via a polarized light beam splitter 5 and a lens system to write a data. Conversely in the case of read from the optical disk 6, the turning jig 4 is turned by 180 deg. so that a rear light 3 of the semiconductor laser 1 to irradiate the optical disk 6 and the data is read by using the rear light 3. Thus, the front light being a high output light of the semiconductor laser 1 is used and the rear light being a low output is used at time of reading so as to suppress the ratio of the natural illuminance light component included in the full light output thereby reducing the data read and the error in reading.

Title: Air blowing device for seat
Inventor: ANDO YORIAKI
IPC: A47C7/74
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain a comfortable feeling of sitting without deteriorating ventilation. SOLUTION: An air blowing device 1 for seat consists of a seat mat 2 which has air channels inside and a hose 3 connected to an air conditioner mounted in a car. The seat mat is made by connecting mat elements 7 and flexible tubes 8 alternately. There is a space formed between the tubes 8 and a seating face. When the user sits on the seat mat 2, the tubes 8 bend and the seat mat 2 deformes along the body of the user and therefore the user can obtain a comfortable feeling of seating. Since the body of the user is brought into contact mainly with the mat elements 7, load on the seat mat 2 is supported by the mat elements 7. Therefore, the tubes 8 are not destroyed and the air flow does not become stagnant. Furthermore, the mat elements 7 have sufficient strength and the air channels are not destroyed and there is no deterioration in ventilation.
