Patent JP-H01238184-A (JP)
Title: Buried semiconductor laser
Inventor: SUGAO SHIGEO
IPC: H01S5/02
Filed: 1988-03-18
Abstract: PURPOSE:To reduce a leakage current in a current block layer, to decrease a parasitic capacity, to perform a low threshold value and a high speed operation, and to obtain a high manufacturing yield by employing a semiconductor layer having a P-type conductivity type between an active layer and a semiinsulating substrate. CONSTITUTION:When a semi-insulating semiconductor layer 18 is formed, a p-n junction is formed between an n-type low resistance semiconductor layer 19 generated from the face A (111) of a double hetero structure and a p-type buffer layer 11 on a semi-insulating semiconductor substrate 10a. Since this junction is formed on an InP layer having a larger forbidden band with than that of the junction in a double hetero structure, the current flowing to the former junction is sufficiently smaller than that flowing to the latter junction by the same applying voltage due to the difference of built-in potentials. As a result, the injected current flows only to an active layer, a leakage current is remarkably reduced as compared with that of a conventional one, and a low threshold value of approx. 10mA is obtained with good reproducibility. The parasitic capacity is reduced by a semi-insulating semiconductor layer 18, and a modulation band of 10GHz or more is obtained.

IPC: B32B15/08
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To obtain an adhesive which can give a metal-clad laminate improved in electrical insulating properties by using an acid catalyst in the acetalization step in a process for producing the same.

In operating of the brake, an on-time counter is operated so as to be incremented (step S6), at the same time, a target fluid pressure is calculated (step 10), and a fluid pressure path opening/closing valve and a fluid pressure control valve are driven (step S11). On the other hand, the on-time counted by the on-time counter and a preset time are compared (step 7) and, when it is the preset time or more, the fail-safe valve is opened (step S9). This constitution can send the brake fluid pressure to the wheel cylinder after stabilizing the spool.

Title: Phase change recording medium
Inventor: ICHIHARA KATSUTARO
IPC: G11B7/2437
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To directly form a crystal space in an as-deposited amorphous state by an actual drive at a high speed without particularly carrying out initialization by providing a substantially amorphous state and a specified heat conductivity to the address part of a recording layer causing a prescribed phase change. SOLUTION: The recording layer of an optical recording medium has an address part and a data part. The data part has a substantially amorphous state in the unrecorded state before recording data and the heat conductivity is 0.8-6 W/mK. Since the recording medium is not passed through an initial crystallizing step, a header part and the data part are in the substantially amorphous state. The heat conductivity of the as-deposited amorphous part can further and widely be lowered by adjusting conditions in the formation of the recording layer and conditions in the formation of interference films on the top and bottom of the recording layer.
