Title: Semiconductor laser element
Inventor: YASUHARA NOZOMI
IPC: H01S5/12
Filed: 2009-01-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a high performance semiconductor laser by improving differential gain also while making increase of number (N<SB>w</SB>) of quantum well layers compatible with that of strain amount (ε<SB>w</SB>) and layer thickness (L<SB>w</SB>) within limit of critical film thickness in a strain multiple quantum well semiconductor laser.  <P>SOLUTION: The strain amount as an entire of the multiple quantum well layers is reduced by allowing part of a group of the quantum well layers and barrier layers to be formed by average strain which is a small value or whose code is inverse even if the group of the quantum well layers and barrier layers having the average large strain value is formed in the other part. In the quantum well layer with the small strain amount, the difference of energy between an electron and hole is made smaller than that of the energy in the quantum well layer with the large strain amount.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Hermetic rotary compressor and air conditioner
Inventor: HATANO KOJI
IPC: F04C18/356
Filed: 2009-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that stable room-temperature control is limited due to reasons that: a fixed time should be elapsed until a pressure different is reduced since, if the pressure difference is left, the shortage of the starting torque of an electric motor prevents the start of a compressor when the operation of the compressor is restarted from a state that the pressure difference between a suction low-pressure gas and discharge high-pressure gas is left, since high pressure refrigerant gas discharged from a cylinder into a sealed vessel does not flow back to the cylinder partitioned by a valve when the compressor is stopped by the room air temperature control or the like from a state that the compressor is operated; and a time from the stop to the restart should be secured longer than a fixed time when the compressor is mounted to the air-conditioner.  <P>SOLUTION: A movable part of a valve partitioning between the cylinder and a hermetic vessel is optionally opened and closed to reduce the pressure difference between the suction low-pressure gas and the discharge high-pressure gas when the compressor is stopped from the operating state.  <P>COPYRIGHT: (C)2010,JPO&INPIT
