Title: Heat conveying circuit
Inventor: MIYAHARA SATOSHI
IPC: F28F9/22
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in an air side heat transfer rate and to suppress a decrease in a cooling capability of a heat conveying circuit in the circuit for conveying the air or the like, in a refrigerator used for an air forcibly circulating type cooling equipment such as a cold storage cabinet, a refrigerator with a deep freezer or the like to communicate a heat between the refrigerant and the fluid such as the air. SOLUTION: Louvers 8 are provided at a surface of fins 7 of a heat exchanger with the fins so that an opening 9 becomes substantially perpendicular to the air flowing toward the exchanger 6 from a wall 5 by the air flowing through a bypass air duct 5. Thus, since a temperature boundary layer is most effectively updated while suppressing an increase in a ventilating resistance, and a heat transfer rate of the air side can be improved, a decrease in the cooling capability of the heat conveying circuit can be suppressed.

Title: Bipolar transistor
Inventor: MEGURO KEN
IPC: H01L21/331
Filed: 1988-04-20
Abstract: PURPOSE:To improve the performance of an integrated circuit device and to rationalize the manufacture by providing an emitter region so diffused in other conductivity type as to form a predetermined base width to a collector region in a base region, thereby forming a transistor having a high current amplification factor and a high operation speed in a high integration with good reproducibility. CONSTITUTION:An emitter region 9 is so diffused in a base region 7 as to form a predetermined base width to a collector region 5, the base width is formed laterally, i.e., in a direction substantially parallel to the surface of a substrate different from a conventional one, and the region 7 is so diffused as to arrive at a buried base region 4 thereunder. Thus, after an emitter current implanted from the emitter region to the base region pass longitudinally the base region, it can immediately flow to the buried base region. Accordingly, even if the base width is so sufficiently narrowed as to raise its current amplification factor, its base resistance is not substantially increased.
