Title: Silicon carbide vertical type bipolar transistor and its manufacture
Inventor: UENO KATSUNORI
IPC: H01L29/73
Filed: 1994-09-05
Abstract: PURPOSE: To increase the controllable current and enlarge the safe operation region in the case of switching, in a silicon carbide vertical type bipolar transistor. CONSTITUTION: In a silicon carbide bipolar transistor wherein an N-type collector layer 24, a P-type base layer 22 and an N-type emitter layer 23 are laminated in order, a trench 29 reaching the P-type base layer 22 from the surface of the N-type emitter layer 23 is formed. A base electrode 26 is formed in the bottom of the trench 29, and an emitter electrode 25 is formed on the base electrode 26 via an insulating film 30. The isolation distance between the emitter electrode 25 and the base electrode 26 is set not in the lateral direction but in the vertical direction, so that the substrate area can be effectively used. Since the width of the emitter layer 23 can be reduced, the ineffective region distant from the base electrode 26 can be reduced. Since a collector current can be rapidly led out from the base electrode 26, imperfect turn-off due to residual carrier is not caused.  Thereby a bipolar transistor whose safe operation region is large can be obtained.

IPC: G01F1/692
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To easily measure the average flow rate of a fluid with high accuracy even when the fluid is in an undeveloped state by measuring the flow velocity of the fluid in a plurality of directions at a plurality of measuring points and averaging the measured flow velocities in each direction, and then, multiplying the average flow velocity in each direction by a correction factor. SOLUTION: Many supporting bodies 2, on each of which flow velocity detecting elements 4x, 4y, and 4z directed in the x-, y-, and z-axis directions are arranged, are arranged at prescribed positions in the flow passage of a fluid so as to measure the flow velocity of the fluid in the x-, y-, and zaxis directions at the measuring points. The average flow velocity of the fluid in each direction is found by averaging the measured flow velocities of the fluid in each direction obtained at the measuring points and multiplying the average flow velocity in each direction by a correction factor, and then, averaging the corrected flow velocities. After the average flow velocity is found, the flow rate of the fluid is calculated. A thermal type flow velocity detecting element, turbine type flow velocity detecting element, etc., can be used as the flow velocity detecting elements.  When the thermal type element is used, the element can be positioned easily in a gas pipe through a small inserting hole, because the flowmeter itself can be made extremely small in size.

Title: Temperature sensing structure for integrated circuit package
Inventor: UMEZAWA KAZUHIKO
IPC: H01L23/34
Filed: 1988-08-26
Abstract: PURPOSE:To dispense with special steps of installation and removal of a package and thereby to prevent the package from damage to be otherwise generated owing to mistakes in handling by a method wherein a temperature sensor is housed at the same level as an integrated circuit element in a case and is connected to the outside for sending out signals through the intermediary of a circuit board which the element also shares. CONSTITUTION:Heat generated by an integrated circuit element 1 travels to a cooler 12 through a heat conducting compound 17 and then sinks into a liquid coolant running in a coolant path 15. The case 5 of a temperature sensor 2 is as high as the integrated circuit element 1, and the gap between the case 5 and a sensor 3 is filled with the heating conducting compound 17. With the temperature sensor 3 being bonded to the cap 8 of the coolant 12 using a heat conducting adhesive, temperatures may be measured of the faces of the coolant 12 and the element 1 opposite to each other. The output of the sensor 3 is taken out at an input/output pin 10 of a circuit board 9 through the case 5. This setup dispenses with the need for a special operation for the installation or removal of a package and eliminates protrusions in parts, which prevent damage that may otherwise occur owing to mistakes in handling.
