Title: Substrate for mounting integrated circuit
Inventor: MIYAGI TAKESHI
IPC: H01L21/52
Filed: 1985-04-30
Abstract: PURPOSE:To ensure higher mounting efficiency for a mounting substrate by eliminating the need for a process exclusively for the formation of resistance bodies and by eliminating the need for an addition space by a method wherein both ends of a resistance body is directly connected to a die-bonding pad and a prescribed wire-bonding pad. CONSTITUTION:First, a first layer 7 and then a second layer 8 is deposited on a substrate 1 by evaporation, sputtering, or the like. Patterning is next accomplished by photolithography for the formation of a die-bonding pad 3, wire-bonding pad 4 and a wiring pattern 5 and, simultaneously, a region is formed into a meandering pattern for the formation of resistance bodies 9a-9c. Next, the metal constituting the second layer 8 located on regions to be formed into resistance bodies 9a-9c is removed by etching or the like. This results in the embodiment of the resistance bodies 9a-9c. A substrate incorporating this technique is higher in packaging efficiency than a conventional packaging substrate wherein resistance bodies are formed in a region wherein an integrated circuit chip is installed. It follows therefore that the same number of IC chips may be packaged into a substitute dimensionally inferior to a substitute of the conventional design.

Title: Heat exchanger and heat exchanging method
Inventor: SUZUKI TOSHIICHI
IPC: F28F13/02
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger for exchanging heat between a medium and a high viscosity liquid through a heat transfer wall provided with a circuit for supplying a high viscosity liquid in which heat transfer efficiency is prevented from lowering by providing the heat exchanger with means for mixing the high viscosity liquid with a gas. SOLUTION: High viscosity liquid in a balance tank 20 is fed through a liquid supply tank 21 through a supply circuit 11 to a heat exchanger 10 by means of a liquid supply tank 21. Flow rate and pressure of the high viscosity liquid are measured, respectively, by means of a flowmeter 22 and a pressure sensor 23. Air is delivered from an air supply means 25 toward the high viscosity liquid being fed through the supply circuit 11 and air is admixed to the high viscosity liquid before it is fed to the heat exchanger 10. Subsequently, they are mixed by means of a static mixer 24. Since bubble-like air is mixed evenly into the entire high viscosity liquid, a film formed along the inner surface of a heat transfer wall touching a highly combustible liquid in the heat exchanger 10 can be made thin while preventing the total heat transfer coefficient from lowering.

IPC: H01S5/00
Filed: 1988-04-15
Abstract: PURPOSE:To effectively confine the light in the upward and downward directions by a method wherein two or more semiconductor thin layers which have a specific energy gap and a specific refractive index and whose composition is of two different kinds are eliminated in a position corresponding to the upper part and lower part of an active layer. CONSTITUTION:A p-type clad layer 5 is formed at the upper part and an n-type clad layer 3 is formed at the lower part, of an active layer 4 as a light-emitting layer. A p-type reflection film 10 which is constituted by alternately laminating two or more sets of semiconductor thin films 11 and 12 is formed at the upper part of the layer 5. An n-type reflection film 20 which is constituted by alternately laminating two or more sets of semiconductor thin films 21 and 22 is formed at the lower part of the layer 3. In this structure, an energy gap in the layer 4 is smaller than that in other layers; a refractive index in the layer 4 is larger than that in other layers. In addition, when a light-emitting wave-length in the layer 4 is designated as lambda, a thickness of the thin films 11, 12, 21 22 is set to a value obtained by multiplying lambda/4 by a retractive index of each layer. By this setup, it is possible to enhance the light-emitting efficiency and to make effective use of emitted light.

Title: Setting system for developing bias
Inventor: IGUCHI HIROSHI
IPC: G03G15/06
Filed: 1983-05-25
Abstract: PURPOSE:To set automatically a proper bias voltage by writing a specific mark on a photosensitive drum, and deciding on the state of a developed mark and detecting the extent of deterioration of a developing material. CONSTITUTION:Plural lines are recorded at specific positions on the photosensitive drum. When the bias voltage is proper, respective lines have linear edges and have no internal irregularity as shown by A. Those lines are read optically to obtain a waveform B showing that the bias voltage is proper. If the developing material deteriorates and the bias voltage becomes unsuitable, toner does not stick to the center parts of the lines as shown by C to form white absence, edges of the lines are blurred, and the difference between light and shadow levels decreases, so an optically read waveform varies in frequency as shown by D and decreases in amplitude. Fro such a purpose, the variation in frequency and amplitude are detected and compared with predetermined values to adjust the bias voltage automatically.
