Title: Thick film hybrid integrated circuit device
Inventor: KAMIAKUTSU MASAKI
IPC: H05K1/16
Filed: 1989-06-14
Abstract: PURPOSE:To form a resistor having high accuracy with high yield and to mark a component name without increasing the number of steps by sequentially superposing a glass coating, a resin coating for protecting the resistor by printing. CONSTITUTION:A thick film conductor 4 and a thick film resistor 5 are formed on a substrate 1. A resin coating 3 is formed oppositely to an accurate resistor of a thick film resistor on a glass coating 2 formed to cover the conductor 4 and the resistor 5, and a component name 6 is marked on the coating 2. Thus, the accurate resistor is protected by the two layers of the coating 2 and the coating 3. Even if it is effected by thermal and mechanical impacts in manufacturing steps, they are not directly applied to the resistor 5 to be accurate. Thus, a high yield is provided, and the number of steps for marking the name is not increased.

Title: Liquid fuel combustor
Inventor: KITAJIMA SOUICHI
IPC: B05B17/06
Filed: 1977-12-15
Abstract: PURPOSE: For effective combustion, to control combustion rate through the process supply rate consisting of detecting the temperature of heating object and changing  the power to an ultrasonic oscillator accordingly.  
     CONSTITUTION: A warm air outlet 2 is provided on the front face of a liquid fuel combustor body 1, and an air inlet 3 on the rear face. The cool air taken in through said air inlet 3 passes through the pipe 5a of a heat exchanger 5. Thus-obtained warm air is fed to a chamber through said warm air outlet 2. The inside of said heat exchanger 5 is sectioned into upper and lower sections by a combustion board 6. The latter serves as an atomizing tank 7 having an ultrasonic oscillator 8. The room temperature coming up to a fixed value through warm air blow-out is detected by a sensor 13, and the rate of supplying power to said ultrasonic oscillator 8 is decreased accordingly. Since the input power of said ultrasonic oscillator 8 and atomization rate are proportionate to each other, combustion rate decreases through that operation so that combustion fire becomes so weak as to maintain temperature at a fixed value. Thus, wasteful combustion can be eliminated.

Title: Method for compensating proximity effect for electron beam lithography with correction of dose
Inventor: WATSON GEORGE PATRICK
IPC: H01J37/317
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To compensate the proximity effect due to short- and long-distance scatterings by setting the clearing dose of protrudent edges of pattern features as a function of the dose height and separately adjusting the incident exposure doses at the edges in terms of the pattern density. SOLUTION: A short-distance scattering correction const. k is the expression of an intersection point of the clearing dose line and a dose height representing the edges of pattern features and ranges such that 0<k<1, this indicating the intersection point of the clearing dose line and max. dose height is effectively changeable. In the adjustment of the incident exposure dose level at the edges of the pattern features based on the pattern density, the background dose level 37 decreases and increases at high pattern density regions 38 and 42, this being effective for improving the resist contrast in both types of the pattern regions.
