Filed: 1987-05-09
Abstract: PURPOSE:To enhance a pinch-off characteristic and to realize a high-speed operation by installing a buffer layer which has an active layer composed of InGaAs and is composed of a superlattice where InAlAs and InAlGaAs are laminated alternately so that the generation of, a two-dimensional electron gas on the side of the buffer layer in an active layer can be suppressed. CONSTITUTION:A high electron-mobility transistor is constituted by a semiinsulating InP substrate 11, an InAlAs/InAlGaAs superlattice (a buffer layer) 12, an undoped InGaAs layer (a channel layer; an active layer) 13, an n-InAlGaAs layer (an electron supply layer) 14, an n-InGaAs layer (a contact layer) 15, a gate electrode 16, a source electrode 17 and a drain electrode 18. If the superlattice as the buffer layer 12 is constituted by InAlAs and InAlGaAs in this manner, an InAlGaAs (quaternary) conduction band is at a high level; a difference between the conduction band of InAlAs and that of InAlGaAs becomes small; it becomes difficult for a donor in a deep impurity level of InAlAs to move beyond InAlGaAs. Accordingly, it is possible to suppress the generation of a two-dimensional electron gas on the side of the buffer layer 12 of a hetero interface.

Abstract: PURPOSE:To enable to perform a uniform heat treatment even when the temperature of a sample rises while an electron beam is being scanned by a method wherein a function, with which the scanning speed of an electron beam will be increased as time elapses, is added to the titled device. CONSTITUTION:Every time when a scanning is finished for one step in x-axis direction, the coincidence signal COMX outputted from a comparison circuit 23 is sent to the central processing device 1, and a signal FD to be used to increase the frequency of a clock signal CLOCK is sent to a clock generation circuit 17 from the central processing device 1. As a result, every time when the scanning for a step in x-axis direction is finished, the counting speed of a counter 18 is increased, and the boosting speed of the voltage XD applied to the deflector in x-axis direction is increased, thereby enabling to increase the scanning speed in x-axis direction. Also, the irradiation dose on the specific region of the electron beam per unit time is reduced with the increase of the scanning speed in x-axis direction as time elapses even when there generates the necessity of reduction in irradiation dose of the electron beam when the temperature of the sample is gradually increased due to the heat-storage effect of the sample.

Filed: 1987-05-12
Abstract: PURPOSE:To extremely reduce memory capacity by dividing a graphic pattern for each block and at the same time extracting a block including a graphic pattern out of those divided blocks to store only the graphic pattern in the extracted block. CONSTITUTION:An input graphic pattern is stored in a pattern memory means 4 and then divided into blocks for each character of a text memory 1 by an allocating means 2. Then only the block including a graphic pattern is extracted by an extracting means 3 and only graphic data in the extracted block is stored in a graphic control means 4. An output control means 5 reads data on the characters corresponding to the blocks storing the graphic data out of the means 4 together with the corresponding graphic data when the character data is outputted from the memory 1. These readout data are converted into a synthetic pattern and outputted 1. Thus a graphic pattern can be stored in the minimum and necessary pattern and therefore the memory capacity is extremely reduced.

Title: Muffler for internal combustion engine
Inventor: SUZUKI MITSUO
IPC: F01N1/08
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To make the opening of a valve disc the larger sufficiently as the rotation frequency of an internal combustion engine is made the larger, in a muffler for internal combustion engine having a valve disc which can open and close a bypass flow passage. SOLUTION: A valve disc 32 which can open and close a bypass inner pipe 28 is supported swayable to the stay 35 of the bypass inner pipe 28, through a swelling form of bent plate spring 37 whose cross section is swelled to the exhaust gas downstream side. Since the bent plate spring 37 is in the swelling form in the cross section, until the valve disc 32 reaches to a specified opening from the blocking position, the opening load necessary to open the valve disc 32 is relatively large (1 and 2). But since the cross section of the bent plate spring 37 is moved from the swelling form to an about linear form, when the opening of the valve disc 32 exceeds the specific opening, the opening load is reduced (3). After the bent plate spring 37 is mad to an about linear form in the cross section, the opening load is made larger slowly, as the opening of the valve disc 32 is made larger.

Abstract: PURPOSE:To achieve the switching to an analog three-primary color signal with a simple circuit constitution, by making the switching of a voltage setting luminance level of background and character with a luminance designation signal and connecting a setting voltage to a switch circuit switched with a digital three-primary color signal. CONSTITUTION:Voltages VB1, VB2 of resistors R1, R2 of a variable resistor 12 are applied to the base of TRs Q4, Q3 as voltages VQB1, VQB2 via transistors TRs Q2, Q1 constituting a buffer circuit. Since the TRQ3, Q4 are constituted differentially, when a luminance designation signal YD is 1 and the background part is designated, a voltage VE is almost voltage VQB1 because of conduction of a TRQ5. When digital color signals RD, GD, BD are applied to input terminals 4-6 as 1, switches 14-16 are opened, and the voltage VE is applied to the base of TRs Q6, Q7, Q8. Thus, analog color signals RA, GA, BA are outputted to output terminals 8-9. Thus, the signal switching is constituted with a simple circuit and the adjustment between the luminance and the contrast is made without changing the rate of the luminance.

Title: Copying machine
Inventor: TSUJIMURA TSUTOMU
IPC: G03B27/72
Filed: 1985-05-29
Abstract: PURPOSE:To control copying density on the basis of a measured value of the light transmissivity of an original and to attain optimum copying by measuring the transmissivity prior to the copying. CONSTITUTION:When an original is inserted, a transmissivity detector 3 detects the transmissivity of the original. The original is superposed to photosensitive paper and simultaneously sent to a photosensitive part 7. A paper passage detector 6 is arranged on a position immediately before the photosensitive part 7 to check the arrival of the original. When the original reaches the position of the detector 6, the detector 6 determines a proper paper feeding speed in accordance with the transmissibility found out by the detecting part 3 to pass the original through the photosensitive part 7. A paper passage detector 6 is also arranged on a position immediately after the photosensitive part 7 to check the end of the passage of the original. When the original passes the position of the detector 6, the paper feeding speed is returned to the original speed and the original and the photosensitive paper are discharged from an original outlet 4 and a photosensitive paper outlet 5 respectively. Thus, the copying density can be controlled and the optimum copying can be attained.
