Title: Method for liquid-phase epitaxial growth and growing boat
Inventor: NAKAI SABUROU
IPC: H01L21/208
Filed: 1980-08-05
Abstract: PURPOSE:To reduce the edge growth layer of a wafer and prevent deterioration of a quality by epitaxial growth in the state under which a growing solution makes contact with the side of a substrate edge. CONSTITUTION:A growing solution 14 is separated with partition board 11 of a slider part and poured into a solution tank 13 which is covered with a lid 12.

Title: Automatic exposure adjusting mechanism of reader printer
Inventor: SUZUKI HIROMASA
IPC: G03B27/32
Filed: 1983-06-15
Abstract: PURPOSE:To obtain an inexpensive mechanism by utilizing turning of a mirror to scan a light quantity detecting sensor provided in a position across the optical path of the turning mirror. CONSTITUTION:If data to be copied exists on a microfilm 1, a changeover switch 7 is switched, and a turning mirror 3 starts turning in the direction of an arrow N1. At this time, a timing control circuit 12 releases a reset signal RS, and the output of a light quantity detecting sensor 8 is inputted to an integrator 9. The timing control circuit 12 outputs a mode signal MD to an exposure adjusting circuit 11, and the exposure adjusting circuit 11 gives a certain voltage to a light source 2. While the turning mirror 3 is turned, the light quantity detecting sensor 8 continues measuring a light LT, and it is integrated by the integrator 9. The timing control circuit 12 turns off an on/off switch 10 again; and at this time, the integrator 9 keeps a certain output S, and it becomes a measured value of the light LT transmitted through the microfilm 1. When the light LT reaches a copy system 6, the exposure adjusting circuit 11 adjusts the voltage of the light source 2 to a proper value on a basis of the output S and a correct exposure target value REF. Thus, the quantity of light in a wide range is measured to attain inexpensively a copy corresponding to the density of the microfilm.

Title: Dot printer
Inventor: NITTA NOBORU
IPC: B41J2/485
Filed: 1990-04-25
Abstract: PURPOSE:To prevent sinking of a paper and abrasion of a dot head, to restrict the printing sound and to make small the capacity of a driving source of the dot head by providing a printing image data correcting means for thinning a printing dot if the printing dot of the printing image data stored in a buffer memory is surrounded with dots in every direction, i.e., up and down and right and left. CONSTITUTION:A CPU 1 forms a printing image data of a dot pattern from the printing data input from a host device, and stores the image data in a buffer memory within a RAM 3. The printing image data is corrected by a printing image data correcting means. It is checked first whether the printing image data is a dot to be printed. If it is an effective dot, it is checked whether it is at the right side, left side, upper side or lower side. When there are dots in every direction of the target dot, the target dot is thinned. In the case where the target dot is not an effective dot, or if there is a dot absent in one direction of the target dot, the target dot is not thinned. This process is performed sequentially for every dot of one column. When one line is completed, the correcting process is finished and the printing process is started.

IPC: B23K26/382
Filed: 1993-05-10
Abstract: PURPOSE:To effectively protect converging optical parts from molten metal scattering at the time of working. CONSTITUTION:By a shielding device 20 provided between a condensing lens 12 and a work 13, a shield plate 20c is moved back and forth in an arrow 30 direction in accordance with a command signal from a control device 10.

When the pulsed light 14 reaches the work 13 and the surface of the work 13 is heated to a high temp., a molten metal 15 begins to scatter from the surface; since the shield plate 20c is operated to shield between the condensing lens 12 and the work 13 by then, the scattered molten metal 15 is shielded by the shield plate 20c and unable to reach the condensing lens 12. Consequently, the condensing lens 12 is basically protected from being stained by the molten metal 15.

Abstract: PURPOSE:To improve a frequency characteristic, to heighten the peak value of a signal and also, to perform a fast operation, and to improve an S/N by damping a noise by providing a low-input impedance amplifier and a non- inversion input signal adder, etc. CONSTITUTION:The low-input impedance amplifier AMPA inputs signals from photoelectric converter blocks B1 and B2, etc., and outputs a sharp signal with a high peak value.
