Title: Time-decomposed light-emitting-spectrum measuring method
Inventor: HARA KIYOAKI
IPC: G01J3/44
Filed: 1983-10-13
Abstract: PURPOSE:To shorten the measuring time and to make it possible to form necessary and correct time-decomposed, light-emitting spectrum, by sequentially storing the measured light-emitting transient waveforms into the outer memory of a computer, and performing data processing. CONSTITUTION:A spectroscope 4 is provided between a sample 2 and a light emitting detector 5 of the sample. Light-emitting transient waveforms are measured at every arbitrary wavelength in a light-emitting spectrum region in problem. The measured light-emitting transient waveforms are sequentially stored in an outer memory 15 of a computer 14 at every wavelength. After all the transient waveforms at every wavelength have been measured, the time-decomposed spectrum is formed by the data processing of the computer 14 based on the various light-emitting transient waveform data.

Title: Manufacture of multilayer printed circuit board
Inventor: ABE KAZUMASA
IPC: H05K3/40
Filed: 1991-07-31
Abstract: PURPOSE:To obtain a smooth substrate by filling a through hole with a metal paste mainly comprising gallium to obtain conductivity and then exposing the metal paste at the same surface of the substrate. CONSTITUTION:A through hole 8 is formed for interconnecting between wiring patterns 6. This through hole 8 is filled with a gallium alloy paste and an excessive gallium alloy paste is wiped out. This process is realized by placing a board on a stainless plate and the through hole 8 is filled with pressure with gallium alloy paste 9. This gallium alloy paste 9 has the property to maintain its paste condition under the stocking temperature and make reaction under the successive heat treatment and is thereby alloyed into the solid condition by the aging effect. Accordingly, before the gallium alloy paste is hardened, it can be supplied easily into stainless under the paste condition and does not show deposition and contraction after it is hardened. As a result, the surface of gallium alloy paste 9 is exposed on the same surface as the resin layer 7 and a smooth substrate can be obtained.

Filed: 1985-09-02
Abstract: PURPOSE:To reduce the size of a copying machine by providing a mode in which one idle rotation is made between rotations of a photosensitive body where toner images of different colors are formed and an original scanning system returns in the idle rotation. CONSTITUTION:While the photosensitive body 11 performs the 1st rotation, EY image exposure incidence and the DY development of an electrostatic image formed by said exposure are carried out and while the body 11 performs the 2nd rotation, the optical system moves back and none of developing devices 13-16 is in operation.

Title: Air pump setup structure for air-fuel injection two-cycle engine
Inventor: ISAKA YOSHIHARU
IPC: F02B61/00
Filed: 1990-07-19
Abstract: PURPOSE:To improve the extent of compression efficiency without hindrance to a driving attitude by setting up an air pump in a cylinder body side part in and around a generator or clutch at one side of a crankcase, and connecting this air pump and an air-fuel injection valve through a high pressure passage. CONSTITUTION:An air pump 33 is vertically set up at the side of a cylinder body 3, and its discharge part is situated at the side of an air-fuel injection system 13. With this constitution, a distance from the air pump 33 to an air rail 14a of the air-fuel injection system 13, namely, a high pressure passage 70 gets off with a shorter one, and any possible drop in pressure in compressed air in the midway of the passage is reduced, thus compression efficiency becomes so better. In this connection, the air pump 33 may be set up in a part at the cylinder body 3 in and around a magnet cover 18 covering a flywheel magnet 17. Since the air pump is set up so as to be projected out of a crankcase, any possible hindrance at driver's feet, etc., is thus avoidable.

Title: Undercut shape molding method of powder molded goods and its molding device
Inventor: TAKAYAMA YASUSHI
IPC: B22F3/03
Filed: 1993-08-03
Abstract: PURPOSE:To eliminate the need for deburring in a post stage by rotating plural molding members around the central axial line of molded goods after the end of pressurization, then retreating the members from a die space. CONSTITUTION:Material powder 71 is press molded by actuating upper and lower punches 35, 37 and upper and lower second punches 41, 47. Burrs P are generated at the butt surfaces at the front ends of cam die plates 31, 33. These cam die plates 31, 33 are simultaneously rotated at a prescribed angle theta. The upper and lower punches 35, 37 are slightly retreated at the time of rotation to decrease the stresses acting on the cam die plates 31, 33 so that the cam die plates 31, 33 easily rotate. Consequently, the burrs P formed on the outer periphery of an undercut part 51 are removed. The cam die plates 31, 33 are rotated in a backward direction and are returned to their home positions after the removal of the burrs P. The molded goods are then taken out by retreating the die plates.

Title: Photoelectric conversion method and device therefor
Inventor: NISHIMOTO IKUO
IPC: H01L31/16
Filed: 1993-08-03
Abstract: PURPOSE:To provide an equivalently short light receiving section by dividing each photoelectric current of light receiving elements into four portions to a specific ratio and introducing the current to respective output ends, while establishing a specific relation among the ratios. CONSTITUTION:Photoelectric current each from respective light receiving elements is divided into four portions to a specific ratio, and introduced to respective photoelectric current output ends. Then, as a result of a relationship established between each ratio, the photoelectric current of the light receiving elements in a zone where a suffix (j) ('j' is between 1 and 'n') corresponding to the prescribed distance from a suffix (j0) drops, is obtained from the first photoelectric current output end. The photoelectric current of the elements with less (j) in the same zone can be obtained from the third photoelectric current output end. Similarly, the photoelectric current of the elements in a zone where (j) corresponding to the predetermined distance from (j0) increases, is obtained from the second photoelectric current output end. Also, the photoelectric current of the elements with a larger (j) is obtained from the fourth photoelectric current output end. Consequently, the photoelectric current of 'n' pieces of the elements becomes equivalent to a case where photo sensitive surface is divided into four portions.
