Title: Manufacture of epitaxial wafer
Inventor: KANAMORI KATSU
IPC: H01L21/205
Filed: 1985-08-16
Abstract: PURPOSE:To improve the electric characteristics of an element and to suppress the generation of a defect by diffusing in advance boron before epitaxial growing. CONSTITUTION:After boron of 1X10<19>cm<-3> or more is diffused in the entire or specific portion of a P-type substrate added with boron of 0.01-0.02OMEGA.cm of specific resistance with remarkable difficulty in manufacture, it is epitaxially grown. In other words, when the boron is diffused in high density to the depth necessary to prevent a conductive type from being inverted, there is no problem in the sufficient function of an element, and there is sufficient function even by a method of diffusing only in the specific portion necessary in a circuit. A thermally diffusing method is adapted for the efficient diffusion, and the diffusion to the specific portion can be performed by the masking action of an oxide film.

Title: Control method for lighting timing of exposure lamp
Inventor: AOKI MINORU
IPC: G03G15/04
Filed: 1986-07-31
Abstract: PURPOSE:To suppress the excess temperature rise of an exposure lamp by turning off the lamp at the time of returning a scanner, setting up the lighting start timing of the lamp to a point of time retoacted by the time required for the rise of the lamp from immediately before the arrival of the scanner at the leading edge and delaying the lighting start timing in accordance with the increase of continuous exposure frequency. CONSTITUTION:The 1st scanner 6 consisting of an exposure lamp 4 and the 1st mirror M1 and the 2nd scanner 8 consisting of the 2nd and 3rd mirrors M2, M3 are arranged under a contact glass 2 on which an original G is set up so as to be reciprocated. Reflected light from the mirror M3 is made incident upon a photosensitive drum 10, through an image formation lens 9 and the 4th mirror M4 to form an electrostatic latent image. Since the rising time of the exposure lamp is shorter when a lamp temperature just before lighting is high as compared to the case of a low lamp temperature under said constitution, lighting is started on the basis of the rising time of the low temperature case at the time of 1st copy. At the 2nd copy and after, remaining heat generated at the time of preceding lighting is utilized and the ignition start timing is delayed from the timing of the 1st copy.

Title: Wire impact printer device
Inventor: YAMANAKA NORIO
IPC: B41J13/00
Filed: 1989-07-13
Abstract: PURPOSE:To eliminate the factors of the damage of a printing head, such as the breakage of a wire, by prohibiting a printing action to a cutform having a paper thickness more than a predetermined value. CONSTITUTION:A paper thickness detector 21 connected to an input/output port of a microcomputer 22 conducts a detection action when a paper thickness detection request signal is transmitted from the microcomputer 22. A detected paper thickness signal is read by the microcomputer 22. In the microcomputer, a paper thickness value is set in a RAM or a ROM. With this value set to, e.g., 0.2mm, if the paper thickness signal from the paper thickness detector 21 is judged to be more than 0.2mm in the comparison with the set value, a paper discharge request signal and a paper feed request signal are transmitted to an automatic paper feed/discharge device 23 to make it conduct a paper discharge action and an automatic paper feed action. Furthermore, a fed paper presence/absence detector 24 does not transmit any signal to the automatic paper feed/discharge device 23 when the paper thickness signal is 0.2mm or less.

Title: Control method for pump operation
Inventor: KUWAKI MITSUNOBU
IPC: F04B11/00
Filed: 1980-12-19
Abstract: PURPOSE: To control the pump so as to reduce the suction rate when the cavitation is generated by a method wherein the sound or vibration produced at the generation of cavitation is memorized and the generation of cavitation during the running of the pump is judged from said memorized information.  
     CONSTITUTION: The output of an acoustic measuring instrument 8 mounted on a cargo oil pump 2 is inputted in a control unit 9 equipped with a computer. The pump 2 is actually operated under the condition that the sound produced is measured throughout the operation and the sound pressure, sound frequency and the like at the generation of cavitation are memorized in the control unit 9. Once the pump 2 is operated and, when the liquid level of cargo oil lowers to the predetermined position, the control unit 9 is put into operation to successively measure the sound produced so as to decide the generation of cavitation by comparing the measured value with the memorized value. When the control unit 9 decides the generation of cavitation, a valve 7 is automatically throttled or the rotational frequency of the pump 2 is automatically lowered.

Filed: 1989-07-12
Abstract: PURPOSE:To surely protect the stored data by displaying a fact on a display device that an available period calculated from the storage starting date data stored in a RAM card and the date data received from a clock mechanism exceeded the prescribed threshold value. CONSTITUTION:A process control part 11 registers the storage starting date data on a RAM card 16 into a prescribed area of the card 16 based on the instruction input data received from an input device 14. At the same time, the part 11 reads the storage starting date data out of the card 16 in a data reading mode of the card 16 and calculates an available period from the storage starting date data and the date data received from a clock mechanism 13. Then the part 11 displays a fact that the available period of the card 16 is expired on a display device 15 when the calculated avilable period exceeds the prescribed threshold value. Thus a user can know the limit of the data storage of the card 16 and can replace a battery, copy the data and consider other counterplans. As a result, the existing data can be continuously used.

Title: Ghost eliminating device
Inventor: INMI MASABUMI
IPC: H04N5/21
Filed: 1985-08-21
Abstract: PURPOSE:To prevent the deterioration of the S/N of the output video signal by providing a high band compensating circuit at the input side of a transversal filter. CONSTITUTION:A high band compensating circuit 701 is set before a transversal filter 403 to compensate the deterioration of the high band component of the signal eliminating the ghost produced in the filter 403. Thus the circuit 701 never amplifies the high band component of the noise produced in the filter 403. Furthermore the high band component of the noise contained in the input video signal if amplified by the circuit 701 is attenuated considerably by passing the filter 403. As a result, the deterioration of the S/N of the output video signal is avoided by inserting the circuit 701.
