Abstract: PURPOSE:To prevent unrequired data from being recorded and to detect tracking information with high precision by applying DC free modulation on data to be recorded generally, disturbing the DC free modulation at a certain point on a track, and setting disturbance differently between adjacent tracks. CONSTITUTION:A magnetic head 6 modulates a data string 17 to be recorded in track length by a modulator 4, however, a modulation rule in modulated output 17 is disturbed in periods (19-27). The DSV (Digital Sum Variation) of each block of the modulated output 18 goes to '0' in the periods (19-27), and the modulation rule is disturbed, then, it changes like DSV28, and in the DSV28 and 29, the disturbance of the modulation rule are set differently between the adjacent tracks. At the time of reproduction, a signal is introduced to a demodulator 9 and a filter 14, and the modulator 4 performs a DC free operation almost in all periods, and the DSV changes in extremely limited period. Therefore, different signals between the adjacent tracks can be obtained from the filters 14. In such a way, it is possible to detect a tracking error correctly as holding a recording and reproducing function.

Title: Injection amount controlling method for electronically controlled diesel engine
Inventor: SUGIYAMA KOICHI
IPC: F02D41/38
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To calculate the main spill valve opening/closing timing capable of controlling the injection amount properly even if NE pulse crack is generated and to correct erroneous data resulting from generation of NE pulse crack. SOLUTION: The first main spill valve opening/closing timing calculated in the same manner as in a conventional control is calculated and also the second main spill valve opening/closing timing is calculated using a reference which is NE pulses for calculating the final pilot spill valve opening timing free of influence even if NE pulse crack is generated, and the obtained two valve timings are compared. In the case where an NE pulse crack is generated, a first valve timing becomes earlier than normal, and therefore, if the first valve timing is earlier than a second valve timing, judgement is passed that generation of NE pulse crack is likely. If on the contrary, the first timing is later than the second timing, judgement is passed that no NE pulse crack is generated.

IPC: H01L21/027
Filed: 1988-02-29
Abstract: PURPOSE:To prevent a substrate from being charged electrostatically with an electron beam which is projected from a scanning electron microscope by covering the surface of at lest the insulation part of the pattern and substrate of a sample with a conductive thin film which can be peeled with water, a solvent, etc. CONSTITUTION:When the sample 3 is constituted by forming the fine pattern 2 of a conductor on the surface of the substrate 1 made of an insulator, the surface of the sample 3 on the side of the pattern 2 is covered with the conductive thin film 4 which can easily be peeled off with a solvent, etc. Consequently, the substrate 1 can be prevented from being charged electrostatically with the electron beam which is projected from the scanning electron microscope. Therefore, an accurate image having no distortion can be observed without lowering the acceleration voltage of the electron beam of the electron microscope. The conductive thin film 4 can easily be peeled off with the solvent after the observation is performed through the microscope.

Title: Image forming device
Inventor: MARUYAMA HIROYOSHI
IPC: G03G15/04
Filed: 1988-02-29
Abstract: PURPOSE:To enable a frame erasing in a large area with sufficient quantity of light for frame erasing by placing in combination an optical path limiting material, which is fixed in between a charge eliminating light source and an image carrier, and a movable light shielding material. CONSTITUTION:A movable slit 4, which is the light shielding material to limit the irradiating area of the charge eliminating beam, is placed between a mirror 8 and openings 2a-2d of a frame body 2, and this movable slit 4 is fixed onto a slit mount 3, provided on the frame body 2. The lens mount 14 responding to the projecting magnification of an image to the photosensitive body 1, travels along a guiding rail 16, within the optical path between the original and the photosensitive body 1, and a cam 13 fixed onto the lens amount 14 travels in the direction of an arrow B. Therefore, the slit mount 3 follows through a pin 3a, and the movable slit 4 travels with the traveling of the slit mount 3. At this time, the movable slit 4 is placed in the optical path from lamps 5 to the photosensitive body 1, and the irradiating area of the photosensitive body 1 is limited from each of the lamps 5 by the photosensitive body 1 traveling in a longitudinal direction. Thus a frame erasing of the image in a large area can be carried out.

Title: Start-stop circuit for control ic
Inventor: MAESAKA MASAHARU
IPC: H02M3/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a hysteresis characteristic for start-stop, with a simple circuit configuration and a small number of external components. SOLUTION: A reference voltage circuit which is built-in in a control IC-1 outputs the reference voltage Vr, when the control IC-1 starts the operation. A voltage conversion circuit 2 converts the input supply voltage Vi into the voltage Vp which is suitable for a remote controller terminal 14 of the control IC-1. A hysteresis circuit 3 divides the input voltage Vp from the voltage conversion circuit 2 into high and low voltages and connects a voltage dividing point 3a of a higher voltage to the remote controller terminal 4 of the control IC 1 to output the divided voltage Vs, while connecting a voltage dividing point 3b of a lower voltage to a reference voltage output terminal 5. The control IC 1 is started up by the divided voltgae Vs, when the input voltage Vp is a specified start-up voltage Va or above.  Under the operation of the control IC, the voltage voltage Vs is stepped up since the reference voltage Vr is input in addition to the conversion voltage Vp of the voltage conversion circuit, and the stop voltage Vb of the control IC is made lower than the start-up voltage Va and thereby a hysteresis characteristic is obtained.

Abstract: PURPOSE:To perform sure titled soldering free from short circuiting and malfunction by soldering electrical parts to the prescribed copper foil parts of a printed wiring substrate in the build-up parts of the surface of a solder soln. produced by foam then applying finish soldering. CONSTITUTION:In a foam introduction type soldering tank 1, foam is produced from release holes 3, 3' through an introduction pipe 2. Here, a printed wiring substrate 4 is introduced and the electrodes 7 of chip elements 6 are soldered to copper foil parts 8 near the peaks of the build-up of the surface of the solder soln. by the foam. In this case, the solder does not scatter to the surface opposite to the soldering surface 5 through the through-holes 9 of the substrate 4, but the sticking of the solder spatters on the surface 5 on account of bursting of the foam can occur. Therefore, if finish soldering is applied in a static type soldering tank 10, the thorough soldering is accomplished and the stuck solder spatters are removed. The similar effect is obtained by using a jet type soldering tank is this finish soldering stage.

Filed: 1978-04-21
Abstract: PURPOSE: To prevent blast furnace gas from entering into a dust separator etc. during blowing  down of a blast furnace in order to keep working environment safe and to make the discharge of  dust from the dust separator easy, by installing a manhole at the upper part of the dust separator  of a blast furnace, and by arranging a burner or nozzle for injecting high-temp. air.   
     CONSTITUTION: During blowing down of a blast furnace 11, high-temp. exhaust gas high in CO  concn. is discharged to the air through a rising pipe 10, and a bleeder valve 9. A portion of the  exhaust gas enters by way of a descending pipe 8 into a dust separator 7 and deteriorates the  working environment with toxic CO. At the lower end of the descending pipe 8 of the dust separator 7, or at other suitable position is installed a manhole 22, which is opened or closed at need,  through which a burner 1 for heating air, or a nozzle for injecting high-temp. air is inserted.  Combustion of gas by the burner 1 or injection of high-temp. air through the nozzle causes to discharge blast furance gas in the descending pipe 8 and to replace toxic gas in the dust separator 7  with harmless air. Dust is discharged easily without sticking to the separator 7 with water becuase  the combustion gas or air contained in the dust separator is maintained at high temp.
