Title: Picture signal processor
Inventor: HANAOKA HIDEYUKI
IPC: H04N1/40
Filed: 1983-12-15
Abstract: PURPOSE:To improve the quantizing accuracy of an original signal and the contrast at reading of an intermediate tone picture original by setting the amplification factor of a variable gain amplifier circuit during the input period of a white reference board signal. CONSTITUTION:During the period when the white reference board is scanned by an image sensor 3 and a white reference board signal is inputted, switches 10, 16 are both turned on by signals S1, S2. After the white reference board signal outputted from a variable gain amplifier circuit 1 is attenuated to R4/(R3+R4) times by a signal attenuation circuit 13, the signal is inputted to a comparator 12. Thus, a control voltage Vc having a value where the peak value of the white reference board signal outputted from the circuit 1 is VpX(R3+R4)/R4 is generated across terminals of a capacitor 9. Then the original scanning is started by an image sensor 3, and the switches 10, 16 are turned off by the signals S1, S2 just before. Thus, the control voltage Vc is fixed. Thus, the amplification degree of the circuit 1 is fixed.

Title: Paper feeder
Inventor: HARADA MITSURU
IPC: B65H1/12
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent double feed of transfer paper sheets by providing a placing plate and a cassette opposite thereto with a connecting means for keeping the placing plate in the depressed state, and setting the release time for the depressing state of the connecting means after the completion of installing a paper feed cassette in an image forming apparatus main body. SOLUTION: When a placing plate 3 is depressed against the forcibility of an elastic body 6, a magnet 7 and a magnetic body 8 are kept in the closely adhering state. When a paper feed cassette 2 is installed in a paper feeder 1 to reach the installation completion position on a guide rail 1A, a detection signal is output from an installation completion detecting means 9 to a control part 11, and in the lapse of designated time, a magnetism generating means 10 is started, so that the placing plate 3 is separated from the magnetic body 8 to bring the placed transfer paper sheets S into contact with a paper feed roller.  As the placing plate 3 is pushed up after the completion of installing the paper feed cassette 2, when the cassette reaches the installation completion position in the paper feeder 1, even if impact force is generated, it is possible to prevent the situation where the transfer paper sheet S runs on the upper surface of a corner claw 4.

Title: Portable radio equipment case
Inventor: HAYASHI TAKAHIRO
IPC: H04B1/38
Filed: 1988-09-21
Abstract: PURPOSE:To cause plastic deformation and to maintain the capability clipping an inserted member providing a 1st spring supporting a clip elastically and a 2nd spring fitted between the 1st spring and the inside of the main body. CONSTITUTION:When an inserted member is clipped between a main body case 11 and a tip projection 12b of a clip 12, the 1st spring 13 supporting the clip 12 elastically supports the inserted member. If the inserted member is thick, the clip 12 is much opened and the 1st spring 13 is deformed while exceeding its elastic limit, the 2nd spring 15 supports the 1st spring 13 deformed plastically and supports the clip 12 elastically via the 1st spring 13. Thus, even if plastic deformation takes place in the 1st spring 13, the 2nd spring 15 functions instead of the spring 13, thereby allowing the clip 12 to clip the inserted member surely.

Title: Method of drilling rock bed
Inventor: HOSHINO KENZO
IPC: F24D3/02
Filed: 1986-10-07
Abstract: PURPOSE:To smoothly drill the rock bed by forming a number of holes with a slit in a planned drilling area, and causing blasting of the holes with a slit at the same time as or earlier than that of inner adjacent holes. CONSTITUTION:Holes A1, A2... are drilled in the planned drilling area in the rock bed 1, and slits 2 are cut to the holes in the circumferential direction. As S1 extends toward A2 and A3 due to the breakage of the slit 2 upon blasting, if S1, S2 and S1, S3 are connected to form a slit connecting A2, A1, A3 before P propagates beyond A2, A1, A3, its destructive wave stops within the planned drilling area. However, if the rock bed is soft, breakage can extend up to the point of P71 due to the blast at B7. In such a case, an excessive blasting will result. Since there are blast-resistant, hard spots and easy to blast, soft spots in a planned drilling area in the rock bed, a smooth drilling surface is difficult to be obtained. Therefore, by causing the blast at A1 earlier than B1, the destructive wave from B reaches after a slit was formed along the A line because the destructive wave is nearly the same whether it comes from A or B. Therefore, a smooth drilling surface can be obtained.

Abstract: PURPOSE:To accurately measure a cross-sectional shape of a pattern by irradiating laser beams on an object on stages and obtaining output of an optical detector having plural peak values and plotting the positions of the uppermost peak value. CONSTITUTION:The object 1 to be measured is placed on the DELTAZ stage 10 and the XY stage 11. Further, the positions of the stages 10 and 11 are detected by position detectors 21 and 22. A diameter of light from a laser 24 is magnified 23 and made incident on an objective 5 via a lens 3. The reflected light from the object 1 is detected by the detector 8. Then, the stage 11 is driven and stopped at a position. Then, the stage 10 is driven and the output of the detector 8 is A/D converter 14 and a peak of a signal is detected by a signal peak detector 16. When the peak value is detected, a value Zi(i=1.2) of the stage 10 is inputted to a counter 18. Afterwards, the stage 11 is again moved and the value Zi at the different position is calculated. The cross-sectional shape of the pattern can be calculated by plotting the point Zi calculated in this way.

Title: Earth discriminant device in high-voltage distribution system
Inventor: NAKADA RYOSAKU
IPC: H02H3/52
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To make the easy investigation of an earth fault point by detecting a change in phase voltage which occurs when an instantaneous earth fault occurs in a three- phase high-voltage distribution line or high-frequency signals of phase voltages of three phases and then outputting a signal to indicate the phase of the earth fault. SOLUTION: If it is assumed that an earth fault occurs in an A phase at a point P1 on a distribution line 3A, an earth current flows as a zero-phase current IO in an electrostatic capacity to earth 37 of each distribution line as shown by an arrow in the figure. The zero-phase currents IO, to flow in B-phase and C-phase healty lines are in greater part composed of high-frequency components and the polarities of the healty lines are opposite to that of the faulty line. When such an earth fault occurs, filters 18, 19a-19c in an earth discriminant device 4A installed near a connection to a bus 2 receive a signal from a zero-phase current detector 13 and a signal from a phase voltage detector 14 and then send out only the high-frequency signals IOH and VAH-VCH to level detecting circuits 20, 22a-22c and polarity discriminant circuits 21, 23a-23c.  By this method, it can be determined that the A phase of the distribution line 3A is an earth phase and thereby a faulty point can be searched for in a limited range.
