Title: Disk cache control system
Inventor: NAKANO ICHIRO
IPC: G06F3/06
Filed: 1990-03-12
Abstract: PURPOSE:To prevent a write-back operation carried out at the end of a job by allocating an alternate block to a data block set on a disk having a medium error and writing data into the alternate block at the time of a write-accessing the disk. CONSTITUTION:A disk 10 is provided with a medium error detection means 12 which detects the occurrence of a medium error and an alternate block allocation means 13 which allocates an alternate block to a data block having a medium error. Thus the alternate block is allocated to the data block set on the disk 10 that has a medium error if this error occurs at the time of a write-accessing. Thus the medium error is not reported to a CPU at the time of write-back processing a disk cache. Therefore no write-back instruction is required in a job closing state of software.

Title: Device for spreading fine particle
Inventor: OGUSHI TSUTOMU
IPC: G02F1/1339
Filed: 1989-03-13
Abstract: PURPOSE:To prevent fine particles from forming aggregations by dividing a fine particle diffusion chamber by means of an upper and lower filter to form a sample chamber, providing a gas pipe for spreading fine particles in the sample chamber, and applying antistatic treatment to the interior thereof. CONSTITUTION:A substrate 16 comprised of a glass plate is placed on a screen 13, while fine particles are filled in a sample plate 9, whereby gases are blown off from a bomb 20 through gas lines 7, 8 into a spreading chamber 2. As a result, the sample in the plate 9 is spread instantaneously in a diffusion chamber 1 and caused to flow upwardly through a connecting line 3 so as to be spread in the spreading chamber 2. The fine particles in a state of monodisperse having blown into the chamber 2 are rapidly decelerated at the spreading port 14 of the line 3, so that they tend to stick to said port, however, they are prevented from sticking thereto by the gas blowing from a cleaning gas pipe 15. In this manner, the particles are spread evenly over the substrate in a mono-dispersed state.

CONSTITUTION:A response delay detecting means 105 is provided with a deflection detecting part 105A detecting the deflection corresponding to the changing amount of the relative positions when an irradiating part 100 is relatively shifted along the marginal part of a substrate 101 while driving a relative shifting means 102 so as to specify the relative positions in the exposure width direction of the substrate 101 and the irradiating part 100 as well as a delay data detecting part 105B detecting the response delay data according to the detected deflection. This delay data detecting part 105B computes the response delay time of the relative shifting means 102 according to the deflection. Finally, a reflecting means 106 suppresses the response delay in the exposure time by deflecting the relative relation between the driving amount of the driving amount data and the exposure position of the substrate by the amount equivalent to twice amount of the computed response delay time.

IPC: H04R9/12
Filed: 1979-05-17
Abstract: PURPOSE:To improve the quality and to increase the durability through the improvement of electric generating efficiency and sound effect, by freely rotating a coil in the gap of magnetic poles by means of the torque from a coil driving piece displaced in response to the movement of a stylus. CONSTITUTION:The movement of a stylus 14 is delivered to a cunti-lever 15 to activate a coil driving piece 16 attached at the tail end of the lever. In this case, in each magnetic pole gap consisting of a magnet 20 and a yoke 21, a coil winding frame 19 supported with a pivot 17 and each coil 18 wound on the coil winding frame 19 are induced electricity, since they are moved in the magnetic pole gap through the torque of the coil driving piece 16 taking the pivot 17 as a center, and the current corresponding to the displacement flows to the coils 18. Accordingly, since all the coils 18 are located in the magnetic pole gap, the efficiency of electricity generation increases without increasing the effective mass of the cunti-lever 15, hardly causing resonance phenomenon to the oscillating system.

Title: Ignition device

IPC: F23Q3/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To protect an ignition device against overvoltage. SOLUTION: An overvoltage protector circuit 2 is provided which utilizes Zener breakdown of a Zener diode Zd. For example, when to AC 100 V specification an AC 200 V power supply is connected, electric potential at a connection point P1 between resistance R3 and resistance R4 is raised. When the electric potential at the connection point P1 reaches Zener voltage of the Zener diode Zd, a current iz flows through a passage: resistance R3 → Zener diode Zd →resistance R6 → a base of a subtransistor Q2 whereby the subtransistor Q2 is switched on. Hereby, a main transistor Q1 is forcedly made off, a collector current I1 to the main transistor Q1 is interrupted, and the main transistor Q1 is prevented from being destroyed owing to a large collector current.

Abstract: PROBLEM TO BE SOLVED: To improve the quality of image provided by processing, based on a detected area by detecting the boundary area between a character/drawing area in an image and the other image area. SOLUTION: A character/drawing/halftone detection part 2023 detects character, drawing and halftone areas, and a dot area detection part 2024 detects a dot area. In an image related to a signal PICT-ISO as the OR of detecting signals BINGRA and AMI at both the detecting parts, a non-detected area exists in the contour area between the dot area and the character area. Based on the isolation degree for white pixel, a redetection part 2027 discriminates whether or not the concerned pixel belongs to the non-detected area, and based on the result, the non-detected area is detected. Thus, the signal PICT-ISO is corrected and a proper detecting signal PICT is generated.

Filed: 1979-05-21
Abstract: PURPOSE: To trace easily and accurately information tracks recorded by the optical system and so on, by zugzagging bits minutely during a certain period and by avoiding superposition onto the zigzagging period of adjacent tracks.  
     CONSTITUTION: When frame pulse FP is inputted to FF25, FF25 repeats "0" and "1" alternately each time disc 10 rotates once, and this output is inputted to one end of exclusive OR circuit 26, however, output 7' from frequency dividing circuit 23 is inputted to the other end, and therefore, the phase of output signal 7 of circuit 26 is inverted at the N-th rotation for the (N+1)-th rotation. This signal 7 is used as the gate signal of gate circuit 5; and when the output signal of frequency dividing circuit 22 is inputted to circuit 5, output signal 12 has phases, where the signal of frequency f 1  appears at the N-th rotation and the (N+1)-th rotation, shifted alternately. When a minute spot on disc 10 is deflected in the radius direction slightly by optical deflector 4 according to this signal 12, tracks having zigzag period which are discontinuous in the rotation direction and are not superposed onto them of adjacent tracks in the radius direction are formed on the disc. Consequently, information recording tracks can be traced accurately.
