Title: Image restoring method
Inventor: MATSUBA IKUO
IPC: G06T5/00
Filed: 1986-03-13
Abstract: PURPOSE:To make edge detection as well as noise elimination possible by using an image energy in which the differential of the every function related to the gray scale of each picture element consists of Laplacian and a term that is proportional to the square of noise, and adjusting the gray scale of each picture element so that the probability determined by the image energy is maximum in probabilistic processing. CONSTITUTION:Intermediate restoration image data in a file obtained by P-number repeats is read in, and a parameter T(P+1) related to temperature is set. Next, m- number processing object picture elements are extracted at intervals of two picture elements in an (i) direction, and degrees Xi+1<(>P<)> of gray of all other picture elements are fixed. With respect to the extracted object picture element group, a degree X'i+1P<+1)> of gray which minimized an image energy quantity E is obtained. A change decision reference (q) is calculated, and thereafter, a uniform random number eta is generated, and (q) and eta are compared with each other. X'i+1(P+1) is adopted as Xi+1<(>P<+1)> in case of q>=eta, but Xi+1<(>P<)> is adopted as Xi+1<(>P<+1)> as it is in case of q<eta. After the processing of m-number object picture elements, another m-number picture element g group is processed, and this processing is repeated until the processing of all picture elements is terminated.

Title: Audio disk player and tape recorder
Inventor: YAMADA TOMOYASU
IPC: G11B19/02
Filed: 1988-03-09
Abstract: PURPOSE:To record music reproduced from a disk to plural cassette halves in discrimination with each other by securing such constitution where the cassette halves are exchanged for sound recording via an auto-change mechanism with input of a synchronizing signal. CONSTITUTION:The cassette halves are taken into a cassette driving mechanism part 4 in each step and sound recording is carried out. At the same time, the presence/absence of a synchronizing signal received from a CD player is monitored at recording of each step. If the presence of the synchronizing signal is confirmed, the recording action is stopped for the cassette half under recording in the relevant step and an index is incremented. Thus the synchronizing signal is outputted every time the disks are exchanged at the CD player side. While the cassette halves are exchanged at the tape recorder side with detection of the synchronizing signal. As a result, the music of each disk are recorded on each prescribed cassette half in discrimination with each other based on each program.

Title: Pulse gas laser exciting circuit
Inventor: ITO SHINJI
IPC: H01S3/097
Filed: 1985-03-18
Abstract: PURPOSE:To enable a high voltage rising quickly to be applied between main discharging electrodes for obtaining a large output with a high efficiency, and to increase the life of a switching circuit, by providing a closed circuit for transferring the energy stored in a charging capacitor to peaking capacitors. CONSTITUTION:First and second peaking capacitors 5 and 6 are connected in parallel to main discharging electrodes 1 and 2 of a pulse gas laser. When energy is transferred from a charging capacitor 3 to the capacitors 5 and 6, a magnetic switch (saturable inductance) 9 acts as an inductance much larger than first and second inductances 7 and 8 so that the energy stored in the charging capacitor 3 is transferred slowly to the first and second capacitors 5 and 6. Consequently, the rise of electric current flowing through a switching circuit 4 is retarded, and the peak value is thereby decreased. The passive switching circuit 4 is provided with a low inductance so that a high voltage which is quick to rise and twice or three times higher than the discharging voltage Vo of the charging capacitor 3 is applied between the main discharging electrodes 1 and 2.

Title: Measurement of insulator contamination
Inventor: KURI TAKAYOSHI
IPC: G01R31/12
Filed: 1989-03-07
Abstract: PURPOSE:To improve a measurement accuracy for cumulative arithmetic contamination amount by comparatively discriminating the contamination amount on the N-th actual measurement and the arithmetic contamination amount in the preceding time for the same measuring part. CONSTITUTION:The contamination amount on the N-th actual measurement and the arithmetic contamination amount in the preceding time for the same measuring part are comparatively discriminated by an arithmetic device, and when the former is larger than the latter or equal thereto, the difference between both amounts is added to the cumulative arithmetic contamination amount to make the N-th cumulative arithmetic contamination amount. If the former is smaller than the latter, the ratio of both amounts is multiplied by the preceding cumulative arithmetic contamination amount to make the N-th cumulative arithmetic contamination amount. Then an increasing or decreasing tendency of the contamination amount in the same exposed period is decided by measuring the plural parts to be measured in order. The measurement accuracy for the cumulative arithmetic contamination amount is thereby improved. When a corrective arithmetic contamination amount which is obtained from the ratio of a residual amount and the contamination amount after the washing, is added, the measurement accuracy is further improved.
