Abstract: PURPOSE:To reduce the image error due to magnifying power distortion by a method wherein magnifying power adjusting lenses with low power are displaceably arranged on an optical path within a projection optical system projecting a negative image on an object through projecting lenses in the direc tion of optical path within said projection optical system. CONSTITUTION:Two each of magnifying power adjusting lenses 43, 44 are arranged between a projection lens 41 and an image forming surface 42. On lens 43 is plane on the projection lens side and the other side is a concave lens while the other lens 44 is plane on the image forming surface side and the other side is convex lens i.e. the curvatures of opposing concave and convex lenses are selected properly to make the magnifying power equivalent so that both lenses may maintain pupplementary relation with each other. Through these procedures, the relative distance between both lenses 43 and 44 can be changed to make the main light 45 intersect with the image forming surface 42 resultantly maintaining the parallelism of main light 45 with the optical path 46 to make the magnifying power variable.

Title: Transformer protective device
Inventor: SAITO YOSHIAKI
IPC: H02H7/055
Filed: 1994-07-26
Abstract: PURPOSE:To prevent abnormality detecting sensitivity of a transformer protective device against an on-load tap changing transformer by correcting the unmatching amount generated due to the relation between input information and output information by changing the tap of the transformer. CONSTITUTION:In an on-load tap changing transformer 1, a vector-difference current DELTAI does not become zero, but becomes + or -i2.n0/100 even when matching is established by switching the tap of the transformer 1 to a midpoint switching tap 6a, because the tap position of the transformer 1 is moved and the transformer ratio of the transformer is changed by + or -n%. Therefore, a correction circuit 11 multiplies an electric current i2 by K to the value corresponding to the tap position of the transformer 1 and outputs the value to a current differential relay 9. When a fault occurs in the transformer 1 and the magnitude of the vector difference current DELTAI becomes larger than the xsi of the current i2 flowing between a current transformer output adjusting tap 8 and the relay 9 in a state where the magnitude of the current DELTAI is matched, the relay 9 detects the fault and performs protecting operations. As a result, the deterioration of the abnormality detecting sensitivity of a transformer protecting device can be prevented.

Title: Recording method and recording apparatus using the method
Inventor: SHIMODA JUNJI
IPC: B41J2/18
Filed: 1995-07-11
Abstract: PURPOSE: To record images of good quality without causing improper discharging even in the long-time continuous recording operation by providing a comparison process wherein a count of ink drops accumulated in an accumulation process or a representative value is compared with a predetermined threshold value, and a control process wherein sucking is recovered in accordance with the comparison result. CONSTITUTION: A counted value of recording dots A is added to a value of the total recording dots B stored in an EEPROM 17. The added value is set as a new value of the total recording dots B. The B is compared with a predetermined threshold value C. When B<C is held, it is judged not to be a case wherein dissolved air bubbles are left stagnant in the continuous recording operation to obstruct proper discharging of recording liquid drops. Accordingly, the process is returned and the recording operation is continued. On the other hand, if B>=C is held, it is judged as the case wherein the dissolved air bubbles are stagnant in the continuous recording operation and the recording liquid drops are not discharged properly. The process is returned to perform a suction recovery operation.  Even when the recording operation is continuously carried out for a long time, it is prevented that the air bubbles remain in a common liquid chamber within a recording head to cause improper discharging of recording liquid drops.

Title: Magnetic tape reproducing device
Inventor: KAWASHIMA OSAMU
IPC: G11B27/28
Filed: 1994-07-27
Abstract: PURPOSE:To improve precision in searching a program recorded on a tape in the search operation. CONSTITUTION:At the time of search operation in a fast forward mode, the tape speed detection means 6 detects the running speed of the magnetic tape 1 during the fast forward operation. When the intermusic detection means 2 detects an intermusic between the programs recorded on the magnetic tape 1 during the fast forward operation, the arithmetic means 7 computes the required delay time from the speed of the magnetic tape. Although, in accordance with the detection of an intermusic, the control means 3 outputs an instruction to suspend the fast forward operation, the instruction for suspension is transmitted to the mechanism control means 4 after the instruction is delayed by a delay time calculated by the arithmetic means 7 using the delay means 8. This always allows the magnetic tape to be suspended at a specified position against the intermusic position recorded on the magnetic tape, and accordingly, a precise program searching is made since an appropriate arithmetic processing performed by the arithmetic means 7 can vary the delay time depending on the tape speed at the time of suspension.
