IPC: G03G15/04
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device without deteteriorating and destruction a laser due to the abnormality of a system. SOLUTION: The light output from the semiconductor laser 55 is detected by a photodiode 56, converted into a voltage signal by a current-voltage converter 57 and compared with reference voltage VLIN for protecting a laser by a comparator 64. The time when the signal of the light output exceeds the reference voltage VLIN is measured by a counter 66. A 1st set value being an extremely short time only for avoiding malfunction caused by noise and a 2nd set value being a comparatively long time for protection with respect to the abnormality of the system are set in the counter 66. When the counted value by the counter 66 exceeds the 1st set value, an LIM1 gets high and a transistor switch 54 is turned on to limit the current of the laser 55.  When the counted value exceeds the 2nd set value, an LIM2 gets high and the on-state of the switch 54 is maintained due to latching by a latch circuit 67 so as to continuously limit the current of the laser 55.

Title: Aluminum honeycomb panel
Inventor: ITOU YORITO
IPC: E01F8/00
Filed: 1993-11-01
Abstract: PURPOSE:To improve shape accuracy, external appearance and bonding strength. CONSTITUTION:Recessed parts 3 extended parallel with face plates 6, 7 are formed at the brazed face of a corrugated plate 2 to be part of a honeycomb core. Plural corrugated plates 2 are combined between the face plates 6, 7, and the whole is brazed. Air in cells 8 expanded by heating at the brazing time is discharged outside via communicating parts partitioned by the recessed parts 3. The inside of each cell 8 is therefore prevented from being put in a high pressure state which causes the deformation of the honeycomb core and the strength lowering of a joint part. The recessed part 3 functions also as a brazing filler material reservoir so as to prevent the degradation of external appearance of a honeycomb panel caused by the exudation of the brazing filler material.

Title: Fuel rod for nuclear fuel assembly
Inventor: SUGANO SATOSHI
IPC: G21C3/18
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a structure which will not lead to the damage to fuel rods for a nuclear reactor even if high pressure acts on them. SOLUTION: A metal cylindrical member 6 is placed between a plenum spring 5 and a fuel pellet 4. The size of the metal cylindrical member 6 is almost the same as that of the fuel pellet 4. Even if the plenum spring 5 is crushed, a cladding tube 3 will get in contact with the cylindrical member 6 at the corner of it. Since metal is softer than ceramics, the chamfering of the corner as well as the deformation of the cylindrical member 6 disables the corner from damaging the cladding tube 3. Moreover, the action of high pressure deforms the cladding tube 3 in such a way as it compresses the metal cylindrical member 6. Consequently, the fuel pellet 4 can be sealed up in the fuel cladding tube 3.

Title: Light dispersion measuring instrument
Inventor: MOCHIZUKI KIYOBUMI
IPC: H04B10/00
Filed: 1988-11-01
Abstract: PURPOSE:To measure the dispersion of 1mum band by using a nonlinear crystal for a wavelength conversion and a picosecond shutter. CONSTITUTION:A variable optical pulse of a variable frequency omega2 (wavelength lambda2 = light velocity C/frequency omega2) which is obtained from a reference optical pulse of a frequency omega1 goes into an optical fiber 3 for measuring dispersion, and thereafter, goes into a nonlinear crystal 11. As for this nonlinear crystal 11, when optical pulses of frequencies omega1, omega2 which are inputted are superposed in the nonlinear crystal 11, an intense optical pulse of a frequency (omega1+omega2) is generated as an output. Accordingly, since the frequencies omega1, omega2 are already known, a point where two pulses are superposed by taking notice of only the frequency of (omega1+omega2) and moving a light delay path 8. Subsequently, the frequency omega2 is varied by DELTAomega, and an optical pulse having a frequency of (omega2+DELTAomega) is made incident on the optical fiber 3. Next, by moving the light delay path 8 and taking notice of the frequency of (omega1+omega2+DELTAomega), a point where both the pulses are superposed is derived. From a position of the light delay path in such a case, a delay difference L/C is derived.

Title: Method for seeking optical disk device
Inventor: TAKIKITA MAMORU
IPC: G11B7/085
Filed: 1990-10-12
Abstract: PURPOSE:To previously prevent the generation of a seeking error by delaying the start of seeking for a previously determined time and evading the passage of a no-group area. CONSTITUTION:After the lapse of a fixed time from the output of a seeking instruction from a processor 15, a control part 17 outputs an objective value and a seaking signal to a driving part 18. A counter 13 counts up a zero crossing point on which a track error signal is turned from positive to negative or from negative to positive based upon a track cross pulse and sequentially outputs a counted value to the control part 17. The control part 17 compares the count value outputted from the counter 13 with the objective value, and when the count value coincides with the objective value, ends the seeking operation. Thereby, the start of seeking can be delayed only by the objective value being the previously determined time and the passage of the no-group area can be prevented. Consequently, the miscounting of tracks can be prevented, seeking accuracy can be improved and the generation of a seeking error can be previously prevented.
