Title: Hardware stacking device
Inventor: YOKOTA MINORU
IPC: G06F9/34
Filed: 1982-04-30
Abstract: PURPOSE:To attain a conventional and high speed device with a good cost/ performance for any application mode, by returning the content of a saved stack memory preceedingly and using the content as if an infinite length of stack memory were provided. CONSTITUTION:The address 0 of the stack memory 1 is stored in a main storage address indicated by an address register 3. When a stack counter 2 reaches 15, the address 1 of the stack memory 1 is saved. At each production of PUSH, the content ahead by two addresses from the location of the stack memory 1 indicated by the stack counter 2 is saved in advance at all times, allowing to permit the cyclic use of the memory 1. Since the saving/restoration of the memory 1 is done asynchronizingly against the operation of the counter 2 with a control circuit, until the value of the counter 2 reaches the value of the address register 3, it is possible to follow PUSH and POP-UP in the access time of the stack memory 1.

A glass substrate holding jig 7 grasps and holds the oblique side (a) of the glass substrate 6 vertically and is able to carry it in this state. The glass substrate 6 is put in a cassette which is taller than the glass substrate 6, which is drawn out of the cassette by the glass substrate holding jig 7 by grasping the part of the glass substrate 6 projecting from the cassette. Thus, the trapezoid glass substrate 6 can be stored vertically and carried vertically.

Title: Memory backup device
Inventor: YASUDA AKIRA
IPC: G06F11/00
Filed: 1980-05-31
Abstract: PURPOSE:To prevent backup information from being destoryed with simple constitution by inhibiting a control signal from being applied from a CPU to a floppy disk through a monostable multivibrator, AND circuit, etc., for a required period on detecting a drop in power voltage. CONSTITUTION:When a power source detecting circuit 4 detects the power voltage  of a power source circuit 9 dropping to some extent, a monostable multivibrator 5  is triggered to generate a low-level output for a prescribed period and then a control  signal applied from a CPU1 to a floppy disk device 3 via AND gates 6 and 7 is at a low level. Therfore, no erroneous control signal is applied from the CPU in the  period when a power source decreasing in voltage with some time constant and  releasing is unstable, so the simple constitution prevents backup information in the  floppy disk from being destroyed.

Title: Radio wave interference device
Inventor: TAKIGUCHI NOBORU
IPC: G01S7/38
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To continue an effective interference effect, even if a missile approaches. SOLUTION: The distance information of a missile is inputted to an operator 20 via a remote control receiver 19 of a radio wave interference shot. In this case, a distance with J(an interference wave)/S(a radar reflection wave) being equal to 1 is calculated, and the output of a pulse generation circuit 15 is switched to a continuous wave when the distance is reached, thus performing continuous wave interference. An HOJ (home on jamming) that is an interference source tracking function that the missile has is induced by the continuous wave interferene, thus an effective interference effect is continued, even if J/S is equal or less than 1.

Abstract: PROBLEM TO BE SOLVED: To increase a speed of binarization printing and to enhance accuracy of gradation printing. SOLUTION: An ink jet head 13 wherein multiple ink chambers each having a partition made of a piezoelectric material are arranged is controlled to be moved in a direction of arrangement of the ink chambers. At that time, a recording paper 5 is wound around a rotation drum 2 which is rotated in a direction perpendicular to the direction of arrangement of the ink chambers. A voltage is applied across electrodes of an ink chamber adjacent to electrodes of an ink chamber which should eject an ink drop to create a pressure change in the ink chamber so that the ink drop is ejected from the ink ejection nozzle. The printing is performed by a pitch which is smaller than a pitch of the ink ejection nozzles. In the ink jet head, the ink nozzles each having a large diameter and the ink nozzles each having a small diameter are alternately arranged.  The binarization printing is performed by ejecting the ink drop from the ink ejection nozzle having the large diameter and the gradation printing is performed by ejecting the ink drop from the ink ejection nozzle having the small diameter.

Filed: 1986-03-31
Abstract: PURPOSE:To obtain a variable wavelength light source having narrow spectral width by inputting the output of a photodetector to control a resonator so that the resonance frequency of a Fabry-Perot resonator follows with respect to the output frequency of a semiconductor laser. CONSTITUTION:An output light from a semiconductor laser l FM-modulated by a frequency fm by an FM modulation signal source 7 is incident to one reflecting mirror 31 of a Fabry-Perot resonator 3, emitted from the other reflecting mirror 32 to be incident to a photodetector 4. The output of the photodetector 4 is input to the lock-in amplifier 51 of a controller 5, and rectified synchronously with frequency 2fm. A PZT element 52 is driven by the output of the amplifier 51 to control the mirror 32 to a point where the output of the amplifier 51 becomes '0'. A phase noise component contained in the incident light from the laser 1 is converted to an amplified modulation signal (f) at the bending point (h) of resonance characteristic (d), negatively fed back through a wide band amplifier 6 to the injected current of the laser 1 to be suppressed. As a result, a narrow spectrum is performed in each frequency nu swept by a sweep signal source 8.
