Title: Luminescent clock
Inventor: AOKI SHIGEHIKO
IPC: H05B44/00
Filed: 1994-12-20
Abstract: PURPOSE: To provide a luminescent clock attaining a proper visual effect. CONSTITUTION: An EL element 1 shows the luminescent color corresponding to the frequency of the drive AC voltage generated by a driving circuit 2. The driving circuit 2 is constituted of an astable multivibrator 3 generating the oscillation output corresponding to a connected resistance value and a transformer L fed with electrical power from a transistor to driven by the oscillation output. The frequency of the driving AC voltage generated by the secondary coil 12 of the transformer L coincides with the frequency of the oscillation output of the astable multivibrator 3. The resistance value is periodically switched by a resistance changing circuit 4 to change the oscillation frequency, and the luminescent color is also switched. The dazzling and bothering impression caused when the brightness of the EL element 1 is excessively switched is not given to a user.  The switching cycle is accelerated by a selecting circuit 7 as the present time counted by a time control circuit 8 approaches the alarm time, and a sufficient visual effect is obtained.

IPC: B41J29/38
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To previously prevent an error from being erroneously detected when AC input is unexpectedly interrupted in an image forming device. SOLUTION: A power source unit 10 outputs a DC voltage based on the AC input. The AC input is utilized for driving a fixing heater 21. An ASIC 35 is driven by the DV voltage, and detects a heater related error. The unit 10 has a circuit 12 detecting the zerocross of the AC input. A CPU 31 is driven by the AC voltage, and detects the interruption of the AC input based on a zerocross signal. When the error is detected based on the output of the ASIC 35. Whether or not the AC input is in an interrupting condition is detected; and when the AC input is interrupted, error is ignored without the performance of error processing with respect to the error.

Filed: 1987-12-17
Abstract: PURPOSE:To enable the initial absorption force of a movable contact to increase and the breaking time to shorten by impactfully applying the magnetic attractive force of a movable iron core to which a latch mechanism is released to a movable contact and increasing the initial opening speed of the movable contact by linking up with the spring force of a quick-break spring. CONSTITUTION:When a main circuit current reaches the detecting level of abnormal current, a movable iron core 8 is attracted by making a pin 9 as fulcrum, a latch mechanism is released to disengage the roller 14 of a movable contact 3, the movable contact 3 is opened through a quick-break spring 16 by making a pin 15 as fulcrum. All this while, arc current flows between a fixed contact 2 and the movable contact 3, so the magnetic attraction force acts on the movable iron core 8. This acting force is applied to the movable contact 3 until a gap g between a fixed iron core 7 and the movable iron core 8 becomes zero through a impactor 17 which is arranged opposed to the movable contact 3 on the top side of the movable iron core 8 and has a predetermined length. Thereby, the movable contact 3 can obtain a high initial opening speed by linking up with the opening force of the quick-break spring 16.

Title: Charged particle beam blanking device
Inventor: ISOBE MORIYUKI
IPC: H01J37/09
Filed: 1988-12-16
Abstract: PURPOSE:To prevent displacement of the image focusing point of beams on a target during beam blanking by allowing the virtual deflection center of the beams obtained by first- and second-stage deflection means to coincide with the objective point. CONSTITUTION:A beam receptor 3 is installed at the objective point C1 of image focusing beams on a target, and beams deflecting means 1, 2 are provided in front of and behind the beams receptor 3.

Filed: 1991-12-03
Abstract: PURPOSE:To enhance an efficiency of a memory test and to shorten a testing time by setting a voltage to be applied to a memory to be tested to a specific level or lower, extracting a bit to become defective first and using an address of the defective bit as a base address. CONSTITUTION:A specified voltage is applied to a memory 21 in a state that the memory 21 to be tested is connected to a terminal of a memory tester. Then, '0' or '1' is written in all bits of the memory 21, read after a predetermined time has elapsed, and checked. Thus, whether there is a bit inversion in written data or not can be checked. If there is no defective bit as a result of the check, a memory voltage is lowered, and this process is repeated. If there is the defective bit, a defective address is stored, and a process is repeated for an inverted pattern. When the inverted pattern is all tested, a test starting address is set to the defective address, and various tests are conducted. Thus, an efficient memory test can be executed to shorten a testing time.
