Title: Bulb type fluorescent lamp
Inventor: SHIRATA NOBUYA
IPC: H05B41/24
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent thermal deformation or thermal destruction of a fluorescent tube even in its life final stage by providing an overcurrent protection element broken within a predetermined time longer than a time prescribed for transition of the fluorescent tube to arc discharge and shorter than a time expecting breakage of the tube in its life final stage. SOLUTION: By means of secondary voltage continuously applied to a fluorescent tube by means of a lighting circuit until the tube in starting is shifted to arc discharge, an overcurrent fuse 5 is broken within a predetermined time, which is longer than a time prescribed for transition of the arc tube to are discharge and shorter than a time expecting breakage of the tube in its life final stage, and the arc tube is cut off from the lighting circuit. Therefore, in the final stage of a life of the tube, current supply is secured for a time longer than a transition time to arc discharge, and the lamp can be tuned on if certain lighting ability remains in the tube. The overcurrent fuse 5 is broken within a time shorter than a time in which breakage of the tube is expected, so that breakage of the tube can be prevented.

Title: Illuminating device
Inventor: KOMATA KATSURA
IPC: G02B6/00
Filed: 1990-07-13
Abstract: PURPOSE:To obtain an illuminating device which is thin and gives excellent visibility by directly enveloping a light emitting element in a light transmission body and forming a part from the neighborhood of the light emitting element to the neighborhood of a key button as an integrated substance. CONSTITUTION:The LED element 5 is directly fitted on a printed substrate 1 and the light transmission body 11 is shaped by directly molding the LED element 5 by resin. In an illuminated type membrane switch constituted in such a way, light emitted from the element 5 is transmitted through the light transmission body 11 and transmitted to the end surface of the key button 4 from the left side surface of the light transmission body 11 in a figure. Then, it is guided to the upper surface of the key button 4. Thus, since the element 5 is directly enveloped in the light transmission body 11 and the part from the neighborhood of the element 5 to the neighborhood of an irradiation display part is formed as the integrated substance, there is not a joint on the transmitting path of the light. As the result, the light of the light emitting element 5 is efficiently guided to the illuminated display part.

Title: Optical recording and reproducing device
Inventor: OISHI MASAMI
IPC: G11B7/00
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To rapidly and exactly execute the specification of the final recording position of a DRAW type recording medium by specifying the final recording position in accordance with the time information of a final error correction code ECC block and deciding the presence or absence of recording error. SOLUTION: The optical recording medium 13 is reproduced and an interruption of an RF signal is detected by an RF detection circuit 5 to define the RF final position. The timing from the point of the time that an ECC block sink signal is detected until the RF signal is interrupted is counted by a timer 6 and the final position of the previous recording is determined by the address of the ECC block sink stored in the memory in a control circuit 7 and the timer value. The presence or absence of the recording error is judged in the position where the previous recording ends by whether the link flag in the final sector of the final ECC block stands or not. If the flag 1 stand and if the timer value exists within the range assigned to an overwrite area, judgment is made that the recording ends normally and the position is determined as the final recording position.

Title: Overcurrent passage indicator
Inventor: TAKAOKA NAOTOSHI
IPC: G01R19/15
Filed: 1980-12-27
Abstract: PURPOSE:To eliminate troubles at the driver section by obtaining a driving force for detecting an overcurrent utilizing that an attraction force works between a fixed core and a mobile core mounted surrounding a wire when an overcurrent flows thereto through the wire. CONSTITUTION:When a constant current flows through a wire 17 equipped with an overcurrent passage indicator, gravity working on a mobile iron piece 10 and members connected thereto is larger than an attraction force between a fixed core 21 and them. The mobile iron piece is in contact with the top of a retaining plate 4, which enables the confirming of the existence of a butterfly valve 13 or the like in a cylinder chamber 7 through a transparent plate 6 from outside. When an overcurrent flows through the fixed core 21, it attracts the mobile iron piece 10 so that the butterfly valve 13 moves upward against a small viscostic resistance of an oil 8 in the cylinder chamber 7. As a result, the oil 8 enters between the butterfly valve 13 and the transparent plate 6 enabling the confirming of the oil 8 from outside. This indicates the flowing of the overcurrent through the wire 17. Troubles can be reduced with no complicated construction.

Filed: 1990-07-18
Abstract: PURPOSE:To obtain a very simple circuit constitution and to provide a circuit constitution without latch-up with only a slight increase of the area by connecting the base of a parasitic P-N-P transistor to the emitter or to a part of a resistor which is connected to the emitter. CONSTITUTION:The base of a parasitic P-N-P transistor 11 is connected to the electrode of a p-type resistor region 2 on the high potential side. Therefore, the base potential becomes higher than the emitter potential, and the parasitic P-N-P transistor 11 is OFF. Thus, a current does not flow through a resistor 12. Since the potential of a p-type isolating region 6 of a parasitic N-P-N transistor is low, the N-P-N transistor 13 is also OFF. Therefore, the current does not flow, and latch-up does not occur.
