Title: Driving circuit for semiconductor laser
Inventor: TAKASAGO MASAHIRO
IPC: H01S5/042
Filed: 1991-03-20
Abstract: PURPOSE:To protect a semiconductor laser and recorded information against breakdown, which may occur due to slow response when the quantity of emitted light is compared with some threshold in order to detect abnormal light emission, by detecting abnormal light emission through a semiconductor laser drive circuit for an apparatus which records information with a semiconductor laser beam and then interrupting emission of light. CONSTITUTION:A current detecting circuit 13 detects laser driving current 21 and a current variation detecting circuit 10 detects abrupt variation of abnormal light emission driving current 21 per unit time. When thus detected variation rate is higher than a predetermined value, a driving current bypass circuit 12 prevents the driving current 21 from flowing through a laser thus preventing abnormal light emission. Any loop signal may be employed in the current detection through a closed loop circuit for sustaining the laser beam at substantially constant level. When emission of laser beam is interrupted based on the rising of driving signal for semiconductor laser, abnormal emission of laser beam is prevented resulting in protection of the semiconductor laser and recorded information against breakdown.

Title: Tester for stress corrosion cracking
Inventor: URAGAMI KOUICHI
IPC: G01N3/12
Filed: 1982-04-06
Abstract: PURPOSE:To subject a tubular test member to a test for stress corrosion cracking in an as-worked state in the manufacture by welding the opening of said member to the opening of a test cylinder provided with a pressure conduit pipe, sealing the other opening hermetically, containing the assembly in a vessel and forcing pressurizing corrosive liquid therein. CONSTITUTION:A blind plate 2 is mounted to the end part 1b of a member 1 consisting of a pipe material 1 to seal said part hermetically, and the member is contained in a test cylinder 3 in the stage of testing said member. The opening end 3a of the cylinder 3 and the end part 1a of the member 1 are joined airtightly by welding 4. Many pieces of such cylinders 3 are manufactured and are placed on the rack in a vessel 6. A pressure conduit pipe 5 is drawn out from each draw-out pipe 10. When corrosive liquid is forced into the vessel through an introducing pipe after a cover 6b is closed, the liquid is filled in the vessel 6 and in the member 1 as well. The outside surface of the member 1 is maintained under the atmospheric pressure through the pipe 5. When a damage arises in the member 1 owing to corrosion, the corrosive liquid penetrates in the member and the pressure is transmitted through the pipe 5 to the outside and is detected with a pressure gage. Thus the test for stress corrosion is made possible in the as- worked state in the manufacture.

IPC: G06F17/50
Filed: 1990-03-08
Abstract: PURPOSE:To accurately measure the capacity of a vessel without using a free three-dimensional curved surface by calculating a cross sectional area at an arbitrary hight from cross sectional numerical data at the height, integrating the calculated cross sectional area over all heights and calculating the capacity of the vessel, CONSTITUTION:Over the full height of the vessel, the dimensions of width and thickness are calculated from front and side view at an interval of the fixed pitch and next, the cross sectional numerical data at the specified arbitrary height is calculated from the numerical data of the already known cross sectional figure by executing interpolation based on the dimension of the width or thickness at the height of the already known cross sectional figure and the data of the width or thickness at the arbitrary height. Further, the cross sectional area at the height is calculated from the cross sectional numerical data at this calculated arbitrary height, and integrated over the full height of the vessel so as to output the capacity value of the vessel. Thus, without using the free three-dimensional curved surface, the capacity of the vessel can be accurately and easily measured.

Title: Dynamic damper
Inventor: ODA TAKASHI
IPC: B62D24/02
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the loose-out of a damper mass without increasing the number of part items. SOLUTION: A pair of brackets 12, 12 are fixed to car body frames 11a, 11b by bolts 13 and nuts 14. A support pin 22 is pressed into both ends of a damper mass 20 for fixation. A tip of each support pin 22 is connected to the bracket 12 through a rubber elastic body 23. A tip of the bolt 13 is arranged at a position opposite to an end surface of the support pin 22 on the extension of the support pin 22. Even in the case where the rubber elastic body 23 is broken and engagement of the damper mass 20 with the support pin 22 is removed, since the axial displacement of the support pin 22 is regulated by the tip of the bolt 13, perfect loose-out of the support pin 22 from the damper mass 20 is prevented. With this structure, the damper mass 20 is surely supported on the brackets 12 through the support pin 22.

Inventor: GOTO KEIZO
IPC: B60H1/00
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of air to the outside of a case by keeping a state that a packing is compressed. SOLUTION: An opening part 4 through which a heater core 5 is inserted is formed in a case and a rib 6 is erected on the edge part of the opening part 4. A packing 5a formed of a porous material is located at a part being a gap between the inner end face 4a of the opening part 4 and a heater core 5 when the heater core is inserted in the case. The heater core 5 inserted in the case 1 is brought into a state that the heater core is nipped from both sides by a bracket 9 through ribs 6. Thereby, a distance between the inner end face 4a of the opening part 4 and the heater core 5 is rendered constant and the packing 5a keeps a compressed state. Thus, a flow of air about to flow through a gap between the heater core 5 and the inner end face 4a of the opening part 4 is interrupted and leakage of air to the outside of a case is prevented from occurring.

Title: Switching power source
Inventor: MEGURO TAKESHI
IPC: H02M3/28
Filed: 1991-03-01
Abstract: PURPOSE:To provide specifications of a diode having a low breakdown strength and a low forward voltage drop as a rectifying diode disposed on the secondary side in a switching power source having a magnetic amplifier on the secondary side. CONSTITUTION:A saturable reactor MA1, a rectifying diode D1, a coil L and a capacitor C for constituting a magnetic amplifier are connected in series with a secondary side winding L2 of a transformer T. A smoothing circuit is formed of the coil L and the capacitor C, and a commutating diode D2 is connected in parallel with the smoothing circuit. A load R is connected to output terminals of both ends of the capacitor C. In this circuit, since a voltage between the terminals of a secondary winding at the time of resetting is equal to the sum of the voltage between the terminals of the diode and the voltage between the terminals of the reactor, a backward voltage to be applied to the diode is smaller by a voltage drop of the reactor. Accordingly, the diode having a small breakdown strength can be used.
