Title: Gas turbine combustor
Inventor: INOUE HIROSHI
IPC: F23C99/00
Filed: 1989-09-11
Abstract: PURPOSE:To provide a low NOx combustor of high reliability in the gas turbine combuster of premixture combustion method which has a flame stablizing enlarged flow channel section by making the flame stabilizing enlarged flow channel section non-uniform in shape in the circumferential direction. CONSTITUTION:A plurality of notches 19 are provided at an enlarged flow channel section 16 in the circumferential direction. With those notches the premixture flame that is formed at the outlet of a premixture flame that is formed at the outlet of a premixture swirler 6 is high in stability at the sections of the enlarged flow channel section 16 which have no notch because of the formation of high temperature circulation flow. On the other hand the flames are unstable, but the section on both sides in the circumferential direction where stability is high helps to form flames. As a result even if vibration develops in the section where the high temperature circulation flow is formed, it is absorbed and abated at the notch section and it is possible to reduce the pressure amplitude at the peak frequency and improve reliability.

Title: Valve operation selector device for internal-combustion engine
Inventor: KATOU MANABU
IPC: F01L1/46
Filed: 1982-12-28
Abstract: PURPOSE:To remove an air bubble as well as to prevent oil from degradation, by interconnecting a hydraulic passage to a return passage when an oil pump remains unlifted, in case of a device which selects valve operation characteristics by means of hydraulic pressure. CONSTITUTION:Each of rocker arms 6 and 7 is shifted in the axial direction of a rocker shaft 9 by hydraulic pressure to be selectively added to each of hydraulic chambers 12 and 13 and comes into contact with each of cams 4a, 5a or 4b, 5b selectively according to engine conditions. The feed of oil to these hydraulic chambers 12 and 13 takes place by means of an oil pump 17 via both a hydraulic passage 42 and a control part 21. When a plunger 19 of the pump 17 still remains unlifted, an on-off valve gear 44A has the hydraulic passage 42 interconnected through to a return passage 45, replacing oil inside the hydraulic passage 42 with a fresh one by degrees, thus not only deaerating performance in time of starting is improved but also oil degradation is prevented.

Title: Failure detector of ac thyristor switch
Inventor: FUJISHIMA YASUHIRO
IPC: H02J1/00
Filed: 1992-09-01
Abstract: PURPOSE:To make it possible to detect a failure without disconnecting a switch of an AC power source side from a failure line, by connecting an output side of a pair of detecting circuits and detecting a DC component of a current flowing between both detecting circuits. CONSTITUTION:For example, when a short-circuit failure occurs in thyristor elements Su of arm AC thyristor switch SW2 of an AC power source side 2 for backup, a half-wave short-circuit electrical radiation Is flows through the failure thyristor elements Su, and art AC current Ii flowing between neutral terminals Tn and Tn' of detecting circuits 3 and 3' is bypassed. By this, since the AC current Ii is a current containing a DC component, the DC component is detected by a DC current transformer 4. Thus, when the short-circuit failure occurs in each thyristor of the AC thyristor switch SW2 of the AC power source side 2 for backup, the failure can be surely detected without disconnecting the switch SW2 from a failure line.

Patent JP-H0396395-A (JP)
Title: Ic card
Inventor: KAMINAKA TAKESHI
IPC: B42D15/10
Filed: 1989-09-09
Abstract: PURPOSE:To reduce force applied to a semiconductor device and ensure that no cracks generate in a solder when an IC card itself is bent by adhering a sheet for preventing adhesion to an area corresponding to the semiconductor device on a panel through an adhesive. CONSTITUTION:A sheet for preventing adhesion 11 is adhered to an area corresponding to a specified IC 1 after providing an adhesive 9 on the adhesive surfaces of a front and a rear panel 7, 8. Consequently, when an IC card is loaded into or unloaded from an external device, the sheet 11 is caused to slide relative to the IC 1, if the IC card itself is bent, warping the front and rear panels 7, 8. This is because the IC 1 is not adhered to the sheet 11. Consequently, the force applied to a soldered part is minimized, if the IC card itself becomes bent, because the IC 1 is no longer pressed by the front and rear panels 7, 8.
