Abstract: A shift lock mechanism for an automatic-transmission operating device includes a base bracket having a side wall with a window hole, a lock member rotatably supported to the outer face of the side wall of the base bracket, a hook formed with the lock member and being able to move into and out of the base bracket through the window hole, and an abutment formed on the shift lever and engaged with the hook in the height direction of the base bracket.

Abstract: A rubber composition composed of (A) a hydrocarbon rubber, (B) a vulcanizing agent and/or crosslinking agent, and (C) a hydrogenated petroleum resin having a bromine number not greater than 10 (g/100 g). The rubber composition exhibits improved processability over hydrocarbon rubber used alone but has no bad influence on the physical properties and heat resistance of its vulcanizate. It is free from any trouble involved in crosslinking with a peroxide which is often used for EPR and EPDM. Therefore, it will find general use in the rubber industry.

Abstract: A method for diagnosing hepatic carcinoma, which is characterized by enzyme-immunologically measuring the amount of collagenase inhibitor present in sera, plasmas of synovial fluids by way of a sandwich assay wherein two different monoclonal antibodies which specifically bind to different antigenic determinants of the collagenase inhibitor are used, and comparing the measured amount with that for normal subjects.

Abstract: A magnetic tape recording signal level automatic adjustment device includes: a reproduced signal level attenuator responsive to an attenuation changeover instruction for attenuating the level of a reproduced signal from a PCM audio signal reproduction device by a predetermined quantity; and an attenuation controller responsive to a sampling instruction for comparing the reproduced signal level with a reference value and outputting the attenuation changeover instruction when the reproduced signal level exceeds the reference value.

Abstract: An improved automatic reverse apparatus for a magnetic tape recorder/player of the type which employs a magnetic tape contained in a cassette provided with first and second channels. The apparatus further includes a magnetic head with head channels adapted to contact and selectively record or reproduce each of the tape channels. A pair of reels are provided for winding and rewinding the tape and a pair of capstans and pinch rollers are utilized for alternatively transferring the tape in the forward and reverse directions between the reels. The apparatus includes an operating lever which can be moved and set at two different positions to effect reversal of tape direction and switching between tape channels. A mechanical signal is generated when the tape has been fully wound upon one of the reels which in turn causes reciprocating movement of an actuator mechanism. The latter movement causes the operating lever to swing to either its first or second position.

Abstract: A battery operated, capacitor discharge type electronic, photoflash system having an electro-mechanical switching means for automatically disconnecting the battery to minimize unnecessary discharge of the battery. The system causes the battery to be disconnected at a predetermined time interval after a charge cycle has been started for a discharged main capacitor or after the main capacitor has been fully charged for a predetermined period of time.
