Abstract: An underwater breathing apparatus is provided for delivering air to a submerged diver. A manual pump (17) supplies air under pressure to a reservoir bag (12) for delivery to a diver through an air hose (24,29,31). Alternatively, the reservoir bag can be further connected by an air hose to a floatable variable-pressure reservoir bag (28) that delivers air through an air hose (29,31) to a submerged diver. In order to constantly maintain the air pressure in the reservoir bag in a preselected range, a pressure gauge (40) is provided for the pump operator, who then pumps selectively to maintain the proper air pressure. The diver wears a breathing means having a flow restrictor/shut-off valve, a one-way inlet valve (32), and a one-way exhaust valve (34) for exhalation. Additionally, an electric pump may be used either to replace the manual pump or as a back-up thereto.

Abstract: In a starter system for an internal combustion engine using a planetary reduction gear unit, the internal gear of the planetary reduction gear unit, the center bracket accommodating the internal gear and the pinion cover are joined together so as not to rotate relative to one another by using radial projections provided in the outer circumferential surface of the internal gear which are passed through openings provided in the center bracket and received by associated recesses provided in the pinion cover. The three members are thus prevented from rotating relative to one another with a simple structure which is also easy to assemble. The projection of the internal gear may also be used for securing an annular seal member interposed between an axial end surface of the internal gear and the corresponding shoulder surface of the center bracket.

Abstract: L'invention se rapporte à un procédé et à un appareil servant à déterminer la position exacte d'une cible (C) par rapport à une référence (O) aux coordonées connues. L'appareil comprend une source de rayonnement (30) servant à former une image d'une cible (C), cette image étant reçue par un dispositif récepteur (24) placé au-delà de la cible. Un dispositif formant un masque (40), qui est interposé entre le dispositif récepteur et la source de rayonnement, comporte au moins un organe de localisation (R1, R2) de position connue par rapport à un point de référence et sert à former une image dans le rayonnement de formation d'image, un organe étant également prévu pour déplacer la source de rayonnement dans trois dimensions, au moins entre deux positions angulaires différentes (S1, S2), ce qui entraîne un déplacement des coordonnées de deux images différentes de la cible obtenues à partir de deux positions angulaires différentes de la source. Cette invention permet ainsi de déterminer la position exacte d'une cible avec un degré de précision trés élevé, grâce à un procédé qui est simple et qui limite la dose du rayonnement. La cible peut être une cellule, un calcul ou un tissu osseux devant être traité.

Abstract: An output circuit of a sense amplifier for amplifying signals read out from a memory holds its output signals at predetermined levels stably in a state that equalizing pulses are being generated. Differential amplifiers (36a, 36b) amplify a pair of complementary signals read out from the memory. The output terminals of these differential amplifiers (36a, 36b) are connected to latch circuits (13, 14) via clocked inverter circuits (11, 12) and connected to transfer gates (N1, N2) controlled by equalizing pulses (EQ, EQ). Since the clocked inverter circuits (11, 12) have high output impedance while the equalizing pulses are being generated, the signals held at the latch circuits (13, 14) do not change.
