Title: Opto-electronic integrated circuit and method of manufacturing the same
Inventor: DOGUCHI KENTARO
IPC: H01L31/0224
Filed: 1994-07-04
Abstract: In an opto-electronic integrated circuit of the present invention, in a first surface region of a semiconductor substrate, a pin-type photodiode is constituted on the basis of a photodiode layer formed on a first transistor layer. In a second surface region of the semiconductor substrate, a hetero junction bipolar transistor is constituted on the basis of only a second transistor layer separated form the first transistor layer. Since a plurality of heterojunction bipolar transistors are normally integrated for one pin-type photodiode, the thickness of the heterojunction bipolar transistors larger in number than the pin-type photodiode is set regardless of the thickness of the pin-type photodiode. the thickness of a high-resistance layer in the pin-type photodiode is set with an increased degree of freedom. When the first surface region of the semiconductor substrate is the inner region of a recessed step portion, and the second surface region of the semiconductor substrate is the outer region of the recessed step portion, a difference in thickness between the heterojunction bipolar transistor and the pin-type photodiode is absorbed by the depth of the recessed step portion. For this reason, the pin-type photodiode and the heterojunction bipolar transistor are formed to have almost the same surface level.

IPC: F01N13/04
Filed: 1995-03-21
Abstract: Filter has a filter main body, a container, a first counter room, and a second counter room.          A counter air is introduced into the first counter room through the counter air discharge valve, and fine particles trapped in the filter main body are removed and transported to the second counter room.  Then, the removed fine particles are further transported to a process portion isolated from an exhaust gas passage, and the fine particles are fired in the process portion.          Since the process portion is isolated from the exhaust gas passage, the fine particles in the process portion is not returned to the filter main body.  Moreover, since the fine particles are transported by the counter air only to the second counter room, it is possible to reduce an amount of the counter air.

Filed: 1996-04-10
Abstract: Three elements are hydraulically coupled by a hydraulic fluid contained within one of the elements serving as a housing so that reciprocally driven motion of one of the elements is transmitted to move another element responsively in a reciprocal motion.  The movements can be counter-reciprocal or co-reciprocal, and the housing can be an unmoved element or can be one of the reciprocally moving elements.  The stroke lengths and velocities of the reciprocal movements can vary, and the effect can involve dynamic balance, power transformation, vibrational dampening, and many variations of these possibilities.
Patent CA-2174200-A1 (CA)
Inventor: RICHARDSON HUBERT JR
IPC: F16K15/06
Filed: 1996-04-15
Abstract: A scroll compressor is provided with a check valve which is disposed in a suction chamber adjacent a suction port opening.  The check valve provides fast response and enhanced operating characteristics for preventing reverse refrigerant flow and reverse scroll operation during compressor shutdown.  During normal compressor operation the check valve is open to allow communication of refrigerant into the suction chamber where the refrigerant is acted upon by the scroll mechanism and discharged through a discharge port.  A positive pressure differential exists between the discharge port and the suction port which unimpeded causes reverse scroll operation upon compressor shutdown.  The positive pressure condition in the suction chamber forces the check valve to pivot to a closed position whereby it covers and substantially seals the suction port.  By preventing reverse refrigerant flow through the suction port the check valve effectively eliminates the pressure differential and thereby prevents reverse scroll operation.
