Abstract: PURPOSE:To miniaturize and simplify a circuit and to display a high speed characteristic which light has to a maximum by providing two optical half adders where an optical signal executes input/output, and an optical latch memory. CONSTITUTION:The adder consists of two optical half adders 1 where the optical signal executes input/output, and one optical latch memory 2 which executes delay for one clock. When two binary numbers A and B are sequentially inputted to the optical half adder of a former stage by making up digits, the sum outputs are given to one input of the optical half adder in a post-stage for respective digits, and a carry output C is given to the optical latch memory 2. Data which is temporarily stored in the optical latch memory 2 is added to the sum output of the subsequent digit by the optical half adder 1 in the former-stage by the optical half adder in the post- stage. Consequently, the sum of the binary numbers is obtained as the sum output S of the optical half adder 1 of the post-stage. Then, an operation result can be outputted for one clock by constituting the optical half adders 1 and 1 in such a way that the optical signal executes input/output, and the operation speed of the full addition operation is prevented from being damaged even if they are connected in serial. Thus, the operation speed is improved.

Filed: 1978-12-29
Abstract: PURPOSE: To suppress an occurrence of unburned fuel through allowing a gas layer to exist on a wall unitl combustion stroke is over and also eliminating a quenched layer by introducing a gas different largely in specific gravity from a sucked mixed gas onto the wall of a combustion chamber.  
     CONSTITUTION: A quenched layer filling gas passage 8 is provided on a suction port 1. The passage 8 is constituted so that a gas will form a swirl along inside wall 2' of a combustion chamber 2 when a suction valve 4 opens, thereby forming a gas layer 9 around the wall of the combustion chamber 2. Gases which are small in specific gravity as compared with the mixed gas like H 2 , He, Ne, etc. or which are larger in specific gravity than the mixed gas like CO 2 , Ar are used for the quenched layer filling gas. From forming the gas layer 9 by means of these gases, a major part of the gas remains existing in the neighborhood of the wall even at compression stroke, therefore a quenched phenomenon of flame at the wall can be prevented, and thus a formation of unburned HC can be decreased.
