Title: Exhaust silencer for general purpose engine
Inventor: ASAI KATSUTOSHI
IPC: F01N1/08
Filed: 1992-04-20
Abstract: PURPOSE:To purify exhaust gas and to reduce flow noise by making the inside of the tail pipe of an exhaust silencer for a general purpose engine into a honeycomb structure body provided with a lot of fine passages and carrying an exhaust gas purifying catalyst in the structure body. CONSTITUTION:A partition plate 5 divides the inside of an exhaust silencer main body 1 into the first expansion chamber 3 and the second expansion chamber 4. Small holes 6 are opened in the partition plate 5. Small holes of an inlet pipe 7 are opened into the first expansion chamber 3. A tail pipe 8 is formed into a honeycomb structure with its inlet side opened into the inside of the second expansion chamber 4 and its outlet side opened into the atmospheric air side. A catalyst 10 is carried on the inner walls of fine passages inside of the tale pipe 8. Exhaust gas emitted from a general purpose engine flows from the inlet pipe 7 into the first expansion chamber 3, then into the second expansion chamber 4, and passes the catalyst 10 while making control with it. The catalyst 10 is equipped with the purifying action and streamlining action at the same time against exhaust gas. In this way, flow noise is reduced and pollution-free gas is emitted into the atmospheric air.

Title: High-speed searching system for reproducer of disk-shaped information recording medium
Inventor: ABE RYOZO
IPC: G11B27/10
Filed: 1980-09-12
Abstract: PURPOSE: To ensure a high-accuracy search in a short time, by detecting the duration of a reproduced address signal when a desired program number is detected while shifting a reproducing stylus in a high speed, then shifting the stylus by an extent equivalent to a track pitch after shifting the stylus backward in a speed corresponding to the interval between the position of the reproducing stylus and the initial position of the program.  
     CONSTITUTION: When a desired program number is detected by a detector 6 during a high-speed shift of a reproducing stylus 3, a deciding device 7 detects whether the upper 4 bits of a locak address are all 0 or not. If these bits are not all 0, the stylus 3 is shifted backward while the speed is gradually reduced in accordance with the interval between the position of the stylus 3 and the initial position of the program. When the upper 8 bits of the local address are all set at 0, the stylus 3 is shifted via a kick pulse generator 8 and by an extent equivalent to a track pitch. Then a feeding device 4 is set at a speed of the normal reproduction mode to actuate a tracking servo circuit. In such way, a high-accuracy search is executed in a short time.
