IPC: F25C1/14
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the icerqaking water mixed with relatively large quantity of the air from flowing into a refrigerating casing. SOLUTION: One end of a supply tube 49 is connected to the supply port 47 of a refrigerating casing 11, and the other end is connected to the outlet 53 of an icemaking water tank 51. A channel valve 55 is provided at a supply tube 49, and a drain tube 59 branched from the supply tube is provided at the upstream of the valve 55. A drain valve 57 is provided at the tube 59.

Title: Intake-air controlling apparatus for internal-combustion engine
Inventor: SATOU HIROMI
IPC: F02M35/024
Filed: 1983-01-31
Abstract: PURPOSE:To improve the performance of an engine at the time of low-speed operation of the same, by preventing the air-fuel ratio from becoming too lean by providing an opening control valve at the inlet of an air cleaner of an internal-combustion engine having a carburetor, and decreasing the opening of the valve when the engine speed is low. CONSTITUTION:An opening control valve 6 is porivded at the inlet 5 of an air cleaner 4 disposed on the upstream side of a carburetor of an internal combustion engine, and the valve 6 is opened and closed by a rod 7 connected to a pressure-responsive chamber 8 that is communicated with an exhaust pipe. When the engine speed is raised, the opening of the valve 6 is increased by the rise of exhaust pressure and the flow rate of intake air is increased, so that the air-fuel ratio becomes high. When the engine speed is lowered, on the other hand, the opening of the valve 6 is decreased and the flow rate of intake air is decreased through increasing of resistance to the air flow, so that the air-fuel ratio is lowered. Since, with such an arrangement, the air-fuel ratio can be made closer to an optimum value at each speed of rotation of the engine, it is enabled to prevent the air-fuel ratio from becoming too lean, in particular, at the time of low-speed operation of the engine and to prevent unstable operation of the engine at the time of acceleration.

Title: Radio communication control equipment
Inventor: MURATA ICHIRO
IPC: H04L1/08
Filed: 1994-02-09
Abstract: PURPOSE:To improve connection probability and to shorten useless retransmisison time when the connection is disabled by setting the maximum number of retry corresponding to the connection probability in the case of retry absence to be fluctuated by environmental factors. CONSTITUTION:When the connection probability of no retry is p1, generally, the connection probability in the case of a retry number (n) is expressed by p(n)=1-(1-p1)<(n-1>. Namely, when the number (n) of retry is infinitely increased, the connection probability can be made close to 100%. However, even when the retransmission due to the retry is repeated, at a real system, probability of no established link channel exists. Therefore, by controlling the maximum retry number, the best connection probability for this system can be provided in a short time by retry. Namely, a retransmission contorller 16 measures the connection probability at a logical control channel depending on an environment by trying exchange between a base unit 1 and a hand set 2 some times and based on those data, the suitable maximum retry number can be set. Thus, the connection probability can be improved and the useless retransmission time can be shortened.
