Title: Agar having reduced dissolving temperature
Inventor: NAKAZONO DAISEI
IPC: A23L29/20
Filed: 1982-05-07
Abstract: PURPOSE:To obtain industrially and advantageously agar having reduced dissolving temperature in water, by heating the agar at a specific temperature by the wet heating method. CONSTITUTION:An aqueous solution of agar or a mixed slurry of the agar with water is heated to 100 deg.C or above. The ratio of the agar to the water to be used is optional, but in many cases, 10pts.wt. agar may be used with 200-0.2pts.wt. water, and particularly 0.1-1pt.wt. water is industrially advantageous. The heating temprature is 100 deg.C or above and an optional temperature up to the starting of the coloring and carbonizing of the gelatinous material of the agar. The higher the temperature within the above-mentioned temperature range, the shorter the heating time. For example, 3-4min heating time is sufficient in an opened system at 100 deg.C, and 2-3sec heating time is sufficient in the opened system at 270 deg.C.

Title: Blower
Inventor: SHIN MASAHIRO
IPC: F04D29/54
Filed: 1987-03-31
Abstract: PURPOSE:To substantially improve static pressure efficiency and the noise characteristic, by successively mounting a cone-shaped guide and a blown air circuit member in the downstream side of an impeller further setting the minimum diameter of the blown air circuit member to a proportion of specific range for the outside diameter of the impeller. CONSTITUTION:A mixed flow fan provides in the downstream side of its impeller 1 a cone-shaped guide 4 which approaches the impeller 1 being vertically arranged to its rotary axis while spreads a diameter gradually from a size almost equal to the diameter of the downstream side end surface in a hub part of the impeller 1. And the fan mounts the first blown air circuit member 5 to an end surface in the downstream side of the guide 4 to be vertically set to the rotary axis of the impeller 1. While the fan, setting the second blown air circuit member 6 almost parallelly, opposed to the first blown air circuit member 5, forms a blown air circuit. Here the fan sets a minimum diameter D2 of the first blown air circuit member 5 to within a range of 0.85D1-1.2D1 with respect to the outside diameter D1 of the impeller 1. In this way, the fan, converting most of the speed energy into a static pressure, improves static pressure efficiency and the noise characteristic.

Title: Fuel injection controlling method
Inventor: NOROTA KAZUHIKO
IPC: F02D41/10
Filed: 1983-05-04
Abstract: PURPOSE:To obtain an excellent accelerating performance of an engine over the entire range of engine speed, by increasing the quantity of fuel supplied in inverse proportion to the asynchronous injection with decreasing of the engine speed in a particular range of the engine speed. CONSTITUTION:In controlling fuel injection by an electronic control circuit 22, the quantity of fuel supplied in inverse proportion to the asynchronous injection is increased with decreasing of the engine speed in a particular range of the engine speed. That is, when a throttle valve is opened from its completely closed position, the state of acceleration is detected at first. If it is detected that the engine is in acceleration, the period of asynchronous injection is determined at the next step. The period of asynchronous injection is determined according to the engine speed NE. For instance, when the engine speed NE is higher than 2,000rpm, the period of asynchronous injection is kept constant at 2ms. On the other hand, when the engine speed is lower than 2,000rpm, it is increased with decreasing of the engine speed. Further, when the engine speed NE is lower than 1,000rpm, the period of asynchronous injection is kept constant. By thus effecting asynchronous injection on the basis of the above period, it is enabled to obtain an excellent accelerating performance of an engine over the entire range of engine speed.
