Title: Grain drying control system for grain dryer
Inventor: NISHINO EIJI
IPC: F26B25/22
Filed: 1991-01-31
Abstract: PURPOSE:To enhance cooling efficiency by changing a cooling method according to the state of open air when cooling dried grains is effected in a cooling device. CONSTITUTION:The moisture and temperature of dried grains are detected with a moisture sensor 23 and a grain temperature 52 while the temperature and humidity of the open air are detected with an open air temperature sensor 53 and an open air humidity sensor 54. The equilibrium moisture content of the open air is computed with a CPU 59 of a drying control device 61 based on the temperature and the humidity. The differential temperature between the detected dried grain temperature and the open air temperature is compared with a preset differential temperature. When the computed differential temperature exceeds the preset differential temperature, and the equilibrium moisture content is higher than the moisture of the detected dried grain temperature, the dried grains are circulated in the cooling device and cooled therein. When the equilibrium moisture content is lower, the dried grains are cooled by ventilating and circulating in the cooling device. The cooling method for the dried grains is changed based on the open air condition, which protects the dried grains from absorbing the moisture and hence enhancing the cooling efficiency dramatically.

Title: Processing method for sealing surface of casting and grindstone used therefor
Inventor: SASAMORI TAKEFUSA
IPC: B24B15/00
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To correct a casting defect of a casting used under high temperature by grinding a sealing surface of the casting in a state of holding flat surfaces formed on head ends of abrasive grains roughly in parallel with the sealing surface of the casting. SOLUTION: A sealing surface of a cylinder block is ground and processed in more than about 0.1mm of cutting quantity by horizontally moving a grinding grindstone 1 while rotating it by a grinder. Consequently, the sealing surface of the cylinder block is ground by flat surfaces 17f and inclined surfaces 17t of diamond abrasive grains 17. As grinding is carried out by scrubbing the sealing surface of the cylinder block by the flat surfaces 17f of the diamond abrasive grains 17, grinding resistance becomes large and a plastic flowing layer is formed on the sealing surface of the cylinder block. Consequently, casting blowholes within specified depth from the sealing surface are efficiently crushed.

Title: Reflection type ultrasonic detector
Inventor: OKAMOTO MINEO
IPC: G01S15/10
Filed: 1979-01-31
Abstract: PURPOSE:To eliminate malfunction due to interference from the adjacent ultrasonic switch by controlling the second ultrasonic switch transmitter by close-signal of gate circuit that restricts the first ultrasonic switch detection area, in case both ultrasnoic switches are located in the same sound field of reflection type US. CONSTITUTION:There are transmitter 1 that emits ultrasonic wave pulse by application of output from oscillator 2, and receiver 4 that receives reflected wave of emitted ultrasonic wave from the object to be detected 13. Output from the receiver 4 is supplied to detector D via gate circuit 6 that opens for a given period of time t2 after ultrasonic wave is emitted. The gate circuit 6 of the adjacent ultrasonic switch A in the same sound field emits close-signal, which, detected by differentiator 7, triggers univibrator 3 that controls the transmitter 1 of ultrasonic switch B. This causes ultrasonic switch B to be operated after completion of detecting operation of ultrasonic switch A. Therefore, if two or more ultrasonic switches are adjacently located, one ultrasonic switch receives reflected ultrasonic wave from another ultrasonic switch, so that no malfunction occurs.
