Filed: 1988-03-09
Abstract: PURPOSE:To enable a silicon wafer which is of high precision and has little curvature, to be separated by cutting and at the same time, lengthen the life of a cutting edge, by jetting in pressurization the grinding liquid of alkalinity at least toward the starting point of cutting in. CONSTITUTION:When a silicon single crystallization stick 1 is processed in milling by using an inner perimeter type cutting edge 2, the liquid of grinding is jetted in pressurization from a nozzle 6 toward its cutting in starting point 4.

Title: Hot water stable feed device in boiler
Inventor: SUGANO YOSHIHIRO
IPC: F24D17/00
Filed: 1989-03-09
Abstract: PURPOSE:To always feed a specified quantity of hot water regardless of the number of use of a hot water feed plug by providing a pressure detection part at the discharge side of a hot water pump, a plurality of hot water feed plugs at the downstream side of the pressure detection part and a flow control means receiving a signal of the pressure detection part the downstream side of the hot water feed plugs for its operation. CONSTITUTION:A hot water feed pump 3 is operated to circulate hot water in a hot water circuit 2, where not water feed can be performed by opening hot water feed plugs 3. At this time, since a pressure detection part 4 detects a pressure which is higher than a set pressure, the signal is transmitted to a flow control means 6 such as a solenoid valve to enlarge a circulation flow. As the result, the pressure of the upstream side of the flow control means 6 lowers and a proper quantity of the hot water can be fed from opened hot water feed plug 5. In addition, for instance, in the case where the four hot water feed plugs 5 are opened wholly, the pressure detection part 4 attains a pressure lower than a set pressure to transmit the signal to the flow control means 6 so as to stop or limit the circulation of the hot water. As the result, a quantity of hot water feed from each hot water feed plug 5 increases.
