Title: Injection mold
Inventor: NAKAJO HIROSHI
IPC: B29C45/26
Filed: 1992-06-18
Abstract: PURPOSE:To prevent stringing and a variation in cutting position when a resin is cut at a gate by a method wherein a tip end part of a pin is inserted to the gate from the opposite side of a product surface provided with the gate, and the tip end of the pin is made acute to form a minimum cross sectional area part on a cutting position. CONSTITUTION:A gate 1 is provided on a product surface F of an injection mold 5. A pin 2 is disposed in the gate 1 from the opposite side of the product surface F. The pin 2 comes close to the product surface F to be inserted to the gate 1. The tip end of the pin 2 is made acute. A minimum cross sectional area part S is formed on the side opposite to the gate. Thus, a resin can be cut on the product side. In cutting, the resin is acceleratedly set at the minimum cross sectional area part S, thus being prevented from stringing in a melting state. Furthermore, a variation in cutting position is also prevented. In this manner, there is no possibility that the resin may remain in the gate under the product surface. Therefore, the need for forming a draft in the gate of the mold is eliminated, and the metallic mold can be easily machined.

IPC: B41J23/32
Filed: 1987-06-26
Abstract: PURPOSE:To use an energy generated in a coil as an energy to reduce the power demand of a wire dot printer by a method wherein the energy generated in the coil is accumulated into a condenser, an electric current is inhibited from flowing a power source to the condenser, and the energy is converted to an AC by switching to be returned to the power source through a rectifying means. CONSTITUTION:A control circuit 5 issues a signal keeping ON a lead-in means 7 only for a predetermined period of time, to the lead-in means 7 when stopping a drive signal. The lead-in means 7 is turned ON according to this signal and leads an energy generated in a coil 3 to a condenser 8. At this time, a breaking means 6 interrupts an electric current flowing from an power source E to the condenser 8. The control circuit 5 issues an ON/OFF switching signal with a high frequency to a switching means 9 when stopping the signal which have been sent to the lead-in means 7 for the predetermined time. The switching means 9 fetches the energy accumulated in the condenser 8 and intermits it by the switching signal. A trans 10 foosts the inputted high-frequency AC, and a rectifying means 11 rectifies the AC to issue it to the power source E.

Abstract: PURPOSE:To measure an accurate flow rate without being affected by various conditions by fitting a flow straightening net on the upstream side of a nozzle and forming the flow velocity distribution of liquid to be measured which enters the nozzle. CONSTITUTION:The flow straightening net is fitted in the flow passage of the fluid to be measured on the upstream side of the nozzle 3.
