Title: Excavator
Inventor: KOIDE KATSUO
IPC: E21B10/40
Filed: 1993-05-18
Abstract: PURPOSE:To improve durability by improving strength of a hole expanding bit, and excavating efficiently with low torque rotation. CONSTITUTION:A slidable cylinder body 20 is arranged between a device 7 and a hitting collar 2. A hitting ring 21 to be arranged between the step parts 17 and 18 is arranged on the base end of this cylinder body 20. A hole expanding bit 22 having a diameter larger than the hitting collar 2 is arranged on the tip projecting from the hitting collar 2 of the cylinder body 20. Thereby, since the whole excavation surface K is excavated by the hole expanding bit 22 and a bit head 11, rotational resistance of the bit head 11 and the hole expanding bit 22 is reduced, so that a device can be rotated with low torque. Thereby, abrasion of a rotation transmitting part such as a spline groove is reduced. Partial abrasion of the bit head 11 and the hole expanding bit 22 is also reduced, so that durability is improved.

Title: Manufacture of discoid information carrier which can be read optically
Inventor: DEIITAA BARUTOORUTOZEN
IPC: B29C45/56
Filed: 1981-07-28
Abstract: A method for manufacturing high information density storage disks, suitable for optical reading, out of transparent synthetics having a high glass temperature and high dimensional stability. The present injection molding method avoids potential double diffraction disruptive effects created by frictional or shearing forces. The synthetic material which is to be pressed is injected into one of the mold halves at a temperature that significantly exceeds the pressing temperature of the compression form and is injected so as to form a lump of the material. The pressing step wherein the compression form is closed down to a squeezing gap width is initiated prior to the termination of the injection operation. Likewise the cooling operation is initiated prior to the termination of the pressing step and both the cooling and pressing operations chronologically proceed at approximately an exponential rate.

Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from withdrawing from a gas station without paying an oil charge and prevent the charge from being adjusted with a charge of another meter by a method wherein a ticket issuing machine issues a numbered ticket when oil feed is finished and an alarm stops operation when payment is completed. SOLUTION: At a gas station 1, a numbered ticket is issued from a printer 5c of a ticket issuing machine 5 in response to an oil feed complete signal from a meter 4. A customer receives the numbered ticket 5d from the ticket issuing machine 5 and comes to an office, where when an operator inserts the numbered ticket 5d into a bar code reader 8a of a fare adjustment machine 8, an oil feed strip with oil feed data printed is issued from a printer 8d, and a payment complete signal is output from the fare adjustment machine 8 to an alarm 6. On the other hand, a rotating light 6c of the alarm 6 goes out with the payment complete signal received, and a gate 6d returns from a horizontal position to a hanging position, to allow the customer to withdraw from the gas station 1.  Thus since the alarm 6 continues to operate until payment is complete, withdrawal of a vehicle without payment of an oil charge can be prevented.
