摘要:
A semi-conductor wafer processing information system which includes a sensor responsive to the presence of a wafer at a monitored location of a processing machine to read the wafer identification scribe and send both wafer and machine identification signals to a host computer which may be independent of a wafer tracking system. The computer determines whether processing at the selected machine is appropriate. Wafer history information is updated when the wafer departs a given machine.

A base headboard for supporting the back of an injured person's head has an elongated slot with teeth racks disposed on either side of the injured person's head. The headboard also comprises straps for attaching to a spine board. Two side head blocks are removably attached to the headboard using plunger-type locks that engage an elongated slot on each side of a center portion of the headboard. Each lock is engaged to a slot of the headboard through a separate elongated slot in the corresponding head block. Advantageously, a head block may be adjusted by moving the engagement of the lock along each independent slot in the headboard and head block, respectively. In addition, a head block may be rotated around its lock.

An electronic brake controller operates in both an automatic and manual mode. In the automatic mode, the electronic brake controller applies a pre-specified percentage of braking for the brakes of a towed vehicle. In the manual mode, the electronic brake controller is capable of applying one-hundred percent of braking regardless of the setting for the pre-specified percentage of braking set for the automatic mode.

An electric drill (10) has a drive assembly (31, 70), and a pivot head (32) having first and second bit gripping assemblies (14, 22) disposed at 90 degrees to each other. The electric drill (10) also includes means for adjusting the position of the bit gripping assemblies (14, 22) relative to the drive assembly (31, 70) by pivoting the head (32) through 90 degrees, whereby a selected one of the bit gripping assemblies is operatively engaged to the drive assembly. The position adjusting means may include a movable locking sleeve (36) which, in a first position, allows the drive assembly to operatively engage the selected bit gripping assembly and, in a second position, allows the drive assembly to disengage the selected bit gripping assembly.
