Title: Insulation gate field effect transistor and its manufacture
Inventor: ONO KEIICHI
IPC: H01L29/78
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To form a source/drain impurity region having structure that so deep that salicide technology is applicable and thinner layer is attainable in practice with no use of selective epitaxial growth, and to raise the impurity concentration only just below a channel for suppressed short channel effect. SOLUTION: The surface of a semiconductor substrate 1 (or a semiconductor layer supported by a substrate) is etched to form a groove 1a. In a semiconductor region contacting to the inner bottom surface of the groove 1a, a channel impurity region 5 with a concentration higher than the surroundings (impurity regions 6a and 6b) is formed. A gate electrode 3 is formed in the groove 1a while, at least, a part of it is embedded via a gate insulating film 2. An impurity is added to a semiconductor region around the groove 1a, and source/drain impurity regions 4a and 4b are formed deeper than the inner bottom surface of the groove 1a.

Title: Guide type motor car
Inventor: MORISHITA YOSHIICHI
IPC: G05D1/02
Filed: 1985-01-19
Abstract: PURPOSE:To simplify a resetting job of a motor car by setting the car automatically onto a guide line if the car is stopped by detachment of a caster at a position near a place where an alternating magnetic field is detected from the guide line. CONSTITUTION:A cart main body 1 running on a guide line 17 moves to a position B from a position A and the distance between a pickup coil 18 and the line 17 is set at L. If this distance L is smaller than an allowance distance X, the main body 1 is driven continuously with guide since the amplified detection voltage (e) given from the coil 18 is larger than the 1st reference voltage E1. When the distance L is larger than the distance X and smaller than a distance Y, E2<=e<=E1 (E2: the 2nd reference voltage) is satisfied. Thus the drive of the body 1 is stopped. In such a case, an operator releases the stop state after confirmation of safety and resets automatically the body 1 onto the line 17. If the distance L is larger than the distance Y, e<E2 is satisfied and the drive of the body 1 is stopped. Then the operation is switched to motor drive mode or a manual drive mode to set the body 1 again on the line 17.

Title: Digital radio equipment with interception prevention
Inventor: TAMURA MASAKATSU
IPC: H04B1/40
Filed: 1989-01-18
Abstract: PURPOSE:To prevent interception by the 3rd party in the event of stealing by erasing a data (CH data or privacy call code data) stored in a RAM after backup for a prescribed time when a battery pack is removed from a radio equipment main body so as to lose the function of the radio equipment. CONSTITUTION:In order to back up a data stored in a RAM such as a CH data or a privacy code data for a required minimum time, a short-time backup element 4 to store a required electric charge is employed thereby losing the backup capacity after a prescribed time (such as 10-20sec), erasing the stored data and destroying the function of the radio communication equipment. Since a 3rd party does not know the design, the battery pack 2 is removed carelessly, but the user in this system quickly replaces the battery as required. Thus, the function maintenance of the radio equipment is attained and the interception is prevented.
