Title: Head return circuit with hold function
Inventor: RI KANJO
IPC: G11B21/12
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain a head return circuit which can return a head to a safety zone irrespective of the advance direction of the head by, when a head return signal is input, removing a voltage which is applied across both ends of a motor during a prescribed time, stopping the head is stopped, and then executing its return operation. SOLUTION: A lower-side drive part 400 outputs a driving voltage which is made variable by signals which are outputted from a switch part 100 and a reference-voltage generation part 200. When a comparator 330 judges that a second voltage V2 is smaller than a first voltage V1, an upper-part drive part 500 does not generate a driving voltage. Out of both ends of a voice coil motor, a driving voltage is input to one end side to which the output of the lower-side drive part 400 is connected, and no driving voltage is input to the other end side to which the output of the upper-side drive part 500 is connected. Consequently, a head which is moved to a direction which becomes near from a safety zone or to a direction which is far from the safety zone stops its operation during a set time, i.e., during the time in which the second voltage V2 is amller than the first voltage V1.

Title: Sequence controller
Inventor: SEKIYA YOSHIAKI
IPC: G05B19/05
Filed: 1989-06-05
Abstract: PURPOSE:To shorten the program processing time and to improve the memory efficiency by using a NOP code production circuit which produces forcibly an instruction code and gives it to an MPU to minimize the executing time. CONSTITUTION:A NOP code generating circuit 3 produces a NOP instruction and sends it to a data bus 16 to minimize the executing time when a microprocessor MPU 1 fetches an operation code for an area where a sequence program 4 decided previously to a main program 2 of the MPU 1 is carried out. As a result, a one-step sequence instruction can be carried out within a time when the NOP instruction requiring the minimum executing time is carried out. Thus the high speed performance is secured. Furthermore the memory capacity can be saved because it is not required to store the NOP instruction into the program 2.

Title: Semiconductor device
Inventor: SHIRATO TAKEHIDE
IPC: H01L29/78
Filed: 1989-06-05
Abstract: PURPOSE:To relieve the concentration of an electric field in a region under a gate electrode and suppress the generation of hot carriers and avoid the deterioration of a transmission conductance by a method wherein a one conductivity type channel doped region which is formed in the region under the gate electrode and has a higher impurity concentration than a semiconductor substrate is separated from a source region and a drain region by the same distance. CONSTITUTION:A gate electrode 7 is provided on a p-type silicon substrate 1 with a gate oxide film 6 between. A channel doped region 3 is formed in a region under the gate electrode 7 so as to be separated from both the ends of the longitudinal direction of the channel of the gate electrode 7 in a self-alignment manner. An n<+>-type source region 4a and an n<+>-type drain region 4b are formed in a self-alignment manner with the gate electrode 7. The channel doped region 3 are separated from the source region 4a and the drain region 4b by the same distance. As the high impurity concentration source and drain regions and the relatively high impurity concentration channel doped region can be separated from each other, the concentration of the electric field can be relieved and the generation of hot carriers can be suppressed, so that a hot carrier effect can be improved and the aging deterioration of a transmission conductance can be avoided.

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To improve workability by a method wherein a pair of flat plate- shaped parts for both sides provided respectively at both sides of a pair of webs of a hat-shaped pile are held respectively with a set of chucks. SOLUTION: Flat plate-shaped parts 12c1 , 12c2 for both sides provided at both sides of a pair of webs 12a1 , 12a2 of a hat-shaped pile 12B are held respectively with a set of chucks 13c, 13d. Since the dimension W1 of the holding width held with the chucks 13c, 13d becomes large, becoming almost 100% against the dimension W2 of the overall width of the pile 12B, holding becomes certain and apparent rigidity of the pile 12B is heightened. Then, fixed claws 13c1 , 13d1 and movable claws 13C2 , 13d2 of the chucks 13c, 13d are connected respectively with connecting plates 13e1 , 13e2 to heighten rigidity, and thereby the state of holding for the pile 12B is made certain furthermore. The chucks 13c, 13d are installed at one unit of pile-driving/pile-extracting machine.  Thereby, highly accurate adjustment becomes possible for tilting angle positions, and torsional deformation and the like liable to occur on an occasion of pile driving can be reduced.

Title: Semiconductor device
Inventor: SASAKI NOBUO
IPC: H01L27/12
Filed: 1977-11-29
Abstract: PURPOSE:To obtain SOS.MIS.FET which features a small amount of the leak current inspite of a large amount of the mutual conductance, by narrowing the channel width of the PN junction formed with the drain region and the channel region and also widening the channel width of other areas. CONSTITUTION:Source region S and drain region D are formed on the semiconductor substrate, and then channel region C is grown between region S and D. In this case, channel width W is narrowed near the PN junction, and width W' of region C is set to several times as large as W. As a result, the leak current flowing between the source and drain regions through the area around the island is decreased because of the long path. At the same time, the mutual conductance is increased greatly, thus increasing the current amplification factor. Accordingly, this method becomes very effective when the substrate featuring rather inferior crystalline property is used.
