Title: Manufacture of semiconductor device
Inventor: KUSAKAWA HIROTSUGU
IPC: H01L29/80
Filed: 1986-07-08
Abstract: PURPOSE:To control a threshold voltage easily and accurately by forming a channel area having an impurity concentration lower than that of source/drain layers on a substrate surface where the source/drain layers are removed after forming the source/drain layers having high impurity concentration at FET areas of the semiconductor substrate surface. CONSTITUTION:A high-concentration source/drain areas 16 (n<+> type semiconductor layers of low resistance) having a designated thickness is formed on the surface of semi-insulating substrate 11 and the n<+> type semiconductor layers 16 is removed by etching in the area for a channel region so as to form a recessed portion 17. Furthermore, prescribed impurity ions are implanted in all the FET areas to form a channel region 15 having a designated thickness at a lower portion of the recess portion 17. The channel area 15 (n<+> type semiconductor layer) is lower in concentration than the remaining source and drain areas 16. Thus, the threshold voltage value can be controlled easily and accurately.

Title: Press device for ic lead frame
Inventor: KENMOCHI YOSHIJI
IPC: B29C45/14
Filed: 1986-07-08
Abstract: PURPOSE:To reduce the quantity of the stroke of molds between a top force and a bottom force by making the quantity of the stroke of molds between the top force and the bottom force slightly larger than the size of the thickness of a holder and projecting and retreating the holder under a horizontal state. CONSTITUTION:An IC lead frame 33 is set onto the push surface 46 of a bottom force 21 by a feed chain 34 under the state in which it is held by a holder 32. Consequently, since the work space of an operator need not be considered, a distance between a top force 20 and the bottom force 21, the quantity of the stroke l of the top force 20 as the movable side in this case, need not be set at a large value. That is, the stroke l is formed in an extent that it is made slightly larger than the size of the thickness of the holder 32, and shaped in a degree sufficient for projecting and retreating the holder 32 under a horizontal state. Accordingly, the no-load travel of the top force 20 is shortened, hydraulic oil used may also be reduced only by the shortening section, and a valve, etc. controlling oil may also be decreased.

Title: File update retrieving processor
Inventor: CHIBA MEGUMI
IPC: G06F12/08
Filed: 1989-06-21
Abstract: PURPOSE:To reduce the read generation rate of a user program from a file and to improve the efficiency of processing by allowing a user data block prereading means to preread a user data block asynchronously with a user program. CONSTITUTION:The user program 10 reads out the user data block 50 from the file 5 through a buffer control means 3 in case of updating/retrieving the file 5, and at the time of deciding the generation of prereading in the read block 50, accesses a prereading signal sending means 2 to send a prereading signal to the user data block prereading means 4. The means 4 decides the block 50 to be preread based upon the contents of the block and that of a control data block 51 and reads out one or more blocks to the buffer 30 by using a prereading means in the means 3. When the user program 10 requests the reading of the buffer 50 to the means 3, the block 50 is efficiently read out without reading out the block 50 from the file to the buffer 30. Writing processing is similar to conventional processing.

Filed: 1990-06-20
Abstract: PURPOSE:To output pieces of information on a speed and a direction at the same time without increasing the number of outputs by varying the pulse width of output pulses of the speed detector and multiplexing the direction information with the speed information. CONSTITUTION:When a disk 1 rotates forward at a constant speed, slits of the disk 1 crosses a photointerrupter 4, which sends its output signal 2 to a microcomputer 5. The current waveform of the signal 2 is an output signal waveform 6 in the constant-speed forward rotation, the pulse width of a high- level signal corresponding to slit width varies in the order of W1, W2, W3, W4, W1, W2..., and the pulse width ratio is 1:2:3:4. Further, when the disk 1 reverses at the constant speed, the signal 2 has an output waveform 7 in constant-speed reversing and the width of the pulse signal varies in the reverse order of the forward rotation. For the purpose, the order of variation in the width of the signal pulses is analyzed to decide the rotating direction. When the rotating speed is detected, a microcomputer 5 measures the period T of the edge of the signal 2 corresponding to the rotating direction to detect the speed of the disk 1.

Abstract: PURPOSE:To support the centrifugal forces applied to balance weights by a metallic tube which is put on the outer peripheral sections of magnets so as to reduce the burdens of clamping pins by extending the metallic tube to a position where the tube can cover the outer peripheral sections of the balance weights and bringing the outer peripheral sections of the balance weights into contact with the extended part of the metallic tube. CONSTITUTION:A metallic tube 3a is provided with an extended part 5 formed by extending the tube 3s in the axial direction so as to cover the outer peripheral parts of balance weights 12a and the outer peripheral parts of the weights 12a are brought into contact with the internal surface of the section 5. As a result, the burdens of clamping pins 9 can be reduced, since the centrifugal forces applied to the weights 2a are supported by the tube 3a. Accordingly, backlashes hardly occur between the weights 12a and an end plate 4 even when the pins 9 have caulking defects, etc., and the occurrence of vibrations and noise can be prevented. In addition, scattering of the weights 12a is also prevented. Therefore, a rotor which can exhibit an excellent capability at the time of high-speed rotation can be obtained.
