Title: Wire aligning-winding method
Inventor: SATO DAISUKE
IPC: B65H54/28
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To completely prevent winding disorder such as the fall, dislocation or alignment collapse of a wire due to a wedge effect by making the feed pitch of the wire at collar side parts of a bobbin different from that at the center part of the bobbin to align and wind the wire. SOLUTION: At a bobbin collar side part, the feed pitch P of a wire is made equal to the outer diameter of the wire to suppress the fall and dislocation of the wire. At a bobbin center part, there is no anxiety about the fall and dislocation of the wire, so that the feed pitch P of the wire is made (d+g). When the wire turns of the collar side part is made (x), the distance W1 of the collar side part of a collar part 2 on one and side in a first layer is (X+1/2)d, and the distance W2 of the collar side part of a collar part 3 on the other end side is (xd). When the wire turns of the bobbin center part is made (y) (an optional integer) and a gap is made (g), the distance W3 of the center part is y(d+g), so that the collar-to-collar distance of a bobbin is W=(2 x+1/2)d+y(d+g).

Title: Resource control system for electronic computer system
Inventor: HIROHASHI AKIRA
IPC: G06F9/46
Filed: 1988-10-17
Abstract: PURPOSE:To eliminate the difference in mean resource wait time among respective groups by determining whether the assignment of resources is advanced or delayed according to the difference between the reference value of the mean resource wait time of each group and an actual mean resource wait time, and adjusting the quantity of reserved resources. CONSTITUTION:A group resource adjustment part 14 checks a job resource control table 122 at constant intervals of time and calculates mean values by the groups by subtracting the resource wait start time of jobs in a resource queue in the job resource control table 122 from the current time. Then the group resource adjusting part 14 obtains the reference value of the mean resource wait time of each group from a reference value control part 16. Then a reference value control part 16 requests a group resource control part 11 to increase the reservation quantity of a resources in a group (i) by a constant value (D) and decrease the reservation quantity of the resources in a group (j) by D. Consequently, the mean resource wait time of each group becomes equal.

Title: Floppy disk device
Inventor: YOSHIDA YUJI
IPC: G11B19/00
Filed: 1985-11-22
Abstract: PURPOSE:To abolish a start switch for adjustment, to simplify operations and to prevent malfunction by giving a specific identification function to a medium recording information necessary for adjustment and detecting said information so as to start an adjustment program. CONSTITUTION:A floppy disk 1 stores information necessary for adjustment and has two index holes 3-1 and 3-2 as the specific identification function. When the disk 1 is loaded on a device, an index detector 7 detects two holes 3-1 and 3-2, and a microcomputer 9 recognizes that they are specific disks. Then the device starts its adjusting action. Thus a switch changing over the action to an adjusting action is made unnecessary. Accordingly the operation can be simplified, and simultaneously erroneous writing to an adjusting medium due to malfunction can be prevented.

Title: Manufacture of semiconductor device
Inventor: SAKAMOTO YASUHIRO
IPC: H01L29/78
Filed: 1985-11-21
Abstract: PURPOSE:To make a crystalline grain boundary hardly generated in an active region while improving the characteristics as a thin film transistor as well as the manufacturing efficiency by a method wherein an amorphous region is solid-grown by heat-treatment further to form an active region in the solid- grown region. CONSTITUTION:A region 37 including an amorphous active region 24 is solid- grown by annealing process at 600 deg.C. At this time, the solid-growing process is performed in one (arrow a) direction from a source electrode 25 to a drain region 26 using the crystalline particles of polycrystalline silicon of residual part 24 as a core. Therefore, a crystalline grain boundary is not generated in the active region 24. Besides, the solid-growing time is shortened since said electrode 25 and region 26 are crystallized using the residual part 27 as a core before random nuclear production occurs. Resultantly, the movable degree mucan be improved while the leakage current can be reduced to improve the characteristics as a thin film transistor. Furthermore, the solid-growing time is markedly shortened to improve the manufacturing efficiency of thin film transistor.

Title: Liquid-phase epitaxy method
Inventor: YAMAMOTO KOSAKU
IPC: H01L21/368
Filed: 1985-11-20
Abstract: PURPOSE:To eliminate a variation in the composition of an epitaxial layer, by using a dummy wafer having such a characteristic that a variation in the composition of a saturated melt shifts along a solid-phase line of a phase chart and by determining the composition to be in a specific ratio when the epitaxy of a compound semiconductor is conducted. CONSTITUTION:When a melt having a composition indicated by a point O is used and CdTe is used as a dummy wafer, the composition of the melt varies in the direction of OA. When HgTe is used as the dummy wafer, said composition varies in the direction of OC. When a saturated melt is attained at a point A, in other words, a value (x) of an epitaxial layer at this point is 0.38, which deviates in a large degree from an initial target value 0.31. If a dummy wafer whose composition deviates in the direction of OB is used, therefore, the value (x) of the epitaxial layer remains 0.31 and no variation occurs, since the direction of variation is parallel substantially with a solid-phase line, in this case. By the application of a liquid-phase epitaxy method in this way, a process control of the epitaxy of a ternary or above compound semiconductor is facilitated, and thus the quality of crystal is improved.

IPC: F24F11/04
Filed: 1987-10-16
Abstract: PURPOSE:To obtain an air conditioning control device which incurs less device resistance loss by automatically modulating the set static pressure inside the duct by means of the lack or presence of the wide open signal of a VAV unit. CONSTITUTION:The VAV unit 7 automatically modulates the opening of its damper 10 so that it may maintain the set air volume with an actuator 9 regardless of the pressure fluctuations in the duct 6. If the temperature in a room 3 decreases, the pressure increase in the duct 6 is detected by a static pressure sensor 5 to reduce the static pressure setting RS1 with a pressure regulator 12, which causes a blower 2 to reduce its speed to control the air volume so that the temperature in the room 3 may be maintained at a constant level. At this time, the air conditioning device resistance curve R1 is also diminished to regulate the air volume to QA1 QB1 RC1 QD1.
