Title: Nonvolatile semiconductor memory
Inventor: HAYASHIGOE MASANORI
IPC: H01L29/792
Filed: 1990-07-23
Abstract: PURPOSE:To perform high-speed readout by controlling the storage contents of a selection memory transistor to turn a selection bit line to be higher at the time of '1' and to turn a non-selection bit line to be higher at the time of '0'. CONSTITUTION:When '1' is stored in a memory transistor M1, the memory transistor M1 maintains an off state. So, potential V1 of a sense line SNL1 maintains Vcc to turned to be V1>V2. On the other hand, when '0' is stored in the memory transistor M1, the memory transistor M1 is turned on. So, a bit line BL1 is introduced through a selection transistor Q1 and a memory transistor M1 to a grounded level to turned to be V1<V2. Thus, high-speed readout can be performed.

Filed: 1984-09-20
Abstract: PURPOSE:To apply alignment of a bearing and gap adjustment of a rotary transformer at the same time by forming an upper ball bearing to be slid freely to a main shaft and a lower fixed cylinder at the gap adjustment of the rotary transformer. CONSTITUTION:A rotary support 6 is fixed to the main shaft 1 at assembling, the support 6 is adjusted for the position vertically so as to form a prescribed value for the gap of rotary transformers 8a, 8b and fixed by a screw 21. In this case, the upper part of the lower fixed cylinder 2 is expanded thermally and since the diameter of inner race of the upper ball bearing 3a is selected larger than the diameter of the main shaft 1 by 1mum, the ball bearing 3a is slid freely to the fixed cylinder 2 and the main shaft 1. The ball bearing 3a is slid downward by the support 6 against energizing of a coil spring 20 and then aligned and its outer race is pressed to the cylinder 2. Thus, the alignment of the bearing to give a pre-load to the bearing and the gap adjustment of the rotary transformers are attained by one process.

Abstract: PURPOSE: To utilize a stator current of a machine and thereby to conduct precise regulation of a magnetic flux by maintaining a direct-axis magnetic flux at a value corresponding to a fixed magnetic pole angle and a magnetic flux set value by compensating a set value of a direct-axis stator current. CONSTITUTION: In a magnetic flux model 8, a direct magnetic flux, a lateral magnetic flux and a magnetic pole angle of a machine are computed on the basis of currents id and iq and a measured value if of an excitation current. Herein the computed magnetic pole angle is equal to the magnetic pole angle in the case when it has an absolute value being smaller than a limit value which can be regulated independently, while a limited magnetic flux angle being equal to the limit value δ max is formed in the case when the computed magnetic pole angle has an absolute value being equal to or larger than the limit value δ max.  In order to maintain a direct-axis magnetic flux at a value- corresponding to the limited magnetic pole angle and a magnetic flux set value ψ, a set value of the excitation current is computed on the basis of the limited magnetic pole angle, the magnetic flux set value ψ and a set value of a direct- axis stator current and the set value of the excitation current compensates the set value of the direct-axis stator current.

Title: Gear profile cutting method
Inventor: NISHIMOTO MOTOO
IPC: B23F23/00
Filed: 1983-10-25
Abstract: PURPOSE:To prevent cutter relieving interference, lengthen the cutter life, enhance machining accuracy, and shorten the cutting cycle time by controlling the circumferential feed rate and radial feed rate in gear profile cutting work so that both can vary without breaking the predetermined relationship. CONSTITUTION:In gear profile cutting work, radial feed rate FRAD and circumferential feed rate (FROT)<n> can be varied, provided that relation FRADX(FROT)<n>=Q holds, where Q is a constant and 0<n<=1. With FRADO and FRATO entered from an operation board 4, a Q-value computing unit 3a figures out a Q value and gives it to a feeding rate operation unit 3b. On the other hand, an operation unit 3b divides a total depth of cut H, which is entered from the operation board 4, into the predetermined number of ranges, for example 3. The operation unit 3b sets the actual radial feed rate at K1.FRAD(K1>1) for the first cutting range in order to obtain high radial feed rate, while at K2.FRADO (1<K2<K1) for the intermediate cutting range, and the operation unit 3b instructs a servomotor 5 to follow the above setting. Thus, a cutting load can be uniform at the level close to the maximum allowable load for the total cutting stroke, thereby shortening the cycle time.

Title: Flame retardant tire and its manufacture
Inventor: HASHIMOTO TAKATSUGU
IPC: B60C11/00
Filed: 1992-07-03
Abstract: PURPOSE:To impart a tire effective flame-resistance and a fire preventive function without impairing any performance of the tire by forming a flame retardant layer, whose oxygen index is 25.0 to 50.0 and whose thickness is 0.005 to 0.3mm, on the outer surface of the tire whose oxygen index at the tread part is 19.8 to 27.5. CONSTITUTION:A flame retardant layer, whose oxygen index is 25.0 to 50.0, is formed on the outside surface, i.e., on the outer skin of the tire including a tread and a side. In this case, preferably, the oxygen index of the flame retardant layer is 28.0 to 45.0, further preferably 30.0 to 40.0. If the oxygen index of the flame retardant layer is less than 25.0, the tire will lack the flame resistance. On the contrary, if it is over 50.0, the tire will lack durability because of an occurrence of cracks. The thickness of the flame retardant layer formed on the outer surface of the tire is 0.3mm or less, preferably 0.005 to 0.25mm. If the thickness exceeds 3mm, the problem of cracks becomes acute, while, if it is less than 0.005mm, the tire will fail in showing effective flame resistance.
