Title: Clean space coupling device
Inventor: HASHIMOTO NAOYUKI
IPC: F24F7/06
Filed: 1992-04-15
Abstract: PURPOSE:To ensure flexible coupling in clean spaces needed to fabricate semiconductors wherein prior art labor is eliminated and airtightness is surely kept with ease upon coupling the clean spaces.

Title: Facsimile equipment
Inventor: KOSHIRAE KOUSHIROU
IPC: H04N1/00
Filed: 1992-04-15
Abstract: PURPOSE:To decrease an undesired relay communication by making a relay transmission only when node number and sub node number corresponding to PB signal from a calling terminal are noncoincident with each other. CONSTITUTION:A communication control section 1 detects a second dial sent from a calling terminal at the time of an incoming call, reports the contents thereof to a document management controlling section 2. The control section 2 analyzes the contents, retrieving a node number storage section 3 to confirm whether the node number in the second dial is registered as a sub node number. If it is registered, the node number is replaced with a number stored in its own device node, and if not, the analysis result is stored in a document processing contents storage section 5 as the specified number as it is. The control section 2 accesses the storage section 5 at a fixed cycle, performing a relay transmission for only a signal showing that a specific node number corresponding to a PB signal is noncoincident with a sub node number. Thus, a coincident document is delivered from its own device, decreasing an undesired relay communication.

IPC: H02P27/06
Filed: 1995-04-20
Abstract: PURPOSE: To provide a motor controller for an electric car by which a maximum motor torque can be obtained while the uncomfortable torque vibration peculiar to a drive system is suppressed. CONSTITUTION: When the uncomfortable torque vibration peculiar to a drive system is generated and the amplitude of the torque vibration frequency component of the drive system of an induction motor is large and hence an output signal from a band-pass filter 33 is larger than a predetermined value, a field- reduction instruction calculation unit 25 reduces a field-reduction operation to increase the field intensity to suppress the uncomfortable torque vibration peculiar to the drive system. On the other hand, when the output signal from the band-pass filter 33 is smaller than the predetermined value, the field- reduction instruction calculation unit 25 increases the field-reduction operation to reduce the field intensity and increase the motor torque.  With this constitution, the motor torque is so controlled to be as large as the maximum limit at which the uncomfortable torque vibration is peculiar to the drive system is not generated.

IPC: H04Q3/58
Filed: 1983-05-31
Abstract: PURPOSE:To improve the service by switching automatically to the trunk alternative connection to have a direct-in-dial connection in case an extension calling subscriber has all busy private lines and therefore eliminating a waiting state for idle lines as well as the second operation of the dial. CONSTITUTION:A CPU6 connects an idle central office trunk 10 to a dial signal transmitter 9 via a channel network 5 for a direct-in-dial connection DID. Furthermore the CPU6 reads both private line and extension numbers out of a dial number storage device 7. The trunk line number corresponding to the private line number is previously stored in a private line/trunk line number storage device 8. Thus the CPU6 scans and reads the trunk line number corresponding to the private line number out of the device 8. Then the CPU6 transmits the number information obtained by combining the trunk line and private line numbers to a dial signal transmitter 9. The transmitter 9 produces a prescribed dial signal from said number information and transmits it to the trunk 10.

Abstract: PURPOSE:To contrive to prevent the vibration of a tilling apparatus, by constituting so as to rotate a rotation transmission case to whose top portions tilling claws... are supportedly attached... around the core of an intermediate shaft 17 attached to the lower portion of a fixed transmission case 14. CONSTITUTION:When an intermediate shaft 17 is rotated, a rotation transmission cases 16 and 16 integrally connected to the intermediate shaft 17 are rotated around the core of the intermediate shaft 17 and tilling shafts attached to the shaft ends of the rotation transmission cases 16 and 16 are rotated around the intermediate shaft 17 together with the cases 16 and 16. Since sprockets 26a, 26b and 26c have the same size and the same tooth number each other, the oblique angles of the tilling claws to the earth surface do not change and the tilling claws are always thrust into the earth surface in a constant oblique angle. The cases 16 wholly have a large moment of inertia on the above-mentioned rotation. When the tilling claws 32 and 32 of the extending member 16a on one side are rotated downward to thrust into the earth, the tilling claws 32 and 32 of the extending member 16a on the other side are placed in air. Thus, the fluctuations in the impacts of the tilling claws on one side are always compensated with the cases, etc., on the other side. The intermediate shaft 17 is rotated at a high speed, thereby permitting to improve the efficiency of the work.
