Title: Operating method of inverter controller for layer-driving motor of glass-manufacturing equipment
Inventor: KASAHARA HIDEFUMI
IPC: C03B25/04
Filed: 1991-07-22
Abstract: PURPOSE:To prolong an operating time by limiting a running speed command in proportion to an input voltage at the time of the input voltage drop of an inverter controller accompanying a battery voltage drop during service interruption. CONSTITUTION:The rated speed of a motor 1 is considered as N1; a voltage drop by a wiring between inverter 2 and motor 1, as V2; and an inverter input voltage necessary for outputting the rated primary voltage of an engine, as V3. In the operation by a battery 4 during service interruption, an inverter input voltage V4 is detected by a voltage detector 7 and a computing element 8 calculates the maximum running speed signal N2 by the equation. A signal preferrer 11 gives the inverter 2 the smaller one out of the preset speed signal 10 from a speed setter 5 and the maximum running speed signal (N2) as speed signal. As a result, a motor exciting current can be maintained at a constant value and an operating time can be prolonged.

Title: Paper sheet conveying mechanism
Inventor: OKAMOTO YOSHIYA
IPC: B65H3/06
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To detect a conveying amount of recording paper in detection delay time of a paper sheet sensor accurately to obtain the length of recording paper correctly in a paper sheet conveying mechanism in which recording paper is conveyed intermittently. SOLUTION: The number of conveyance steps in paper sheet conveyance from the time when a tip of recording paper is detected by a paper sheet sensor (S2: YES) to the time when a rear end thereof is detected is counted by a counter (S3), and the number of conveyance steps in detection delay time of the paper sheet sensor is stored in a RAM at the same time. When the rear end of recording paper is detected (S5: YES), the number of conveyance steps stored in the RAM is subtracted from the number of conveyance steps by this counting to obtain a length of recording paper (S8). As a result, a detection error of the length of recording paper caused by detection delay time of the paper sheet sensor is compensated even in a system in which recording paper is conveyed intermittently.

Inventor: IWAGANE TAKANOBU
IPC: H02P29/00
Filed: 1981-12-21
Abstract: PURPOSE:To correct the gain of a speed amplifier automatically by giving a motor a predetermined torque command in a short time, varying the proportional gain of the speed amplifier in response to the quantity of variation of speed during that time and keeping the transient response of the speed control system constant. CONSTITUTION:A changeover switch SWO is connected to a contact 201 only when the position of a contact 202 is given the torque command Etau (Es is the line voltage of the command) under normal operation. Switches SW1, SW2... are each used for changing over the gains of the speed amplifier 2. A sample holding circuit 6 transmits the output to a switch changeover mechanism consisting of the level comparator 7 of speed feed-back signals Nfb and a memory 8. The transmitting signal level and the level set value E1, E2... of the mechanism are compared, and the ON-OFF of the switches SW1, SW2... is selected. Accordingly, the most excellent transient response can be obtained at all times even when the motor plus load torque of a driving system are varied.

Title: Leakage oil detection of oil filled cable line
Inventor: MURAKAMI KAIHEI
IPC: H02G15/26
Filed: 1988-08-19
Abstract: PURPOSE:To detect a leakage oil accident in early stages and to reduce the influence by spillage oil to the minimum by giving an alarm when the current flowing to the current detection element exceeds the set value. CONSTITUTION:Three-terminal resistance-type converters 1'A, 1'B and 1'C are provided in oil feeding tanks of each phase and with each intermediate variable terminals 2A, 2B and 2C the supply voltage E is divided at the resistance ratio in proportion to the oil quantity or oil pressure in the oil feeding tanks. If the intermediate variable terminals 2A to 2C for three phases moves just in the same way with the same change of oil quantity in the oil feeding tanks, the divided voltage of the supply voltage E by the resistance remains the same for three phases and no current flows. However, in case only the intermediate variable terminal 2A of the converter 1'A makes a change more than others by a diff portion, the divided voltage Ea will be larger than the other divided voltage Eb and Ec and the current will flow. By detecting the current flow by a current detection element ZAB, the leakage oil is detected and an alarm is given.

Title: Cache memory control system
Inventor: KITAHARA TAKESHI
IPC: G06F12/08
Filed: 1990-08-06
Abstract: PURPOSE:To improve the performance of a whole system by reflecting latest data on another Cm even if there is writing in an entry concerned in a self memory after the entry is transferred to the other Cm at the time of controlling respective cache memories (Cm). CONSTITUTION:When there is access from another Cm to an area which a self memory holds, which is rewritten but which is not reflected on a shared memory CM yet, the cache memory (Cm) M1 of a copy back system suppresses the response of the shared memory for access and transfers the entry concerned to the other Cm. since CmM1 and the other Cm share same data, a shared state instruction flag S is turned on. When there is writing in the entry concerned, CmM1 transmits a write address to a system bus. Thus, other Cm detects the new writing of data in the entry concerned which is transferred immediately before and it invalidates it. CmM1 turns of the flag S since data which is written latest and data before it in the entry concerned become dissident. Thus, latest data in CmM1 is reflected on another Cm and performance of the whole system can be improved.
