Title: Elevator
Inventor: ISHIKAWA YOSHINOBU
IPC: B66B9/02
Filed: 1995-02-03
Abstract: PURPOSE: To move plural cars in a elevator shaft by installing a differential mechanism having an engaging means with wire ropes and a speed change mechanism installed on this differential mechanism for prescribing a speed ratio of a car between upward moving wire ropes and downward moving wire ropes. CONSTITUTION: Plural ring shape wire ropes are moved at a constant speed by a drive device 12 installed on a building 13 and moved facing to upward/ downward mutually and returned back at the upper/lower parts of an elevating road 13a. A speed change mechanism for prescribing a speed ratio of wire ropes moving upward/downward for a car 11 is installed in the differential mechanism installed on the car 11. As plural wire ropes are moved at a constant speed, the car 11 is elevated upward/downward in order that the speed ratio of the wire ropes moved upward/downward for the riding cage 11 becomes a regulation. After all, the car 11 is elevated by the motive power from the drive device 12 through the speed change mechanism. In other words, the upward/downward motion of the car can be controlled by the change of the speed ratio of the speed change mechanism.

Title: Manufacture of elastic surface wave element
Inventor: SHINKAWA TOMOHIKO
IPC: H03H3/08
Filed: 1979-02-15
Abstract: PURPOSE:To ensure the frequency control by removing the surface of the zinc oxide layer used as the piezoelectric substance by the dry etching and thus adjusting the thickness of the layer. CONSTITUTION:The vacuum degree within container 6 is set to 10<-10>-10<-3> torr, and the gas within container 6 is changed into the plasma via the high frequency sent from FR power source 9. And then the ion which is accelerated by the electric field caused near target 8 is put vertically to the surfaces of zinc oxide layers 3 and 5 of elastic surface wave element 12. In such way, the surfaces of layer 3 and 5 are removed gradually. In that case, if element 12 is made active previously, the frequency varies according to the thickness of layers 3 and 5 each. And this frequency change is monitored directly through frequency measuring instrument 13. Accordingly, the desired frequency is obtained by removing zinc oxide layer 5a while confirming instrument 13. As a result, the frequency dispersion can be exteremely reduced.

IPC: H01L21/208
Filed: 1982-02-05
Abstract: PURPOSE:To enable multilayer growth having a composition according to expected set value by sucking and removing a melting liquid used for the growth of each layer from the upper section of a substrate crystal when the growth is completed and preventing carry-in to a new melting liquid for growth of the melting liquid being used. CONSTITUTION:When a first layer is grown, the suction port of a melting-liquid suction pipe 7 is positioned to the upper section of the melting liquid 4. When the growth of the first layer is completed, the suction port of the suction pipe 7 is inserted into the melting liquid 4 prior to the sliding of the substrate crystal 3 for contact with the second melting liquid 5, and the melting liquid 4 is sucked. The melting liquid 4 sucked is stored into a melting-liquid reservoir 8 formed to one part of the suction pipe 7. Accordingly, when the melting liquid 4 is removed from the upper section of the substrate crystal 3 and the substrate crystal 3 is slid so as to grow a second layer, carry-in to the melting liquid 5 of the melting liquid 4 is prevented. Liquid epitaxial growth through which the melting liquids are not carried in is enabled by similarly sucking and removing the melting liquids from the upper section of the substrate crystal even in case of the completion of the succeeding growth of the second layer and a third layer.

Title: Ignition device
Inventor: SATOU MUNEKAZU
IPC: H01T15/00
Filed: 1979-02-16
Abstract: PURPOSE: To secure simplicity, reliability and cost reduction of peripheral controlling devices by providing a time to control the sparking time of an ignition spark.  
     CONSTITUTION: On turning a switch 2 ON, DC voltage smoothed by a capacitor 15 and a resister 14 is applied to the anode side on n-gate thyristor used for a timer, while DC voltage smoothed by the capacitor 15 and the resisters 13, 14 is applied to the gate. Since the gate voltage is higher than the anode voltage as actuating n-gate thyristor 11, n-gate thyristor 11 becomes OFF condition. Consequently, the gate voltage of the thyristor 7 is normally operating to discharge the charged electric charge of the capacitor 6 through the primary winding of a high voltage generating transformer 5, which develops the high voltage for the secondary winding.

IPC: H02H3/04
Filed: 1984-02-02
Abstract: PURPOSE:To take countermeasures to a power failure and a thunderbolt by printing the level of the ground current of a power transmission line, the current distribution of an aerial earth wire, and the level and direction of a short-circuit current at distance, and reading the passing state of an accident current at a position which is distant to some extent. CONSTITUTION:Coils L1-L3 are grounded each at one terminal, and capacitors C1-C3 are connected between the other-side terminals and ground. Then, only zero-phase current components are extracted by variable resistances VR1-VR3 and fixed resistances R1-R3 and amplified by an amplifier AMP1, and then light is emitted by a light emitting diode LD1. Further, amplifiers AMP2-AMP6 amplify signals of the coils L1-L3 and current transformers CT1 and CT2. Then, the output of a voltage detection rod VP is passed through an arrester AL, resistance R6, diode D3, and amplifier AMP7 to generate a pulse P. If an accident occurs, the voltage detected by the detection rod VP varies in level and phase angle greatly, so the phase of the accident current is detected securely. Then the obtained data is computed by a computer and the result is printed out to estimate the distance to the accident point.

Title: Safe circuit for balance cargo handling device
Inventor: TOMARU HITOSHI
IPC: B66D3/18
Filed: 1988-01-28
Abstract: PURPOSE:To ensure safety, by a method wherein when the absolute value of a differential signal from a force detector exceeds some threshold and the absolute value of a signal from a speed detector exceeds some threshold, balance operation is stopped once. CONSTITUTION:When balance operation is selected, a safe circuit motioned in linkage with a speed command selecting circuit stops balance operation once when the absolute value of a differential signal Fe inputted from a force detector and the absolute value of a signal theta' from a speed detector respectively exceed some threshold. Simultaneously, a signal theta, a speed signal theta', and an acceleration signal (a) from a position detector are fed back to a speed command computing circuit. A force negative feedback gain K by which a difference between the force detecting signal Fe and a load memory value Wphi is multiplied is decreased for control, and the sudden motion of a cargo is prevented from occurring. Besides, when the absolute value of (wphi-Fe) is continuously low for a given time, the gain K is returned to its original value, and when it is high, the stop of balance operation is decided. This constitution enables prevention of the occurrence of a risk, e.g., jumping, drop.
