IPC: E21D9/087
Filed: 1987-06-30
Abstract: PURPOSE: To contrive effective propulsion by arranging a disc cutter provided with a self-sharpening function cutter and a cutter bit so as to help each other for hard crushing, providing a soil-intake opening taking in only soil at the front face, and equipping a scraper at the front end of a driving shaft. CONSTITUTION: A flat face plate 7 on which disc cutters 5, 6 and cutter bits 81 -86 , 91 , 92 , 101 , 102 are equipped in a cutter head dome 1. Crushed sand and soil are transferred from soil-intake openings 11-13 to a scraper 14 by these bits and discharged rearward by a screw 4 having blades attached to the drive shaft 3 without choking soil in the frame. The outermost peripheral cutter edge of the disc cutters 5, 6 has a shape for self-sharpening function, and a gravel caught in the soil-intake opening is crushed by the rotation of disc cutters 5, 6 to be taken in the cutter head 1. In this way, the cutter head can be used without choking even in case of clayey soil.

Title: Dynamic random access memory
Inventor: KIKUCHI SHUJI
IPC: G11C29/14
Filed: 1994-07-13
Abstract: PURPOSE:To perform mode switching in a short time by applying super Vcc to a specific pin and performing WCBR cycle, preventing mis-entry by a user by shifting from a normal mode to a vendor test mode, and unnecessitating applying Vcc after entry. CONSTITUTION:Super Vcc is applied to a specific pin, and WCBR cycle is performed. Shifting to a vendor test mode is specified by a data group address key given to an address pin at this time. Once, performing entry for a vender test mode, applying super Vcc is needless. Also, when it is reset to the test mode previously decided during entry, retuned to the normal mode. In the other entry system, entry conditions for the vendor test are same as in the past, WCBR cycle is performed for entry for a second level mode by only specifying the address key, and applying super Vcc is needless. In order to return to a submode from a sub-mode, WCBR cycle may be performed by giving the specific address key. The same way is performed to return to the normal mode.

Title: Belt protecting device for vehicle air-conditioner
Inventor: KURAHASHI YASUFUMI
IPC: B60H1/32
Filed: 1986-07-10
Abstract: PURPOSE:To enhance the reliability of protection of a belt, by determining a set time for a delay circuit in accordance with the rotational speed of an engine so that the lower the rotational speed of the engine is, the shorter the delay time is, in order to rapidly detect an abnormality in a compressor during low speed operation of the engine. CONSTITUTION:When the rotational speed of a compressor lowers, the relative relationship between the output voltages of F/V converters 8, 12 corresponding to an engine rotational speed signal source 4 and a compressor rotational speed sensor 9, is reversed. Further, a comparator 13 detects this reversal to stop the compressor by means of an output circuit 6 and an electromagnetic clutch. Further, during normal rotating operation of the compressor, when a detection value by an evaporator temperature sensor 1 exceeds a predetermined value, a thermocircuit 2 delivers a signal for turning on the electromagnetic clutch, to the output circuit 6 and also to a delay circuit 15. Further, the delay circuit 15 actuates the comparator 13 in accordance with a delay time which is determined in dependence upon the rotational speed of the engine.

Filed: 1989-06-22
Abstract: PURPOSE:To eliminate the need for discharging a transmission original by returning the transmission original placed at an original read position to an automatic paper feed section in the case of redial waiting. CONSTITUTION:A transmission original set to an original platen 21 has its tip at an automatic paper feed section 23, a destination facsimile telephone number is inputted from a ten-key 1e and a communication switch is depressed, then a mechanism management section 12 starts the movement of the transmission original. When the arrival of the original tip to an original read position 29 is detected, the carriage of the original is stopped and a communication management section 15 executes the call setting and a pre-message protocol. In the case of awaiting redialing, a redial original management section 13 gives a request of returning the transmission original at the original read position 29 to the mechanism management section 12 and the mechanism management section 12 returns the tip of the transmission original to the automatic paper feed section 23. Thus, discharge of the original is not required, the communication disable time with an opposite facsimile equipment is reduced and the clear indication of unfinished transmission and the replacement of the transmission original are facilitated.

Title: Digital-to-analog converter
Inventor: ARAI HIROMI
IPC: H03M1/78
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate output even to the multibit input by preparing a 1st D/A conversion part which flows a constant current to a resistor ladder part of an R-2R system in response to the input bit and a 2nd D/A conversion part which flows plural constant currents after the conversion of bit number by defining the MSB side of the resistor ladder part as the load and obtaining the analog output from one of both ends of the load of the MSB side. SOLUTION: A 1st D/A conversion circuit 2 of an ordinary R-2R system consists of a resistor ladder 3 including the LSB through 6 bits, the bit switches 4A to 4F and the constant current sources 5A to 5F which flow a constant current I respectively.

Title: Injecting device for tracer gas used for flow rate measurement of gas in pipe
Inventor: NAKAGAWA FUTAHIKO
IPC: G01F1/704
Filed: 1984-08-03
Abstract: PURPOSE:To obtain an accurate flow rate of gas by injecting tracer gas into the gas in a pipe from a tracer gas container, calculating the injection amount of the tracer gas from a decrease in the weight of the tracer gas container, and detecting the concentration of the tracer gas in the mixed gas. CONSTITUTION:The gas flows in the pipe P as shown by an arrow G. The tracer gas T is injected into the pipe P at the upstream side from the pressure container 1. The tracer gas T is mixed with the gas and the mixed gas MG is sampled at the downstream side to detect the concentration of the tracer gas. At this time, the weight of the pressure container 1 is measured at constant intervals of time and the injection amount of the tracer gas is calculated from a decrease in the weight. Then, the flow rate of the gas is calculated from the relational expression between the tracer gas concentration and injection amount. Thus, not only the tracer gas concentration, but also the injection amount is detected accurately and the flow rate is calculated from the relational equation, so the gas flow rate is measured with high precision.

Abstract: PURPOSE:To reduce the number of parts and make an easy control possible by composing pushup means of drive plates, follower plates capable of stroking, and latching means for allowing relative motion of the drive plates to the follower plates for the stroke. CONSTITUTION:In moving up first and third pushup plates 22a, 24a of drive plates, second and fourth pushup plates 23a, 25a of follower plates are moved up at the same time. Latching means are composed of engagement members 42 consisting of springs for energizing ball bodies toward sides at positions for holding the pushup plates at the highest level facing the positions of counter members on the sides of the pushup plates 23a, 25a, so the pushup plates 23a, 25a are held at the highest position when they get there, and when they lower for a stroke set by the pushup plates 22a, 24a, the pushup plates 23a, 25a are lowered to release the engagement to lower them. Delay action is thus enabled, and drive means is simplified, thereby control becomes easy.
