Title: Hydraulic circuit of cylinder
Inventor: FUJITA HIROSHI
IPC: F15B11/22
Filed: 1982-10-01
Abstract: PURPOSE:To eliminate a member connecting piston rods and obtain a light weight device by a method wherein a single rod type double-acting cylinder and a single acting cylinder are synchroneously operated with one manual hydraulic pump. CONSTITUTION:Since the area in which the sectional area S2 of a piston rod 53 is subtracted from the inner diameter area S1 of a double-acting clinder 50 is equal to the inner diameter area S3 of a single acting cylinder 50a, the raising speed of the piston rod 53a of the single acting cylinder 50a pushed up by an operating hydraulic oil discharged from the double acting cylinder 50. Therefore, the lifting blocks 3, 3 connected to both cylinders 50, 50a are raised simultaneously in the same speed is equal to that of the piston rod 53 of the double- acting cylinder 50. Hydrualic oil of the same volume as that of discharged hydraulic oil is suctioned into the upper chamber 57 of the piston from the single acting cylinder 50a, resulting in that both piston rods 53 and 53a are descended simultaneously under the same speed.

Filed: 1993-06-22
Abstract: PURPOSE:To obtain an image excellent in reproducibility for fine lines and resolution for printing of characters by using a surface-treated magnetic material, incorporating the magnetic material in a specified range of pts.wt. to polymerizable monomers, and incorporating a release agent in a specified range of pts.wt. to the monomer. CONSTITUTION:This magnetic developer is directly obtd. by suspension polymn. of a monomer compsn. containing at least polymerizable monomers, magnetic material and release agent in a water-base medium. The magnetic material is incorporated by 20-70 pts.wt. calculated as untreated magnetic material to 100 pts.wt. of polymerizable monomers. Namely, if the amt. of the magnetic material is lower than 20 pts.wt., electrification characteristics decrease. If it exceeds 70 pts.wt., the amt. of the magnetic material is so large to decrease electricification property. The amt. of the release agent is 10-40 pts.wt. to 100 pts.wt. of polymerizable monomers. If the amt. of the release agent is lower than 10 pts.wt., the releasing effect of the toner decreases. If it exceeds 40 pts.wt., granulating property of the toner during production decreases and the obtd. toner shows deterioration of blocking property.

Abstract: PURPOSE:To reduce the fruitless use of a recording area by writing synchronizing signals and address information in an n-time superposed state at every pre-format section and at the same time, additionally recording number information indicating the order of the synchronizing signals in the same pre-format section. CONSTITUTION:The rotation of a disk 1 is controlled by a control section 3 and clocks from a rotation detecting section 4 indicating the rotating state of the disk 1 are counted by means of a counter 5. The data of the counter 5 are sent to a pre-formatter 6 and the pre-formatter 6 produces synchronizing signals SYNC and identification code ID (n) times and at the same time, outputs the number of synchronizing signal writing times to a modulator 7 when the pre-formatter 6 produces pre-format data based on the data of the counter 5.

IPC: A62C37/40
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To realize quick and reliable fire fighting regardless of existence of partition by detecting the existence of partition for dividing a space under surveillance, selecting a plurality of discharge guns mounted at the both sides of the partition when a fire is broken out, in case the partition is detected, and controlling the discharge guns in a dischargeable state. SOLUTION: In the case of application to a ballpark 21, a space under surveillance 22 is divided into a plurality of blocks 23, and discharge guns 3E to 3H, each taking charge of each of first to fourth divided spaces 22A to 22D, are arranged outside the divided spaces 22A to 22D. For example, if a fire is detected by a fire detector 1D, the origin of fire is calculated on the basis of information on the origin of fire, a predetermined block corresponding to the origin of fire, for example 23D, is distinguished, and a discharge gun 3H to take charge of a relevant divided space 22D is selected.  Further, in case the space under surveillance 22 is divided with mounting a partition comprising a partition curtain 24, discharge guns at the both sides of the partition curtain 24 are selected at the same time or successively, if the origin of fire is judged to be inside an area of partitions at the both sides of the partition curtain 24.

Title: Medium carrying mechanism for printer
Inventor: TAMURA HIDEKI
IPC: B65H5/06
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To make a medium produce no warp and to eliminate the jammed or skewed medium and thus to produce correct printing by mounting a predetermined numbers of tapered press rollers such that their tapered surface faces to inside and by carrying the medium under outward tension. SOLUTION: Rollers 2, 4 and tapered rollers 17, 18 are rotated with a meduim being pinched. Since the tapered rollers 17, 18 are rotated in a state in which the contact parts thereof are crushed by the pressing forces of springs 19, 20, the rotating forces pull the medium outward. Since the medium runs in a carrying direction while they are pulled outward by suitable tension, the medium does not produce a warp between a press roller 15 and the tapered rollers 17, 18, thereby eliminating the jammed or skewed medium. The outward tension can be adjusted by changing the angle of taper or the pressing force of the spring.

Title: Cable length measuring system for loop network
Inventor: SHOJI NOBORU
IPC: G01B11/02
Filed: 1991-07-16
Abstract: PURPOSE:To measure a length of a cable without stopping a network system by measuring a time of a packet from being looped back from a node equipment till being returned to a montor equipment so as to measure the length of the cable connected between equipments. CONSTITUTION:A monitor equipment 1 allows a node equipment 3 to cause loopback operation to send a signal packet to the operating system. The signal packet is sent to a node equipment 2 through cables 11, 12 and inputted to the node equipment 3. Then a loopback is caused and the packet is looped back to a standby system, the packet is sent to the standby system of the node equipment 2 through cables 21, 22 and returns to the standby system of the monitor 1. Then the monitor 1 measures the delay time after the signal packet is sent to the operating system till it returns to the standby system. The time resulting from subtracting a delay time of the operating system, the standby system of the node equipment 3 and the loopback from the measured delay time is divided by a delay time of the cable per unit length to obtain the length of the cable. Then the length of the cable is measured without stopping the network system.
