Title: Vacuum cleaner
Inventor: HIRANO HIDENORI
IPC: A47L7/04
Filed: 1994-12-22
Abstract: PURPOSE: To provide a vacuum cleaner in which hot air is easily circulated with a simple construction by providing a pressure valve element which opens in response to an increase in negative pressure in a dust collecting chamber formed in a circulation air duct. CONSTITUTION: When an electric-powered blower 25 is driven in a state where a holding section 14 or the end of an extension tube is closed, negative pressure in a dust collecting chamber 19 is increased, and negative pressure in a circulation air duct 7 which opens to a suction opening 47 of the dust collecting chamber 19 is similarly increased. By such an increase in the negative pressure, the difference between the pressure in an electric-powered blower chamber 20 and that in the circulation air duct 7 which are partitioned by a pressure valve element 50 becomes large. A force which energizes a valve element 54 of the pressure valve element 50 toward the circulation air duct 7 by atmospheric pressure in the electric- powered blower chamber 20 acts.  When the negative pressure in the circulation air duct 7 reaches a predetermined value, the valve element 54 is moved toward the circulation air duct 7 side by the atmospheric pressure of the electric-powered blower chamber 20 against the energization of a coil spring 55. A through hole 52 of a valve seat 53, which has been closed by the valve element 54 is opened, and hot air which is exhausted into the electric- powered blower chamber 20 is flowed into a dust collecting bag 22 via the circulation air duct 7, a communication hole 74, and a connection tube 69.

Title: Remote registering system
Inventor: FUKUI KATSUHIKO
IPC: G06F17/30
Filed: 1989-12-13
Abstract: PURPOSE:To register and retrieve pictures up to the maximum of A1 size by performing negotiation in a session layer with a dummy picture size at the time of transmission of a picture larger than the size determined in a facsimile transmission protocol. CONSTITUTION:After line connection, terminals refer to the maker code in a main command parameter by session setting 8a to discriminate mutually whether opposite terminals are a general facsimile or an electronic filing device. When the opposite party is an electronic filing device, information indicating the transparent mode and information required for this mode are added after the maker code to perform negotiation. Negotiation is performed with standard value A4 as picture size information by option function negotiation 8b of the next sequence. Thus, not only pictures having A1 and A2 sizes but also data like title information is transmitted since data transmitted hereafter is regarded as picture data having A4 size independently of contents, the data size, etc.

Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To increase a data transfer speed by making the maximum value of a seeking time small for recording/reproducing time sequential data such as a video signal or an audio signal in a disk storage medium. SOLUTION: A harddisk is divided into, for instance four segments S1 to S4 and, while write segments are sequentially switched, video/audio information is written. That is, data 1 of time t(0) is first written in the head address 0 of the segment S1 located in the outermost periphery. Then, data 1 of time t(1) is written in the head address 1 of the segment S2. Hereinafter, similarly, data of t(2) is written in the head address 2 of the segment S3, data of t(3) in the head address 3 of S4, data of t(5) in the second address 5 of S4 and data of t(6) in the second address of S3, and while the segments are sequentially changed for writing like this, and when data is written in the segment of the innermost or outermost periphery, the changing direction of the segments is inverted and data is written.  Thus, the maximum value of a seeking time is reduced to 174 for writing data in continuous addresses.

Abstract: PURPOSE:To test a liquid through simple operation by providing a containing member which is at least partly transparent and can accommodate a solid testing agent and an inflow hole of a liquid to be tested at an end of said containing member which is the size not to pass said testing agent. CONSTITUTION:A containing member 1 is formed of plastic in a generally cylindrical shape. An upper end of the member 1 is cut with right angles to the elongated direction thereof and a lower end thereof is cut with an inclination of about 45 deg. to the elongated direction. An upper sealing part 2 and a lower sealing part 3 are formed respectively at the upper and lower ends of the cylindrical member 1, whereby the interior of the member 1 is tightly sealed. A spherical testing agent 4 having the diameter about half the member 1 is placed inside the member 1. The testing agent 4 is hooked halfway by the sealing part 3 when the testing agent 4 stands up. Thereafter, an inflow hole 6 is formed in the size not to pass the testing agent 4 by cutting the lower part of the sealing part 3. While the air inside the member 1 is partly discharged by pressing the center of the member 1, the hole 6 is dipped in a liquid 8 to be tested. Then, the member 1 is released from being pressed. Accordingly, the member 1 is returned to the original state by the elasticity, whereby the liquid 8 is sucked inside the member 1 through the hole 6. The testing agent 4 is soaked in the liquid 8. Thus, the liquid 8 can be tested through reaction between the agent 4 and the liquid.

Title: Wheel crane
Inventor: MIYAZAWA HIROSHI
IPC: B66C23/66
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To secure a large approach angle by holding an auxiliary hook in a high position, to install a long size jib, and to improve cargo hanging capacity by the jib by fitting one side part of the auxiliary hook to a front part of a main hook housing metal fitting. SOLUTION: One side part of an auxiliary hook 8 is rotated at a large turning angle so as to enter the inside of the front side of left/right side plates of a main hook housing metal fitting 10 to be housed on the lower side of a boom head 2. Thus, when a wheel crane is put in a traveling posture, the lower end of the auxiliary hook 8 is positioned on the upper side more than an approach angle line La, and since a height up to the auxiliary hook lower end from aboveground is high, even if the hook is adopted for the wheel crane becoming a traveling posture in a forward inclined state where the tip of a boom becomes lower than the base end side, a height up to the walk hook lower end from aboveground can be heightened.  That is, since an approach angle of the wheel crane in the traveling posture is large, the lower end of the auxiliary hook does not contact with a road surface when starting slope climbing travel.

Filed: 1993-12-22
Abstract: PURPOSE:To increase the conversion efficiency of a step-up/down converter by changing the on-duty ratio of a pulse signal to be supplied to a first switching element which is connected in series with an inductance element. CONSTITUTION:When a pulse signal(PS) which is output from a terminal OUT1 of a regulator 4 is at an H level, a transistor(Tr) Q3 is turned on and a current supplied by the regulator 4 is supplied to a TrQ7 through the TrQ3 and a resistor R2. As a result, a voltage is applied to a switching element(SW) Q1 through the TrQ7 and then the SWQ1 is turned off. When the PS is at an L level, on the other hand, the TrQ4 is turned on and the gate of the SWQ1 is grounded through a diode D2 and the TrQ4 and then the SWQ1 is turned on. When the level of the PS turns from L to H, the TrQ3 is kept off and the SWQ4 is kept on until a capacitor C1 which has discharged during the time when the PS is at the L level (during the extended period of time) is changed, although the PS is at the H level. As a result, the TrQ7 is kept off and the SWQ1 is kept on during the extended period of time.
