Title: Vane pump
Inventor: TSUCHIYA KEIJI
IPC: F01C21/10
Filed: 1981-06-10
Abstract: PURPOSE:To raise the volumetric efficiency of a vane pump, by reducing leakage of oil by increasing the sealing area at the position where a cylindrical rotor is held in sliding contact with the inner surface of a cam-shaped cylinder, by constituting the inner surface of the cylinder with cycloidal curves connected to each other, and shaping the inner surface of the cylinder at the regions near the contact lines between the rotor and the inner surface of the cylinder to have  arcuate sealing surfaces. CONSTITUTION:The inner surface 6a of a cam-shaped cylinder is constituted with six cycloidal curves connected to each other at the intervals of pi/3. By employing such an arrangement, it is enabled to lower the differential value dR/ dtheta near three sliding contact lines (theta=0.2pi/3.4pi/3) formed between the inner surface 6a of the cylinder and the outer surface of a cylindrical rotor 1 (where R is the moving diameter and is equal to a+d/2+d/2Xsin(3theta-pi/2)), and substantially area seal can be obtained instead of line seal at the contact regions, so that the volumetric efficiency can be raised since leakage of oil can be reduced. Further, since dR/dtheta and d<2>R/d<2>theta are both zero at each connecting point of the cycloidal curves, vanes 3 can be moved smoothly along the inner surface 6a of the cylinder.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To select only an object possible to be displayed in accordance with the target of a user by providing a calculating means that finds a minimum rectangle including a section of a selection object and a section where a main object exists. SOLUTION: A calculating means divides plane coordinates on which an object is arranged into reticulated sections and finds a minimum rectangle including a section of a selection object and a section where a main object exists among rectangles being equal to the size proportion of a displayed image composed of plural sections. A selecting means selects an object included in the section of the selection object based on the found minimum rectangle and a selection condition. For instance, in a map data retrieving device, a scale calculating part 16 finds a minimum rectangle including the block of a selection object and a block where a main object exists. Then, it selects an object satisfying a display condition and stores it in a personal object storing part 21. When a map is displayed, the object is selectively read from the part 21 and displayed.

Filed: 1981-06-10
Abstract: PURPOSE:To obtain the fetching of high frequency and the transmission of high speed of a process signal, by providing a first-in and first-out memory for transmission and reception for a transmission control section of a local station. CONSTITUTION:In a DMA transfer from a local station LST3 to a master station MST, when a DMA request signal is generated from a DMA controller 14, a DMA permission signal is outputted from a main processor 7. In this case, the transmission data from a main memory 9 is transferred to a first-in and first-out FIFO memory 28 for transmission together with access time t1/memory access time t2 words to an input and output section 10. In making data transmission from an MST to an LST3, if the processor 7 is under execution of the input and output instruction, a plurality of words of information is stored in a reception FIFO 27 automatically, data processing is made after the end of input and output instruction to the memory 9. Thus, the data transmission between the LST and MST is transmitted in the t2 per work for high speed transmission.

Title: Recessed part with bar for aerodynamic sound reducing structure
Inventor: AZUMA AKIHIKO
IPC: B60R13/02
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce aerodynamic sound generated by a recessed part with a bar, formed over the surface of a substance exposed to an air flow high in speed. SOLUTION: In case of an air flow F running along the surface S of a substance in the direction crossing the bar body Q provided for a recessed part P formed over the surface S of the substance, a projected streak T in an rectangular equilateral triangle shape in cross section, is provided in the vicinity of the opening part (r) of the recessed part P at the upstream side of the air flow F in the surface S of the substance along the bar body Q. By this constitution, the air flow F is sprung upward by the projected streak T, consequently, the level of aerodynamic sound generated by the recessed part with the bar is thereby lowered much. The forming position of the projected streak T may be parted from the opening part (r) of the recessed part P, but it is disposed to a place close to the opening part (r) if possible.  It is more effective if it is aimed at a reduction in aerodynamic sound generated by the substance moved at high speed, to apply the aforesaid constitution not only to the rolling stock but also to an automobile such as a truck and the like.

Title: Flow rate measuring device
Inventor: SHIBA BUNICHI
IPC: G01F1/00
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To enlarge a flow rate measuring area by use of plural flow passages. SOLUTION: A fluid entering from an inflow passage 1 passes through an opening/closing means 4 which is open, and its flow rate is measured by a measurement means 5. The measurement means 5 is controlled by a control means 6. When all of plural flow passages 3 are opened, the fluid flows at a large flow rate, which can be measured; when only one of the flow passages is opened, small flow rate can be measured. Thus, from micro to large flow rates can be measured at high speed with accuracy by increasing or decreasing the flow passages.

Filed: 1978-07-20
Abstract: PURPOSE: To obtain good cleaning effect without complicating a device, by applying proper different voltages in developing and cleaning in a copying method using a one-component type developer consisting mainly of a nonmagnetic toner.  
     CONSTITUTION: In the copier using a nonmagnetic one-component type toner and operating development and cleaning in the same device, developing bias voltage VS to be applied to roller 7 in developing is made positive like an electrostatic latent image and the difference between voltage VS and voltage VN is made smaller than development start voltage VK. On the other hand, toner supplied from hopper 8 is negatively charged by voltage VE of charge injection ielectrode 9 and moves to the image section of drum 1 kept at higher voltage VI than that of roller 7, thus the latent image is developed. In cleaning, the difference between lowered voltage VI' and constant bias voltage VS is set to a value lower than voltage VK, voltage VE to be applied to electrode 9 is made positive, thus permitting the difference between voltages VE and VS to be reduced, the charge amount of the toner to decrease, attachment to drum 1 to be prevented, and further, the residual toner on drum 1 to be removed with roller 7 for cleaning.

Title: Two-cycle engine equipped with scavenging pump
Inventor: YAMAMOTO MASAHIRO
IPC: F02B75/02
Filed: 1981-06-09
Abstract: PURPOSE:To prevent lubricant constituent from mixing with newly charged air, by separating a suction passage from a crankcase, by providing a scavenging pump to a suction passage, which is connected with the scavenging port of an engine, and by revolving the pump at the same speed as that of a crankshaft and to the reverse direction to the crankshaft. CONSTITUTION:A scavenging pump 21 is turned to a direction B by a crankshaft 7 which is turned to a direction A, by the intermediary of a driving gear 27 and a follower gear 26, while an engine is operated. Accordingly, the scavenging pump 21 sucks fresh air through a suction passage 17, and feeds it into a pre- compression chamber 16, after pressurizing it. When a scavenging port 15 is opened, accompanied with the descent of a piston 3, the pressurized air reserved in a pre-compression chamber 16 flows into a combustion chamber 4, pushing combustion gas out to an exhaust port 14, to scavenge the air from a combustion chamber 4. When a piston 3 reaches a top and a bottom dead points, the  position of a gravity of a scavenging pump 21 and a counterweight 13 come to the opposite side to a piston 3, which offsets a reciprocating inertia force of a piston 3.
