Title: Scroll compressor
Inventor: KAWANO ISAMU
IPC: F04C18/02
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To reduce a clearance between a chip seal and a scroll bottom surface so as to reduce leakage of compressed air by providing a step difference shorter than the bank part of the groove of the teeth tip of a lap on the bottom surface of a scroll, and heightening the height of the step difference to the extent which is not brought in contact with the teeth tip of the lap.

A step difference 9 is arranged on the root part of the scroll lap 10 of the other scroll at a few clearance between the bank part 8 of the groove 12 and the side surface of the chip seal 6. It is thus possible to reduce a clearance so as to prevent leakage of compressed air.

Filed: 1989-12-11
Abstract: PURPOSE: To obtain the best estimate value of an output frequency having no error by using a certain concept from Bresenham Line algorithm and forming digital dividers for supplying the best estimated output frequency achieving fout = X/Yfin and 0<Y/X<=1. CONSTITUTION: Latches 2 and 3 being the dividers receive and hold binary data representing a binary X and Y. An X-value of the latch 2 is represented in negative form of a complement of 2. The X-value is composition with the value of 0 before supplied to an adder 6 in a block 4. The adder 6 outputs a summation INCR which has either a value Y or Y-X to the respective sign signal values of 1 and 0. The INCR value, i.e., Y or Y-X is further added to a numeral representing the result of immediately before iteration in an adder block 7.

Abstract: PURPOSE:To provide a ceramic heater of high durability capable of continuous operation over a long time at high temperature by electrically connecting and fixing a ceramic heating body to a terminal rod with edges faced to each other via an electrode takeout fitting. CONSTITUTION:When a ceramic heater 1 is used as an assist heater for an internal combustion engine, a cylindrical fitting 5 is first coupled to a ceramic heating body 4 having an exothermic resistor 3 of inorganic conductive material buried in a sintered body 2 of silicon nitride.

Title: Glass rod for porous glass preform
Inventor: KUWABARA MASAHIDE
IPC: C03B37/018
Filed: 1992-11-04
Abstract: PURPOSE:To obtain an engaging part having high strength and uniform quality at a low cost by drawing the upper end of a porous glass rod under heating to reduce the diameter and using the narrowed part as the engaging part for suspension. CONSTITUTION:Conventional method for suspending a porous glass preform is the opening of a pin-insertion hole through a glass rod or the formation of a notch to form a suspension part. Recent progress of technology enabled the production of a large-diameter preform and the hazard of the breakage of the suspension part by the weight of the preform is increasing. In the present invention, the upper end of a glass rod 1 is drawn under heating to form a suspension part 4 having small diameter. The upper connection part 5 of the engaging part 4 is tapered downward and the lower connection part 6 is tapered upward to facilitate the alignment of the glass rod 1 in suspension to enable the vertical suspension of the rod. Since the tapered part is formed by the hot drawing, engaging parts 4 having the same form can be formed each time by keeping the heating condition and the drawing length at respective specific levels. The rod is suspended by a suspension tool 7 having the form shown in the figure and rotated.

Title: Printing control device
Inventor: KAWAGUCHI TADASHI
IPC: G06F3/12
Filed: 1991-12-04
Abstract: PURPOSE:To shorten the output waiting time at the time of printing output by preferentially processing data capable of being processed within a short time. CONSTITUTION:A printer 10 is connected to hosts 102, 103, 104. When the hosts 102, 103 send a printing command to the printer 10 almost simultaneously, the printer 10 receives the data of the first received command. When the data does not reach definite quantity, printing is started but, when the data reaches the definite quantity, the printer receives the data from the host emitting a separate printing command. When this data does not reach definite quantity, printing is immediately started but, when the data reaches the definite quantity, interrupted data is received. This operation is repeated each time when a definite quantity of data is received and, when the data does not reach definite quantity, all of the data received in the past from the host receiving the data at this point of time are subjected to printing output. As mentioned above, by dividing data by definite quantity and parallelly receiving the data with respect to all of the hosts emitting a printing command, the smallest data can be outputted first.

Abstract: PURPOSE:To enhance the crystalline quality by a method wherein, while sustaining the growing pressure in a growing chamber exceeding one atmospheric pressure, material gasses are decomposed at the position near the surface of a heated substrate so as to epitaxially grow a semiconductor layer on a substrate. CONSTITUTION:Material gasses are fed from respective cylinders 6-9 so as to show the ratio of component gasses equal to the composition ratio of a semiconductor layer to be grown. Next, the mixed material gasses are fed to a growing chamber 1 through the intermediary of a flow controller 15. Next, the flow controllers 15, 17 are adjusted to maintain the pressure in the growing chamber 1 at about 1-10kg/cm<2> preferably at about 2-5kg/cm<2>. Next, the gasses from the growing chamber 1 are exhausted to an eliminator 22 through the intermediary of a block valve 19 and the flow controller 17. At this time, sulphur and selenium are hardly eliminated from the grow up semiconductor layer due to the high pressure in the reaction chamber 1. Through these procedures, a high quality semiconductor crystal can be formed on a substrate 3.

Title: Intake duct
Inventor: KINO HITOSHI
IPC: F02M35/12
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To suppress intake noise while engines run slow and ensure a sufficient amount of intake air while they run fast both without using electronic control circuits, solenoid stop valves and the like. SOLUTION: A retainer means limits the movement of a valve 40 being forced to open a second intake passage 2 closed, and frees the valve 40 to close the second intake passage 2 opened. In forcing the closed second intake passage 2 open, the valve 40 undergoes a strong resistance that a clip 5 opplies to a tappet pin 44 and thus struggles through the action. In forcing the opened second intake passage 2 closed, on the other, the valve 40 experiences a small force that the clip 5 applies to the tappet pin 44 and thus easily swings to open the second intake passage 2.
