Title: Pilot type diaphragm valve
Inventor: FUJITA KOZO
IPC: F16K47/02
Filed: 1994-08-19
Abstract: PURPOSE:To provide sufficient water hammer suppressing effect without any reduction in a diameter of an extraction hole by arranging a projection part toward a liquid feeding part side from a diaphragm and forming the projection part of a repairable elastic member. CONSTITUTION:Toward a fluid feeding part 30, a projection part 51 is arranged in the circumference part of a diaphragm 10, and a back pressure chamber 32 and the liquid feeding part 30 are communicated with each other via a liquid feeding side passage 20 penetrating the diaphragm 10 and the projection part 51. The projection part 51 is formed of an elastic member having restorability such as rubber, and a shape of a cross section of the liquid feeding side passage 20 formed in the projection part 51 is easily deformed by a pressure difference between the liquid feeding part 30 and the back pressure chamber 32. According to the close of a diaphragm valve element 50, a pressure difference between the fluid feeding part 30 and the back pressure chamber 32 is increased, and a pressure of the fluid feeding part 30 at high pressure works on the outer circumferential face of the projection part 51, and consequently, the projection part 51 is deformed. Then, a cross sectional area of the fluid feeding side passage 20 is reduced, a flow rate of the fluid flowing into the back pressure chamber 32 from the fluid feeding part 30 is reduced, closing valve action of the diaphragm valve A is slowed, and consequently, water hammer can be suppressed.

Title: Non-magnetic one-component color toner
Inventor: YUKITAKE KAZUNORI
IPC: G03G9/09
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a non-magnetic one-component color toner hardly causing defects such as rising of image density and collapse of thin lines by establishing a specified relation among the average particle size W (unit: μm) in the weight distribution, the average particle size N (unit: μm) in the number distribution and the distribution ratio (a) (unit: %) in the particle size range to which N belongs. SOLUTION: The toner to be used is managed by the particle size range by measuring the toner particle distribution so that the relational expression: (N×a)/W>=30 (%) is satisfied among W, N and (a) in the particle size range to which N belongs. Since this toner has little in fluctuation of the average particle size, the electrification amount is stable, a toner selection phenomenon can be restrained and an initial-stage defective image having fogging, defective cleaning, etc., is hardly caused. The defects such as the rising of image density and the collapse of thin lines can be eliminated even at the life test of continuous printing. This non-magnetic one-component color toner is composed of a binder resin such as a polyester resin, an electrification control agent such as an dyestuff of an iron-azo compound complex, a coloring agent such as a dis-azo pigment and an additive.

Title: Method for controlling copying machine
Inventor: MIYAWAKI SHOZO
IPC: G03G13/00
Filed: 1985-09-07
Abstract: PURPOSE:To shorten the time required for making copying operations when the surface and back of an original are copied, by eliminating wasteful times during periods from the comple tion of surface copying to the start of back copying and from the completion of the surface copying to the time when copies are contained in an intermediate tray. CONSTITUTION:Two examples of copying operations are considered with a copying machine which is set to the both-side mode and recycle mode and has an intermediate tray having a containing capacity of fifty sheets, as follows. In the case of Example 1, the numbers of originals and copies to be taken are three and ten, respectively, and, in the case of Example 2, the numbers are twenty and five, respectively. When the copying operation of Example 1 is carried out, the surface sides and backsides of the three originals are continuously copied for ten sets at every set and the copies are contained in the intermediate tray 133, but, when the copying operation is made in this way, a copying operation inhibiting time which is required in conventional examples becomes unnecessary. In the same of Example 2, if surface copying is carried out at once on the twenty originals, the number of copies becomes 20X5=100 which cannot be contained in the tray 133. Therefore, by formula [(LXM)+N=the number of copies per set, where L=2 sets, M=2 times, N=1 set, each one of surface copy is taken from the originals and this one-copy operation is repeated twice and, after the copies are contained in the tray 133, back copying operations are carried out. After repeating the above-mentioned copying operations twice, the twenty originals are copied one each for the surface and back, and thus, copies of five sets each are completed.

IPC: B60G17/015
Filed: 1985-09-06
Abstract: PURPOSE:To simplify a device by extracting an output corresponding to a frequency band which is not most sensitive enough against a damping force of a shock absorber, out of road surface information inputted through suspension devices. CONSTITUTION:Road surface information DS detected by a vertical acceleration sensor 1 is inputted into band bus filters 7 and 8 of a signal processing circuit 6. As No.1 band bus filter 7 has a resonance point around 12 to 13Hz. a frequency band around a spring lower resonance frequency is allowed to pass through, and similarly No.2 band bus filter 8 allows a frequency band around a resonance point 1.5Hz of a spring upper resonance frequency to pass through. And each of these frequency components which have passed through, is sent to No.1 and No.2 processing units 9a, and 9b of a road surface identification circuit 9 for rectifying and smoothing 10 through 13 so as to output road identification signal DC1 through DC2. This configuration can simplify a device.

Title: Station tuning device for television receiver
Inventor: MATSUURA MORIAKI
IPC: H03J7/02
Filed: 1989-07-28
Abstract: PURPOSE:To follow up any change with the lapse of time by increasing or decreasing the second data so as to output the tuning voltage, with which a station selecting frequency holds an optimum tuning point, corresponding to a change in the height of a high frequency automatic frequency control (AFC) voltage and rewriting a volatile memory. CONSTITUTION:On a RAM 7 as the volatile memory in a microcomputer 1, the displacement data (BT displacement data) of tuning voltage data are stored for each channel. The microcomputer 1 normally monitors the automatic frequency control (AFC) voltage and compares the AFC voltage with a midpoint potential. For example, when the AFC voltage is higher than the midpoint potential, the BT displacement data stored onto the RAM 7 in the microcomputer 1 are incremented. As a result, BT data + BT displacement data are outputted as the tuning voltage to a tuner 5 until the absolute value of the BT displacement data becomes a certain fixed value. This tuning voltage is a voltage corresponding to the local frequency for the optimum tuning point.
