Title: Powder molding device
Inventor: MIZUTANI IWAO
IPC: B22F3/03
Filed: 1980-12-27
Abstract: PURPOSE: To make constitution simple and make transverse space as small as possible by incorporating the constitution approximate to ordinary die sets which do not perform powder transfer in a withdrawal type powder molding device.  
     CONSTITUTION: Powder 19 is packed in a floating die 9 (stage A), and male dies 23, 27 are lowered until an inner punch 27 abuts on the powder 19 (stage B). When the male dies descend further, an inner punch 14 is forced by the powder and the powder is slightly compressed to receive transfer effect so that it is shifted into the die 9 (stage D). Next, an actuator 10 forces the punch 14 upward and the punch 27 retreats against an outer punch 23 until the punch 23 abuts on the powder, then the punches 23, 27 descend integrally, thereby compressing the powder 19 (stage D). During this time, the outr punch 17 forces rubber 16 downward and abuts on the top surface of a base plate 3. Next, the descending of the male dies is stopped, and the die 9 is lowered (stage E), and when the male dies are moved upward after said stoppage, a product 28 is removed by the punch 17 which is moved upward by the elastic force of the rubber 16.

Filed: 1990-07-16
Abstract: PURPOSE:To enable oscillation to meet a condition and symptoms of a user by moving a power shaft alone vertically and horizontally to allow the altering of an angle of oscillation stroke and an angle of initial oscillation even during the use of the apparatus. CONSTITUTION:A sliding element 21 makes a rotary motion while a guide plate 20 makes an oscillating motion centered on an oscillating shaft 3 being guided with a guide groove 20a. When a vertically moving frame 24 is pulled up using a handle 7, a motor 30 and a power shaft 31 fixed thereon 30, a disc 22 and the sliding element 21 are pulled up together. As a result, the sliding element 21 is guided to an upper part of the guide groove 20a cut in the guide plate 2n to enlarge an angle of oscillating stroke of the guide plate 20. Likewise, when a horizontally moving frame 23 is moved to the left by a handle 6, with the power shaft 31 and the sliding element 21 shifting the center of rotation thereof to the left, the oscillating motion of the guide plate 20 is biased to the left. Thus, the oscillating motion of the foot frame 1 is also made centered on a position shifted upward accordingly.

Title: Ink jet printer
Inventor: KOIDE YOSHIO
IPC: B41J2/115
Filed: 1988-07-27
Abstract: PURPOSE:To control printing accurately by a method wherein a charged quantity of an ink particle is detected based on an electric signal electrically induced with a deflecting electrode by pass of the ink particle under a state in which a reverse polarized charge to that in printing is applied to the ink particle. CONSTITUTION:When a period for detection of a charged quantity comes, a phase control circuit 38 detects a charged quantity of an ink particle at each angle changing a phase of a charged pulse 22 to a making particle signal 16 by each specific angle. A charged ink particle at that time should not stick to paper to be printed by receiving deflection. Therefore, a polarity of the charged pulse 22 is reversed to make a polarity of charge to be charged to the ink particle reversed to that in printing, and is deflected to an opposite side of the paper to be printed. Positive and negative pulses are respectively generated at the start of passing and at the end of a charged ink particle group by the charged pulse of each phase. Thereby, a phase when a pulse of a highest amplitude among charged quantity detection waveform appear, is an optimum phase of the charged pulse. By establishing the phase of the charged pulse 22 to this optimum phase, ink is charged instantaneously when it is made into particles, and printing can be accurately controlled.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a conversion panel that is excellent in luminance and sharpness by allowing a stimulable phosphors expressed in a specific formula on a support to contain BaF2 of a set % or lower, and coating with a protective layer. SOLUTION: The quantity of BaF2 contained in stimulable phosphors expressed in a formula is set at nor more than about 10%, preferably about 1 to 10%, (in the formula, represents one selected from such atoms as iodine, bromine and chlorine). The luminance and sharpness of the stimulable phosphors degrade if the content of BaF2 is 10% or more, and the sharpness of them lowers if it is not more than about 1%. Moreover, X/Ba<=0.975 is established for the stimulable phosphors, and the value of X/Ba is a value measured with an ICP-MS by extracting the stimulable phosphors with nitric acid. In the case of X/Ba>0.975, the stability and resistance to humidity deteriorate. If the crystal structure of the stimulable phosphors is spherical or polyhedral, the filling percentage, sensitivity and resolution are improved.  Furthermore, the particle diameters of the stimulable phosphors are set at about 0.1-10 μm.

Filed: 1980-12-26
Abstract: PURPOSE:To increase the number of targets to a tracking radar device using an electronic scan antenna having the simultaneous target processing capacity, by giving the time sharing to the same pulse repetitive frequency by means of a gate signal generator. CONSTITUTION:A gate signal generator 8a gives the time sharing to the same pulse repetitive frequency and generates a gate signal in order to control many targets within the pulse repetitive frequency of a radar. This gate signal is applied to a beam direction controller 4, a transmitter 1a, a receiver 5, a distance measuring device 6a and an angle measuring device 7a respectively. Thus plural target specifications are obtained within the same pulse repetitive frequency. With the generation of such gate signal, a transmission pulse is produced for each target to avoid the overlap of the reception and arrival of the echo which is reflected from each target. As a result, the number of targets can be increased to a tracking radar device.
