Title: Ultraviolet image forming optical system
Inventor: MARUYAMA KOICHI
IPC: H01L21/027
Filed: 1994-12-22
Abstract: PURPOSE: To easily execute the adjustment of measurement and the check of performance by dividing a system into a collimator lens and an image forming lens and providing an optical branching system at the part of parallel luminous flux between both lenses. CONSTITUTION: This system is provided with two lenses of the collimator lens 11 and the image forming lens 12. By the lens 11, light diverging from one point on a reticle(chart for reduction and exposure) 13 is changed into the parallel luminous flux. On the other hand, the image of the reticle 13 is reduced and projected on a wafer(photosensitive material) 14 by the lens 12 receiving the parallel luminous flux. Then, the luminous flux is parallel between the lenses 11 and 12. Since two lenses are separated at a part where the luminous flux is parallel, magnification is not changed even when a focusing action is executed by moving only the lens 12.  Then, the parallel luminous flux emitted from the lens 11 and the light reflected on the wafer 14 and transmitted through the lens 12 again are guided to an external observation system by an almost parallel beat plate 15 constituting an interferometer. Besides, assembling work can be adjusted while the aberration state of the lens 12 is observed.

Title: Ink jet recording head, ink jet recorder, and information processor
Inventor: SUZUKI TAKUMI
IPC: B41J2/165
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To wipe off unnecessary ink so that the part from a jet face to a jet port is not stained by providing a basic unit structure comprising a pair of protrusions for isolating ink on the opposite sides of a row of a plurality of jet ports closely thereto on the ink jet face. SOLUTION: A nozzle pattern member is arranged on the substrate of a recording head and two protrusions 3 for isolating ink are provided on the opposite sides of a plurality of ink jet ports 10 arranged in a row in parallel with the row. When the ink jet face is wiped off, a wiping blade 4 is moved in the direction shown by an arrow A along the row of ink jet ports and the ink 5 is moved along the protrusions 3. Even if the ink tries to exceed over the protrusions 3, it is blocked by blade 4 and the protrusions 3. Since the protrusions 3 are provided, the part where the nozzle pattern member is not arranged can also be sealed resulting in the enhancement of electric insulation and reliability.

Title: Optical device for copying machine
Inventor: MATSUI HIDEAKI
IPC: G03G15/041
Filed: 1989-12-13
Abstract: PURPOSE:To shorten a control time in the case of variable magnification copying by moving 1st and 2nd carriages at specified speeds respectively and fixing an image-formation lens and displacing the arrangement of 2nd and 3rd carriages in the case of switching from unmagnification copying to variable magnification copying such as magnifying or reducing copying. CONSTITUTION:The 1st carriage 4 and the 2nd carriage 7 perform scanning toward a returning position in a scanning distance (x) in the speed ratio of 1:1/2 by a scanner motor. In the case of switching to the variable magnification copying for obtaining magnifying or reducing copying, the lens 8 is not moved but the 2nd carriage 7 and the 3rd carriage 11 are displaced by a motor for variable magnification. Thereafter, the 1st carriage 4 and the 2nd carriage 7 are made to scan in the specified speed ratio by the scanning motor. Thus, the moving quantity of the carriage which moves at the time of switching the variable magnification becomes a half in a conventional lens, thereby drastically shortening the control time in the case of variable magnification copying.

Title: Applying mehtod for soldering paste
Inventor: SAKOJIRI HIROMICHI
IPC: B23K3/06
Filed: 1990-11-26
Abstract: PURPOSE:To avoid viscosity increase of the soldering paste by chemical reaction and to apply the soldering paste with high accuracy by supplying solder powder and an active assistant from separate applicators. CONSTITUTION:One applicator is filled up with the solder powder 1, rosin and an organic solvent 2 and the other applicator is filled up with the active assistant 3, rosin and the organic solvent 2. In this way, since the solder powder is separated from the active assistant, these are not subjected to chemical reaction each other and the soldering paste always keeps constant viscosity and the soldering paste can be applied to a printed board 6 with high accuracy. In recent years, with miniaturization of electronic equipment, requirement for high density mounting increases and accordingly, it is useful to be able to apply the soldering paste to the printed board with high accuracy.

Abstract: PURPOSE: To prevent light beams from being intensively cast to a part of a photosensitive body, by stopping driving of a laser driver, a scanner motor and indicating that an error occurs when light beams are not detected by a BD detector within a fixed time after the scanner motor starts driving. CONSTITUTION: When a print instruction is generated, the rotation of a scanner motor 506 is started and a timer is set.

Abstract: PURPOSE:To stably suck the floating matter on a liq. surface with high efficiency by providing an adjustable-speed cylinder device and appropriately maintaining the relative position between the suction port of a float and the liq. surface regardless of the variations in the height of the liq. surface. CONSTITUTION:The adjustable-speed cylinder device 10 consists of a cylinder device 11 and a speed setting part 21. The cylinder device 11 is formed by a cylinder 12, a piston 13 for insulating the upper chamber 14 from the lower chamber 15, and a piston rod 16 with a float 5 attached to its lower end. The speed setting part 21 consists of a check valve 22 communicating with the upper chamber 14, a first throttle valve 23, a check valve 24 communicating with the lower chamber 15, and a second throttle valve 25. The second throttle valve 25 is narrowly throttled to the extent that the float 5 follows a rapid lowering of the liq. surface, and the first throttle valve 23 is widely throttled so that the float 5 follows a slow rise of the liq. surface. By this method, the jumping of the float into the atmosphere due to the dynamic inertia of the float 5 after the fast lowering of the liq. surface or after the slow rise of the liq. surface is prevented, and the succeeding sinking of the float 5 into the liq. is also obviated.

Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To rapidly and positively discriminate the rotary direction of a rotary shaft by judging the forward/reverse rotation state of a pump rotary shaft according to the phase difference signal and the speed signal of two rotary signals. SOLUTION: Non-contact displacement meters 2a and 2b arranged while being separated by 90 degrees in the peripheral direction of a rotary shaft 30 output a shaft vibration wave signal including one pulse per rotation by a cut-out part 30a being provided on the outer-periphery surface of the rotary shaft 30. Pulse generators 3a and 3b extract a pulse from the waveform signal and output pulse signals Fa and Fb to a phase meter and a speed meter 5. Then, rotation state judging equipment 6 inputs a phase (difference) signal P of both pulse signals Fa and Fb being outputted from the phase meter and a speed signal N being detected by the speed meter 5 and judges that the rotary shaft 30 is rotating forward (reverse) when the speed signal N ranges from 30 rpm to a reference speed.  Also, when the speed signal N ranges from 0 to 30 rpm, it is judged that the rotary shaft 30 has stopped regardless of the value of the phase signal P.
