Title: Ink jet recording apparatus
Inventor: TSUZUKI MITSUO
IPC: B41J2/205
Filed: 1982-12-10
Abstract: PURPOSE:To keep the speed of an ink almost constant even if the droplet volume is changed to prevent recording distortion, by determining a nozzle shape and the viscosity resistances of a check valve and an ink passage so that a time required in bringing the flow speed of ink injected from a nozzle to a steady state after a voltage pulse is applied becomes shorter than the min. width of the voltage pulse. CONSTITUTION:An ink jet head is constituted of a nozzle 1, a pressure chamber 3, an ink supply port 4 and check valves 5, 6 for inhibiting the flow in the direction of the ink supply port 4. When voltage having polarity for reducing the volume of a pressure chamber 3 is applied to an electromechanical conversion element 2, the ink is injected from the nozzle 1 while passing the check valve 5. When voltage is returned to original one, the ink is sucked from an ink supply port through the check valve 6. By determining the resistance of the check valve flow passage so that time constant determined by the inertia resistance of the nozzle and the normal direction resistances of the flow passage and the check valves becomes shorter than the variable range of a driving pulse width, it is possible to change the volume of the ink droplet while keeping the speed thereof constant.

Filed: 1994-08-19
Abstract: PURPOSE: To enable fan-shaped permanent magnets to be arranged at regular intervals without using a jig, and also, prevent the diffusion and breakaway of the fan-shaped magnets by centrifugal force by forming positioning projections in the shape of expanding outward, corresponding to the number of fan-shaped permanent magnets, at the periphery of a rotor yoke. CONSTITUTION: Positioning projections 2-1 in the shape of inverted trapezoids expanding outward are made at the periphery of a rotor yoke 2, thus the danger of the diffusion and breakaway of the fan-shaped permanent magnets 1 by centrifugal force is eliminated, conjointly with the shape of the ends of the fan-shaped permanent magnets 1 abutting on here. Hereby, the fan-shaped permanent magnets 1 can be arranged at regular intervals along the rotor yoke 2 without using a jig, and a rotor which can withstand high-speed revolution without using a reinforcing member, can be made.

Title: Self-diagnosis fitting for infrared ray detector
Inventor: OCHIAI KAZUTAKA
IPC: G08B29/00
Filed: 1992-07-23
Abstract: PURPOSE:To provide a self-diagnosis function by fixing an infrared ray emitting element at a position allowing emission of infrared ray toward an infrared ray detector upon conduction. CONSTITUTION:When a pyroelectric infrared ray detector 5 performs self- diagnosis, pseudo-signals for self-diagnosis are applied between pins 4a, 4b and 4c, 4d of a self-diagnosis fitting 1 and nichrome wires 3a, 3b are conducted. Consequently, the nichrome wires 3a, 3b are heated to emit infrared rays. The infrared rays pass through an infrared ray transmissive filter 7 and reaches an infrared ray detecting section 8 where infrared rays are detected. Heating of the nichrome wires 3a, 3b simulates a state where the detector 5 detects infrared rays from a human being and allows self-diagnosis.

Title: Ion implantation
Inventor: MITANI YASUHIRO
IPC: H01L21/265
Filed: 1991-08-28
Abstract: PURPOSE:To implant impurity ions in an amorphous silicon film without reducing the resistance value of a gate insulating film by a method wherein mixed ion energy is applied from the side of the amorphous silicon formed on the upper surface of the gate insulating film. CONSTITUTION:A mixed ion beam proceeds to the direction of an ion beam irradiation object 1 and is applied to the whole surface of the object 1 in a shower form. In the mixed ion beam, an impurity ion beam in the solid body has a large slowing-down action, while a hydrogen ion beam has a small slowing-down action and the distance of the impurity ion beam to proceed in an amorphous silicon film 19 and a gate insulating film 18 is smaller than that of the hydrogen ion beam to proceed in the films 19 and 18. Accordingly, impurity ions are implanted in both regions 19a and 19c of the film 19 and hydrogen ions do not stagnate in the film 18. Thereby, it becomes possible to form a thin film transistor having the gate insulating film of a large resistance value.

Filed: 1993-09-01
Abstract: PURPOSE:To make the thermal deformation of a side weir small by fitting a base member planted with a ceramic plate sliding the end surface of a cooling roll to a water cooling type metallic case through monolithic refractory and shrinkable heat insulating material. CONSTITUTION:The base member 12 is arranged to the metallic case 10 and the shrinkable heat insulating material 22 is filled in the expanding part. The monolithic refractory 11 is poured into gap between the metallic case 10 and the member 12. Moisture in the refractory 11 is removed with a drying furnace. At this time, cooling medium is flowed into a cooling medium flowing passage 19 in a stiffening body 16 at the back surface of the metallic case to prevent the deformation of the stiffening body 16. The ceramic plate 13 is stuck to the base member 12. Before starting continuous casting, the side weir 9 is preheated with a heater 14. As the shrinkable heat insulating material 22 is filled into gap between the metallic case 10 and the base member 12, the thermal expansion at the time of drying and preheating is absorbed and the thermal deformation can be restrained.

Filed: 1992-07-24
Abstract: PURPOSE:To suppress the reduction of the lubricating oil quantity in an oil reservoir in inclination and spread the tilt allowable range by connecting each oil reservoir for storing the lubricating oil of a plurality of units through an oil levelling pipe. CONSTITUTION:When a compression unit swings and tilts rightward, the lubricating oil in a lubricating oil reservoir 5 transfers into an oil reservoir 6, passing through an oil levelling pipe 7, and at the same time, the lubricating oil in an oil reservoir 14 transfers into the oil reservoir 5, passing through an oil levelling pipe 6, and the lubricating oil in the oil reservoir 6 transfers into an oil reservoir 15 through an oil levelling pipe 17, and the oil level of the lubricating oil becomes as shown by the broken line L. Accordingly, if the diameter of the oil levelling pipe 16 is set equal or larger than the oil levelling pipe 7, the reduction of the oil quantity in the oil reservoir 5 can be prevented. When the tilt time is long, the oil quantity in the oil reservoir 5 starts to reduce, and the time up to the generation of the lubricating disorder of a compression mechanism or seizure trouble can be prolonged by properly selecting the diameter of the oil levelling pipe.
