Title: Ink jet head
Inventor: ABE TOMOAKI
IPC: B41J2/045
Filed: 1989-04-26
Abstract: PURPOSE:To make gaps between pressure generating members smaller so as to increase the density of dots of printed characters by causing a plurality of pressure generating members to share one hole as a nozzle. CONSTITUTION:When impressed voltage 16 is applied selectively to pressure generating members 13, a member 13 which has been selected moves in a direc tion of an arrow 22 and applies pressure to ink, causing the ink in a nozzle 14 under the member 13 to be delivered from the nozzle 14 in the form of ink droplets 20. Since the nozzle 14 has a slit-like shape passing through a nozzle formation based plates 15 and a plurality of pressure generating members 13 are disposed along the slit-shaped nozzle 14, the gap (d) between the members 13 can be made smaller regardless of the shape of the nozzle 14. When the width (b) of the member 13 is 250 mum, the gap (d) can be made about 300 mum and hence the density of dot of printed character becomes 80 dpi. As a result, density is improved, as compared to the conventional 60 dpi, by about 30%.

Title: Mass spectrometer
Inventor: SHIZUKUISHI KENICHI
IPC: G01N27/62
Filed: 1986-05-09
Abstract: PURPOSE:To enable even a mass number of a great-mass sample to be measured with high resolution, by impressing an electric field on ion beams, for correcting deviation of a theoretical orbit from a real one in the ion beams incident to a magnetic field and synchronizing with a sweep current in the magnetic field. CONSTITUTION:Ion beams 3 having speeds focused by an electric field 2 are directionally focused in a magnetic field 4, and being classed every mass in their ions, so as to be incident to a collector 6. Because the amount of a magnetic field leaking due to the magnetic field 4 sweep becomes large in conformity with enlargement of the magnetic field current, the ion orbit, synchronizing with the magnetic field sweep, is also bent inside against the theoretical orbit. Voltage synchronizing with the magnetic field sweep is impressed on a deflector 8 by the use of a deflector power source 9. Therefore, the ion orbit bent by the leaking magnetic field is returned to the theoretical one by the electric field of the deflector 8.

Title: Production of long sized magnetic scale
Inventor: OOKUBO HIROYUKI
IPC: G01B7/02
Filed: 1981-07-08
Abstract: PURPOSE:To obviate the disturbance in the sequence that magnetized parts of different polarities appear alternately in the longitudinal direction even in the joint parts with the magnetic scale of the next one unit length and to maintain the accurate inter-scale spacings even in the joints between the magnetic scales of each one unit length with simple work. CONSTITUTION:Long-sized ribbon-like magnetic recording media 51 are disposed in such a way that their respective one ends are arranged evenly with respect to a magnetizer 60. When electric current is supplied to a coil 63, the media 51 are vertically magnetized in the positions corresponding to projecting parts 62 and 2n pieces of magnetized parts 53 differing in polarities alternately are formed in the longitudinal direction, whereby the magnetic scale of one unit length is magnetized. The magnetized parts 53a, 53b at both ends of said unit length are mutually reversed in the magnetization directions. While the relative positions of the magnetizer 60 and DMEs 56, 57 are held maintained, the long- sized media 51 formed with the magnetic scale by one unit length are fed approximately by one unit length in an arrow A direction and the unmagnetized  parts of the media 51 are positioned on the magnetizer 60 so as to be formed with the magnetic scale of the next one unit length.

Title: Recording disk
Inventor: KITAGAMI OSAMU
IPC: G11B23/00
Filed: 1989-04-26
Abstract: PURPOSE:To hold satisfactory flatness for a long time by providing the ring- shaped projection of an elastic body such as rubber in inner and outer circumferential parts on the surface of a disk substrate, adhering and fixing a recorded film on the upper surface of this projection. CONSTITUTION:In the inner and outer circumferential parts on the surface of a disk substrate 2, a continuous ring-shaped projection 3 of the elastic rubber is installed and a recording film 4 is adhered and fixed on the upper surface of this projection 3. Accordingly, distortion caused by the shrinkage of the recording film 4 is compensated by the elastic deformation of the ring-shaped projection 3. It is effective for uniformly loading tension to the recorded film and for manufacturing a medium that the thickness of the ring-shaped projection 3 is set in the range of 0.5-5mm and width in a radial direction is set in the range of 1-20mm. Thus, the fixed recording film 4 is stably extended in the radial direction of the disk and even when a slight change with the passage of time is generated in the dimension of the recording film 4, the recording film is stably held by the elasticity of the ring-shaped projection 3. Then, a flat recording surface can be realized for a long time without generating loose ness or distortion on the recording surface.

IPC: F02M1/04
Filed: 1982-06-21
Abstract: PURPOSE:To perform accurate air-fuel ratio control for the stable operation of an engine through a simple construction, by using a single thermosensitive mechanism to regulate a throttle valve and fuel. CONSTITUTION:When the temperature of an engine is low, the operating rod 19 of a thermosensitive mechanism 4 is moved back and an arm 22b is pushed on a restricting arm 24 by the elastic force of a cam return spring 35 to keep the degree of opening of a throttle valve 2 high. When the temperature of the engine is high, a fluid M is expanded to push out the operating rod 19 to turn a cam 22 clockwise to lower the degree of opening of the throttle valve 2 through the restricting arm 24 which follows the arm 22b. At the same time, a link 36 coupled to the cam 22 comes into contact with a lever 31 on the rear end of a valve stem 33 and moves rightward with the turning of the cam to displace a valve element 12 forth. When the negative pressure in an intake pipe has exceeded a prescribed magnitude as a result of the complete combustion of the engine, a diaphragm 26 is sucked against the elastic force of a spring 27 to turn the lever 31 clockwise to move the valve element 12 forth so that a fuel passage 6 is closed.

Title: Polishing and grinding having damping properties and device for cutting work
Inventor: TOYOKURA YASUSHI
IPC: B24B55/04
Filed: 1995-04-06
Abstract: PURPOSE: To restrain adhered layers from being formed out of splashed powder into the inner surface of a grinding wheel cover by forming a flame sprayed layer made of a tungsten carbide group sintered hard alloy the thickness of which is equivalent to specified Z thickness of the grinding wheel cover made of a steel plate at least in the inner surface of the grinding wheel cover made of a steel plate. CONSTITUTION: A grinding wheel cover 4 made of a steel plate is formed out of a carbon steel plate as thin as roughly 1mm, and a flame sprayed layer is formed in the inner surface of the aforesaid cover by the use of tungsten carbide group sintered hard alloy powder. The thickness of the flame sprayed layer is set at 10 to 30% thickness of the grinding wheel cover 4. The aforesaid flame sprayed layer can be formed by plasma spray coating using tungsten carbide group sintered hard alloy powder. In this case, no desired damping properties can be obtained if the thickness of the flame sprayed layer is less than 10%, and time for plasma spray coating is lengthened, and the grinding wheel cover 4 is changed in quality if the thickness exceeds 30%.  Thus as mentioned above, damping properties can thereby be enhanced, and the grinding wheel can thereby be made larger in size and higher in output power.

IPC: F02B39/00
Filed: 1981-07-10
Abstract: PURPOSE:To raise the supercharging pressure at the time of low-speed operation of the engine and enhance response characteristic at the time of acceleration, by a method wherein an external periphery side wall surface at a starting part of winding of a scroll inlet of a turbine casing is partially made to be a movable wall capable of moving in the radial direction. CONSTITUTION:The movable wall 18 capable of rotating with a shaft 20 as a center is provided at a part of the external periphery side wall at the starting part of winding of the inlet of a turbine scroll 10. At the time of low-speed operation of the engine, when an electric current is passed through an electromagnet of an actuator 23, an arm 21 is attracted rightwards and the movable wall 18 is moved around the shaft 20 to come to position B. As a result, the cross-sectional srea of a passage 19 is reduced, so that the pressure and flow velocity at the inlet to turbine rotor 14 are increased, then turbine torque is increased, and the rotation number of the rotor 14 is increased. Consequently, the compressor output pressure is increased, the output of the engine can be increased and the torque characteristic of the engine is enhanced.

Abstract: PURPOSE:To maintain line feed accuracy at high standard, without requiring special consideration on dimensional accuracy or fixing accuracy of respective parts, by making tractor drive control so that the positions of a line to be printed through a print head and a guide hole of a paper are matched in a predetermined period. CONSTITUTION:When a non-specific position (e) of paper 5 is at a detecting position (f) of a sensor 7, a switch 4a is operated to clear detecting condition of the sensor 7. The sensor 7 detects a guide hole 5a of the paper 5 at a position (h) which is ahead of the position (e) by a distance (g). When first printing is made at a position which is ahead of the position (h) by a distance (i), the distance (i) is stored in a memory in a central control section 11. Although the line feed pitch (j) varies according to setting conditions prior to start of printing, the pitch (b) of the guide holes 5a is always constant, and thereby appearing times of the guide holes 5a within a distance (k) are specified by a switch 4b so as to correct the distance (l) (m) to be equal to the distance (i). In other word, line feed correction is made by the central control section 11 corresponding to a detection signal of guide hole fed from the sensor 7 and a specification signal fed from a switch panel 4.
