Title: Flat linear pulse motor
Inventor: AZUMA HIROSHI
IPC: H02K41/03
Filed: 1986-10-21
Abstract: PURPOSE:To make a motor lightweight and thin-shaped, by magnetically composing the flux paths of permanent magnets and exciting coils so that the flux may go through a moving piece. CONSTITUTION:A flat-plate-shaped linear pulse motor is arranged on a base 10 and composed of a stator 1 having pole tooth lines 11a-11d to make a pair in the upper and lower parts, a flat-plate-shaped moving piece 2 forming pole teeth 21 with a predetermined pitch on the upper and lower surfaces opposite to the stator 1 and a bearing mechanism 3 inserted between the stator 1 and the moving piece 2. This stator 1 is arranged with a flat-plate-shaped pole tooth member 11 at both ends of the base 10, in the centre of which flat- plate-shaped pole tooth members 15-18 are arranged through exciting coils 12 and 12b and sector-plate-shaped permanent magnets 13 and 14 and are integrally secured. Since the flux paths of permanent magnets 13 and 14 and exciting coils 12 and 12a go through the moving piece 2 accordingly, the dimension in the direct on of thinness of the moving piece 2 has no influence. The moving piece 2 can thereby be made thinner and lighter to improve the vibration and impact characteristics.

Title: Hetero-junction field-effect transistor
Inventor: SAWADA MINORU
IPC: H01L29/778
Filed: 1990-09-19
Abstract: PURPOSE:To inhibit the generation of dislocation and the scattering of an alloy, and to increase carrier mobility and sheet carrier concentration by using a semiconductor layer having narrow forbidden band width inserted into a channel layer as a superlattice layer. CONSTITUTION:An undoped GaAs layer 12 as a buffer layer, an InxGa1-xAs layer 14 as a channel layer, a semiconductor superlattice layer 16 inserted into the channel layer, an InxGa1-xAs layer 13 as the channel layer, an undoped AlGaAs layer 6 as a spacer layer, an Si-doped n-AlGaAs layer 5 as an electron supply layer, and an Si-doped n-GaAs layer 4 as a cap layer are formed in a multilayer structure on a substrate 10 in the order. The superlattice semiconductor layer 16 inserted into the channel layer relaxes distortion due to lattice mismatching with other sections in the channel layer or the substrate. Accordingly, the generation of dislocation, etc., by distortion with lattice mismatching is inhibited, thus increasing the mobility of carriers.

Title: Cantilever-type probe, scanning-type tunnel microspectrometer equipped with aforesaid probe, and data processing apparatus
Inventor: SHINJO KATSUHIKO
IPC: H01J37/28
Filed: 1990-09-19
Abstract: PURPOSE:To detect tunnel current precisely by placing a drawing out electrode, and driving electrodes at the positions not to cause layered-type electric capacity which interferes input and output of data by a probe. CONSTITUTION:In this apparatus, a drawing out electrode 2 and driving electrodes are so set as to have the lapping surface area of the drawing out electrode 2 in the thickness direction of a cantilever-like displacement device and the driving electrodes 5-10 is at most 20% of the total surface area of the drawing out electrode. In this case, driving electrodes 7-8 do not exit in the lower part (in z-axis direction) of the probe drawing out electrode 2 and electric capacity between the electrodes 2 and 7, or 2 and 8 is extremely low. As a matter of fact, when the electric capacity between the probe drawing out electrode 2 and the electrodes 5-10 was measured, it was <=0.1pF, which is the limit of the measuring instrument. Also, when a piezoelectric body of the cantilever-type probe was driven at + or -5V and f = 100-1,000Hz, the a.c. current induced in the probe drawing out electrode 2 was <=5pA. For reference, a cantilever-type probe made of the same materials, having the same size as that of this invention, and in which the driving electrodes 7-8 shown as the figure 2 not divided, was prepared and when the same evaluation as the experiment in this invention was carried out, the electric capacity was about 1pF and the induced electric current was about 5nA.

Title: Developing device
Inventor: SAKAMI YUJI
IPC: G03G15/09
Filed: 1987-10-07
Abstract: PURPOSE:To secure the degree of freedom for the scattering of toner particles in a development area and to prevent a decrease in concentration by allowing the toner particles to receive attractive force against contacting pressure to magnetic particles. CONSTITUTION:When development is carried out under such conditions that the potential of an electrostatic latent image on an image carrier is, for example, 200-600V, the gap of the development area 5 is 300mum, and the development speed is 270mm/sec, a developer 4 whose layer thickness is uniformed by a leveling member 9 is excited with a bias voltage 11 applied to the leveling member 9. This bias voltage 11 is a DC voltage having the opposite polarity from toner particles, so the degree of freedom of the toner particles is secured because of the attractive force operating against the contact pressure to the magnetic particles which is received from the leveling member 9. The toner particles are therefore scattered actively without decreasing in its flowability, so the concentration in the development area 5 is prevented from decreasing.

Abstract: PURPOSE:To obtain stable tensile forces free of restoring phenomenon of developed attitude by a method in when the developing of resistance plates is ended, a hinge formed on the lower part of an inversed U-shaped support lever is positioned at the same level as the hinge of the resistance plate. CONSTITUTION:An anchor for branch line is inserted into and set in a hole 12, and the tip of a driving pipe is coupled with a notch for receiving a driving tool and a striking force is applied. Both resistance plates 2 are developed at an expanded lead angle (alpha) and penetrated into the ground and a hook metal 10 provided on the upper end of an auxiliary support lever 7 is coupled with the upper side of the hook plate 8 of the lever 7.

Abstract: PURPOSE:To obtain excellent starting acceleration and fuel economy by adjusting the blade angle of adjustable stator blades. CONSTITUTION:When a vehicle is started, electric current to a solenoid valve 40 is cut. In consequence, the valve element 42 of the solenoid valve 40 is put in closed valve position, and line oil pressure is applied to the control port 33 of a stator blade angle control valve 30 to put the spool valve 32 thereof in lower position so that a port 31 is connected to a drain port 36, and line oil pressure in an oil pressure chamber 17 is released to put a servo piston 16 in the lefthand position, so that each of stator blades 14 is positioned in high angle position. Further, the vehicle speed V detected by a vehicle speed sensor 52 is judged, and, if it is in a normal running speed, electric current is started to be sent. Thus, the valve element 42 of the solenoid valve 40 opens to release the oil pressure in the control port 33 of the stator blade angle control valve 30, and the stator blades 14 are positioned in low blade angle position.
