Title: Power steering device
Inventor: KOMATSU KOICHI
IPC: B62D5/24
Filed: 1984-11-02
Abstract: PURPOSE:To make steering wheel load variable so smoothly according to a car speed, by controlling movement of a spool valve of a control mechanism with a hydraulic reaction mechanism which operates with differential pressure between a fixed throttle and a variable throttle mechanism installed in the point midway in a bypass passage. CONSTITUTION:In time of driving at low speed, this slow running is detected by a sensor 53, operating a solenoid 51a with a signal, and a throttle of a variable throttle valve is enlarged, increasing the discharge of a hydraulic fluid to some extent. There fore, differential pressure between the variable throttle valve and a fixed throttle mechanism 50 is made smaller whereby pressure of the hydraulic fluid led into reaction chambers 31 and 32 from a branch passage 52 is also made smaller. Here, when a stub shaft 29 is rotated with a steering wheel 43, at first a sector shaft receives resis tance of wheels, and a piston 1 and a worm shaft 8 both are immovable whereby there is produced relative turning displacement between these shafts 8 and 29. Accord ingly, when a pin 30b is turned round, either of pistons 23 and 24 moves to the right or left so that a shaft 20 rotates and a spool valve 12 is slidingly moved by a pin 30a, whereby the hydraulic fluid is selectively fed or drained to or from each of operat ing chambers 3 and 4 so that steerage is assisted and a steering wheel is nimbly steera ble.

Title: Power amplifier
Inventor: FUKUDA EISUKE
IPC: H03F3/20
Filed: 1989-09-07
Abstract: PURPOSE:To improve the exactness of the operation of an LINC(Linear amplifier with Nonlinear Component) system power amplifier by controlling a constant envelope signal level so that two constant envelope signals are placed on a same circle independently of aging or temperature change. CONSTITUTION:When a level of a constant envelope signal A is increased and the relation of A>B exists, a phase difference  theta between a vector synthesis signal X and a vector difference signal Y is smaller than 90 deg., since an output Vd of an operation amplifier 16 is zero, the decrease of the level of the signal A is stopped. Conversely, when the level of the signal A is decreased and the relation of A<B exists, since the phase difference  theta between the signal X and the signal Y is larger than 90 deg., the output Vd of the operation amplifier 16 is larger and the level of the signal A is increased. Since the level of the signals A, B is controlled to be identical at all times, the LINC system power amplifier is operated exactly.

Title: Display device in finder
Inventor: MUKAI HIROSHI
IPC: G03B17/20
Filed: 1988-09-16
Abstract: PURPOSE:To improve contrast and the brightness of a screen by using guest and host liquid crystal in which liquid crystal in a cholesteric and nematic phase transition type which has negative dielectric anisotrophy is set as a host and two-color pigment with absorption anisotrophy is set as a guest and performing orientation processing so that the orientation factor of the liquid crystal may become perpendicular to an electrode surface when a voltage is off. CONSTITUTION:The cholesteric and nematic phase transition type liquid crystal F having the negative dielectric anisotrophy becomes a cholesteric phase in which the direction factors of a display part are helically oriented around an axis perpendicular to an electrode E surface when a power source is on. Besides to that, by using the two-color pigment G having the light absorption anisotrophy as the guest, the direction factors of the two-color pigment G become the member of helical structure when the liquid crystal becomes the cholesteric phase, so that all the pigments are oriented in all the directions on a plane parallel with the electrode E surface and light shielding rate is improved. The transparency at the time when the voltage is off can be improved by making orientation degree in a direction where the two-color pigment G does not absorb light advancing in a direction perpendicular to the electrode E higher. Thus, display in a finder where the contrast of the display part is high can be accomplished.

Abstract: PROBLEM TO BE SOLVED: To provide a uniform and reproductive vacuum micro element with a gate conductive layer electrically insulated and arranged around a quantum size of thin terminal in such a manner that the short small diameter of the opening of an emitter is equal to or less than a shortest distance between emitter and gate metals. SOLUTION: A Si substrate 1 with n-type impurities doped at a high concentration is thermally oxidized to form a thermally oxidized film 2 of thickness 1.5μm, e.g. on the surface. Then, a 0.2μm thick MO as a gate conductive layer 3 is spattered all over and a 1.0μm thick SiN film 4 is laminated thereon with CVD. An array-patterned photoresist mask with an 2μm diameter of circular opening is formed and laminated films are etched in sequence by using PIE, antimony fluoride etching to expose the Si surface. This is anode-formed in hydrofluoric acid to make the surface porous. Only the shape of the end of an emitter is sharpened so that an obtained element has no leak current to a gate at 1μA per unit opening when 200V voltage is applied to an anode.
