Title: Guiding of guided flying body
Inventor: KIKUTA MASUMI
IPC: F41G7/22
Filed: 1988-02-09
Abstract: PURPOSE:To make it possible to guide a guided flying body to a target by a semiactive homing system by installing a radar equipment on ground behind a mountain when there is a mountain which obstructs the radio waves of a radar on the ground and installing a command receiver on a guided flying body and switching a frequency which can be received by the guided flying body by the instructions from the radar on the ground. CONSTITUTION:A main radar 1 can not detect a target 3 because it is behind a mountain 4, but an auxiliary radar 2 can detect it, and the information on the target obtained by the auxiliary radar 2 is sent to the main radar 1. The main radar 1 carries out the calculation of shooting and shoots a guided flying body 5. Until the guided flying body 5 goes over the mountain, it is guided by the command signal 7 that is given from the main radar 1. When the guided flying body 5 is over the mountain 4, the body 5 receives a standard signal 8 from the auxiliary radar 2 and at the same time the radio waves are shot from the auxiliary radar 2 to the target 3, and the reflection signal 9 reflected from the target is received. The guided flying body 5 receives both standard signal 8 and reflection signal 9 from the target and starts semiactive homing and it is continued until it hits the target 3.

Title: Projector
Inventor: NAKAMURA JUNPEI
IPC: G02F1/13357
Filed: 1986-02-10
Abstract: PURPOSE:To obtain a video sharply improved at its contrast with a simple constitution by including a liquid crystal plate around an optical axis from its vertical plane in the direction of a visual angle with maximum contrast. CONSTITUTION:Light beams radiated from a light source 2 are turned to parallel beams LC through a condenser lens 3 and made incident upon the liquid crystal plate 1. When voltages applied to respective liquid crystal cells of the liquid crystal plate 1 are changed by a video signal, the transmitted light forms video light LD, condensed by a condenser lens 11, and then projected on a screen 4 through a field lens 5, so that the video formed by the liquid crystal plate 1 is expansively displayed on the screen 4. Since the optimum contrast direction of the liquid crystal plate 1 coincides with the direction of the optical axis (a), the contrast of the video obtained on the screen 4 is remarkably improved.

Title: Piezoelectric type switching valve
Inventor: FUJISHIMA HIROSHI
IPC: F16K31/00
Filed: 1985-02-15
Abstract: PURPOSE:To decrease the size of a device and to reduce a consumption power, by a method wherein a valve seat is formed to the both surface of the free end of a cantilever beam piezoelectric element located between 2 ports. CONSTITUTION:When a voltage is applied on a piezoelectric element 26, since the piezoelectric element is supported in a cantilever beam manner, the free end of the piezoelectric element is widely displaced upward. This causes blocking-up of a first port 16 by means of a valve seat 30a formed to the upper surface of the free end of the piezoelectric element 26. When a voltage is not applied on the piezoelectric element 26, a valve seat 30b at the free end of the piezoelectric element 26 is brought into a state to block up a second port 22. If a state, in that no voltage is applied on the piezoelectric element 26, is set as a stationary state, a consumption power can be decreased.

Title: Disk device and head suspension device
Inventor: KIMIHIRA TORU
IPC: G11B5/60
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To improve the positioning accuracy of head sliders in a head suspension device and to increase their resistance. SOLUTION: In this head suspension device, plate-like pair of arms 61-2, are lapped whose root parts are clamped with screw members 63, while top ends of lapped arms are fixed with adhesive 68-1 with each other. An arm module 70-2 has a higher rigidity as compared with that in a constitution in which top ends of lapped arms are free. Since lapped arms are fixed as an integral part, the rigidity of arm modules 70 become higher as compared with that in the constitutions in which arms are only lapped, thus, resonance points of the modules 70 become higher and amplitudes of top ends at resonances are kept small and the positioning accuracy of head sliders is improved.

IPC: C01B33/08
Filed: 1988-02-10
Abstract: PURPOSE:To recover especially useful SiCl4 in high efficiency, by concentrating a residual slurry of distillation, as it is or by heating at a lower temp. than the boiling point of AlCl3, thereafter by adding an aq. soln. of titanic acid and by concentrating by heating at a higher temp. than the neighborhood of the boiling point of AlCl3. CONSTITUTION:The aq. soln. of titanic acid is added dropwise to the residual slurry above-mentioned, introduced to a concentration vessel 3, while stirring below 50 deg.C in an inert gas atmosphere. Thereby, AlCl3 in the slurry is hydro lyzed to convert to non-volatile hydroxide. Continuously, the residual slurry is heated up to maximum 500 deg.C while stirring in an inert atmosphere to distillate liq. Si chloride and besides, finish its pyrolysis. That is, the residual slurry releases SiCl4 and polymer by heating 5 to leave granular solid. The evaporated SiCl4 and polymer are liquefied by cooling and recovered. The residual slurry after hydrolysis is taken out of the vessel 3 and abandoned after neutralizing with alkali. The amt. of this waste is below 5%, compared to the amt. when the total residual slurry is treated by neutralizing.

Title: Control method of recording current
Inventor: SATOU TSUGUO
IPC: H04N5/91
Filed: 1980-03-07
Abstract: PURPOSE:To facilitate an easy control of the recording current according to the level of the reproduced signal, by inserting and recording the discrimination signal of each recording head with every track during a dubbing and then discriminating the head of the recording mode with the discrimination signal during a reproduction. CONSTITUTION:In the case of a 5-fold speed dubbing, the signals reproduced from the tape 7 and through the heads 51-55 are recorded on the tape 8 by the reproducing amplifiers 91-95 plus the recording amplifiers 101-105 and via the heads 61- 65. In this case, the vertical synchronous signal VD is sampled out of the reproduced signal of the head 51 through the vertical synchronous separating circuit 11, and thus a blank part is recorded on the tape 8 at the period corresponding to the signal VD. The tape 8 thus dubbed is reproduced through the head VTR, and thus the position of the blank part has a shift with every field. Then a correspondence is given between the both blank parts to secure a discrimination among the heads 61- 65 during a recording. In such way, an easy control is possible for the record current.

Abstract: PURPOSE:To supply a stable constant voltage to a constant current circuit by composing a constant voltage circuit, which is provided with a band gap reference circuit, of an NPN bipolar transistor and obtaining a negative feedback gain by the two steps of the transistor. CONSTITUTION:A constant voltage source having the emitter of a transistor Q11 turns a voltage on the collector side of a transistor Q4 and a current flowing to a resistor R4 by a transistor Q9 and a resistor R5 to a constant current, and the voltage drop of the resistor R4 is made equal to the base/emitter voltage of the transistor.
