Title: Electric discharge lamp lighting device
Inventor: SUGINO MOTOHIRO
IPC: H05B41/392
Filed: 1993-12-20
Abstract: PURPOSE:To prevent feedback control from malfunctioning due to frequency fluctuations by detecting that the driving frequency of a switching circuit is out of a normal frequency range, and forcibly returning the frequency to the normal state. CONSTITUTION:The current of switching elements 4, 5 that is proportional to the current of an electric discharge lamp 7 is detected and compared with a predetermined reference voltage value and an electric discharge lamp is dimmed by control of an oscillating frequency from a current control oscillation source 11. This is the condition for the reference voltage being not more than a constant voltage value and for a lighting frequency being not less than a series resonance frequency f0. A circuit provided with a constant current source 16 and a transistor 18 and controlling the current of a transistor 19 in the same manner as with the oscillation source 11 is formed, and thereby when the oscillating frequency is lower than the resonance frequency f0 the output of a comparator 26 is inverted and an uncontrollable state is detected. In that case, a transistor 27 for connection to the comparator 26 is turned on and thereby the transistors 17, 18 are turned off, so the oscillating frequency reaches the highest frequency.

Abstract: PURPOSE:To provide the worked article of a noble metal which maintains the noble surface luster intrinsic to the noble metal, is improved in surface hardness and is prevented from surface deterioration and discoloration by coat ing its surface with a transparent thin film consisting of ceramics. CONSTITUTION:The surface roughness of a base body 1 of a ball marker for golf made of the noble metal consisting of, for example, gold, silver or the alloy thereof is improved and after this base body is washed, the transparent thin film 2 consisting of the ceramics is formed over the entire surface by a PVD method. This ceramics consist of, for example, aluminum nitride and has, for example, about 1 to 3mu thickness. The surface hardness is increased to the surface hardness of high-speed steels or above in this way and, therefore, there is no possibility of flowing at all and since the degree of adhesion of the thin film 2 is extremely high, the wear resistance is extremely high. Further, the thin film 2 is transparent and is extremely chemically stable and, therefore, the noble luster intrinsic to the noble metal is not lost and the deterioration and discoloration of the surface of the noble metal are prevented.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to restrain the rotation of a rotor satisfactorily even in a state that a driving signal is not supplied to an open-loop-shaped exciting coil by a method wherein a rotating magnetic field is given to the rotor by the open-loop-shaped exciting coil and a braking force is given to the rotor by a closed-loop-shaped braking coil. SOLUTION: Open-loop-shaped exciting coils 201, 202 to which an exciting signal is supplied and which give rotating magnetic fields to a rotor 22 composed of a permanent magnet and a closed-loop-shaped braking coil 201 which gives a braking force to the rotor 22 are provided in the circumference in the direction of rotation of the rotor 22. As a result, when a driving signal is not supplied to the exciting coil 201, e.g. when a power-supply switch 9 is turned off or when a product is shipped/conveyed, the rotor 22 is going to turn due to a vibration or the like. Then, since the braking coil 210 is formed to be closed-loop-shaped, an electromotive force is generated, a magnetic field due to the electromotive force acts as a braking force which does not turn the rotor 22, and it is possible to restrain the rotation of the rotor 22 satisfactorily.

Title: Spread spectrum communication equipment
Inventor: KAJIMOTO SHIGEKI
IPC: H04J13/00
Filed: 1988-12-19
Abstract: PURPOSE:To quickly take the synchronization of a pseudo noise code for spread demodulation at a receiver side by outputting a synchronizing stop signal having a prescribed time width in response to the detection of synchronizing step-out and stopping the synchronization acquisition and synchronization tracing and keeping the phase just before the pseudo noise code for spread demodulation for a prescribed period. CONSTITUTION:When a spread spectrum signal is not received at a sufficient electric field intensity at the interruption of communication or due to fading, a synchronous signal outputted from a Schmitt circuit 30 is lost. Then a synchronizing stop signal with a prescribed time width outputted from a one-shot multivibrator 54 is given to a clock phase shift controller 41. Thus, the frequency division ratio M is selected to be 100 till the absence of the synchronizing stop signal is discriminated after a prescribed time elapses or the synchronization is detected. Then the phase just preceding time of the pseudo noise code for spread demodulation is kept. When the synchronous signal is obtained and the synchronization stop is released, the synchronization is acquired already and the reception is attained by the synchronization tracing.

Title: Image projection system
Inventor: KNOX RICHARD M
IPC: H01J61/40
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To make an image projection device highly efficient. SOLUTION: Reflection polariscope 220 using double lightness reinforced film transmits P-polarized component and reflects S-polarized component of a beam of light from a highly efficient source of light 210. The transmitted P-polarized component is radiated onto an optical path to the screen via a mirror 250 and a projection lens 260. The reflected S-polarized light goes to a beam splitter/combiner 230 (hereinafter, combiner), wherein the light is split into blue, green, and red beams of light, and each of these light beams is radiated to reflection polarized light LCD 241 to 243 from a first to third surfaces of the combiner. These reflection polarized light LCDs polarize rays of a blue, green, and red light to return them to the combiner.  The returned light is united by the combiner again, and P-polarized light is transmitted and S-polarized light is reflected by the reflection polariscope 220. P-polarized component is radiated via the projection lens 260. Efficiency improves by polarizing and reusing a undesired polarized component.

Title: Cleaning solution for contact lens and cleaning method therefor
Inventor: SANJIYOU YUKIYASU
IPC: G02C13/00
Filed: 1990-11-24
Abstract: PURPOSE:To prepare a lens cleaning solution capable of checking the influence of the effective chlorine compound upon the lens and show a method of cleaning the lens, by using a surface-active agent having an excellent cleaning force and capable of decomposing the effective chlorine compound to neutralize and make harmless the same. CONSTITUTION:A cleaning liquid for contact lens is constituted by a first treating solution containing an effective chlorine compound and a second treating solution containing a surface activator having a particular effective chlorine decomposing capability. When a contact lens having dirt attached and fixed thereto is immersed in a mixture of the first and the second treating solution, the effective chlorine compound and surface activator synergistically act to remove the dirt of the lens. On the other hand, both react with each other whereby neutralization and making-harmless of the effective chlorine compound gradually proceed. Resultantly, it is possible to suppress the amount of the effective chlorine compound used to a minimum necessary value without impairing the dirt removal action. Therefore, it becomes possible to check the influence of the effective chlorine compound upon the lens. Further, the level of safety when the lens is fitted to the eye surface is remarkably enhanced.

Title: Control device for ignition timing of variable compression ratio type internal combustion engine
Inventor: UCHIDA MASAAKI
IPC: F02D15/04
Filed: 1987-12-18
Abstract: PURPOSE:To prevent knocking and the lowering of output by temporarily correcting ignition timing to the delay side and the advance side at the time of switching over from a high compression ratio to a low compression ratio and the other way around respectively. CONSTITUTION:A variable compression ratio type engine is controlled to be a high compression ratio (high epsilon) condition in a low load zone while being controlled to be a low compression ratio (low epsilon) condition in a high load zone, and the ignition timing is set on the delay side in the high epsilon condition while on the advance side in the low epsilon condition. At the time of switching over a compression ratio variable mechanism from a high epsilon to a low epsilon, a fundamental ignition timing is suddenly advanced. A first timer means 2 is operated by a compression ratio judging means 1 and, since the ignition timing is temporarily corrected to the delay side in accordance with the lapse of the time by a first correcting means 4, the deviation from a required ignition timing accompanying the delay in response of the compression ratio variable mechanism can be avoided. On the contrary, at the time of switching over from the low epsilonto the high epsilon, the ignition timing is temporarily corrected to the advance side. Hence, knocking caused by the overly advanced ignition timing or the lowering of output caused by the overly delayed ignition timing can be surely prevented.
