Title: Optical disk device
Inventor: WACHI SHIGEAKI
IPC: G11B7/085
Filed: 1987-06-18
Abstract: PURPOSE:To move a fine actuator relatively against the eccentricity and zigzag of a recording track by driving the fine actuator based on a repeated signal component of a tracking error signal. CONSTITUTION:A selection circuit 45 switches a contact in response to a seeking signal SSK and outputs an error signal outputted from an operational amplifier circuit 74 to a rough actuator 37 in stead of an output signal from an operational amplifier circuit 40. Thereby, the rough actuator 37 is controlled at its drive so that an error signal between a speed detecting signal SV and a drive control signal SDR becomes 0V, and at the time of seeking, servo control is executed so that the signal SV coincides with the signal SSD in stead of a tracking error signal STE. When the fine actuator 35 is driven by a repeated signal component extracted from the tracking error signal STE, an optical head does not cross the recording track by the eccentricity and zigzag of the recording track other than seeking operation, so that the generation of miscounting of a traverse count value can be prevented.

Title: Silver halide photographic sensitive material
Inventor: KIYOHARA KAZUTO
IPC: C08L33/04
Filed: 1990-06-12
Abstract: PURPOSE:To prevent light piping phenomenon without degrading transparency by specifying the surface refractive index of a plastic film to <=1.60. CONSTITUTION:The photographic sensitive material is produced generally by coating the surface of the plastic film base with at least one layer of photographic sensitive layers. The surface refractive index of this plastic film is specified to <=1.60. The plastic film having <=1.60 surface refractive index refers to the film in which the refractive indices in the plane and thickness directions of the film are both <=1.60. The distance at which light arrives from the film edge by the light piping is shorter as the refractive index of the film is more approximate to the refractive index of the film. The film is usable with substantially no harms, insofar as the refractive index is <=1.60 when the thickness is 100mum and the film is used as a rolled negative film. The light piping phenomenon is prevented in this way without degrading the transparency and the photographic performance is not impaired at all.

Title: Method and apparatus for chemiluminescence analysis
Inventor: INOUE KASHIRO
IPC: G01N21/76
Filed: 1984-07-25
Abstract: PURPOSE:To make it possible to perform selective receiving and detection of the light only from chemiluminescence caused by an inorganic hydride, by leading the starting time of chemiluminescence reaction of a sample gas and ozone faster than the time when radiated energy is received and detected by a sensor. CONSTITUTION:A sample introducing pipe 2 and an ozone introducing pipe 1 are connected immediately before a first reaction chamber 3. When these gases are mixed in the reaction chamber 3, luminescent reaction is yielded in the chemiluminescence material in a sample gas at the same time. The chemiluminescence caused by NO in the sample gas is attenuated before the mixed gas enters a second reaction chamber 4. The luminescence for long duration based on an inorganic hydride is continued in the second reaction chamber 4. The light is inputted to a sensor 7 through an optical window 5 made of quartz and the like, which pass all the wavelength higher than 170nm. Thus, the chemiluminescence analysis of the inorganic hydride in the sample gas can be carried out without the obstruction of NO.

Title: Method for controlling distribution of braking force of vehicle
Inventor: SUGIMOTO YOICHI
IPC: B60T8/58
Filed: 1995-06-20
Abstract: PURPOSE: To lessen a ratio of distribution of braking force for a light-loaded rear wheel in an inner side of cornering and to avoid losing the braking force and to increase transverse force by changing an aiming speed difference of the wheel of the inner side of cornering when a vehicle is cornering such that it is larger than the speed difference when the vehicle is running straight. CONSTITUTION: A correction factor K corresponding to the difference between a setting wheel diamter and an acutal wheel diameter is calculated by a ECU 6 based on the ratio of the rotation speed of a front wheel to that of a rear wheel, while a vehicle is running, and the speed of the front wheel among the speeds of the front and the rear wheels is corrected by the correction factor K. An amount of control of brake pressure adjusting means 41 , 42 is calculated based on the speed of the rear wheel and the speed of the front wheel after correction.  On the other hand, when the correction factor greatly changes because of slip of a driving wheel on a slope, the calculation of the amount of control is prohibited based on the compared results of the speeds of the front and the rear wheels to preclude the unnecessary control of distribution of braking force caused by the change of a moving radius of the tire in a short time and then the amount of control is calculated so as to obtain a ratio of brake hydraulic pressure depending on the decelerating rate of the vehicle body.
