Title: Inspection device
Inventor: YONEZAWA TOSHIHIRO
IPC: G02F1/13
Filed: 1987-11-24
Abstract: PURPOSE:To prevent the supporting base for the inspection device from running by itself even when the power source is turned off by braking the supporting base automatically even if movement control is disabled. CONSTITUTION:When a current is cut off with the main switch of the device, the exciting current of the exciting coil 19 of an electromagnetic brake 13a is cut off and an armature 18 presses a brake disk 16 fixed on a ball screw 4 with the pressure of a coil spring 20 to apply a brake. Therefore, the ball screw 4 is never rotated by the weight of the supporting base 3, so the supporting base 3 still stops without falling. Consequently, even when the supporting base 3 is held linearly or slantingly, or even in case of an external force, e.g., an earthquake in the horizontal state, the supporting base 3 is prevented from running by itself.

Title: Recovery of fluorine from water
Inventor: MATSUKURA HIROYUKI
IPC: B01D9/02
Filed: 1990-11-01
Abstract: PURPOSE:To recover fluorine in the crystal form of a pachnolite by adding to a fluorine-containing water at least one of the soluble salts of sodium, calcium and aluminum to form a specific pachnolite producing condition. CONSTITUTION:At least one of the soluble salts of sodium, calcium and aluminum is added to a fluorine-containing water to positively create a pachnolite producing condition in order to recover fluorine in the crystal form of a pachnolite. The aforesaid pachnolite producing condition permits the coexistence of fluorine ions in the water with sodium, calcium and aluminum ions. The crystal of the resulting pachnolite (NaCaAlF6.H2O) is recovered from the water by precipitation or filtration. The pachnolite is difficultly soluble in water but easily soluble in sulfuric acid. At this time, the fluorine is separated from the pachnolite to form hydrogen fluoride. In this way, the recovered fluoride can be reused as hydrogen fluoride. The hydrogen fluoride is used as a fluoride source in the preparation of various fluorine chemicals.

Filed: 1992-11-06
Abstract: PURPOSE:To acquire a pulse train of a rapid period by providing an active region which generates and amplifies light and an active Bragg waveguide region which consists of the same composition as the active layer and carries out oversaturation absorption and wavelength selection. CONSTITUTION:In an active region 21, light emission and amplification are carried out, and in a Bragg region 22, oversaturation absorption and wavelength selection are carried out. Light emission and amplification are carried out in a multiple quantum well layer 4 of the active region 21 and light is incident on the Bragg region 22 by injecting a current from a power supply 9 to an electrode 8. A diffraction grating structure 11 of the Bragg region 22 constitutes a composite resonator together with a main resonator formed at both ends of the multiple quantum well layer 4 and selects a wavelength of main resonator longitudinal mode. The multiple quantum well layer 4 is the same as the active region 21 and functions as an optical absorption layer by grounding an electrode 7. Absorption coefficient changes in accordance with light intensity and functions as an oversaturation absorber. Thereby, if intensity of incident light is increased, absorption coefficient there fluctuates and optical short pulse train is generated.

IPC: H04N9/78
Filed: 1990-11-05
Abstract: PURPOSE:To make the signal processing form of YC separation to be appropriate by forming a difference signal between two frames and a difference signal between two lines in a signal obtained by means of sampling a PAL color television signal with a sampling frequency which is four times as much as a color auxiliary carrier frequency and which matches with the phase of a color burst. CONSTITUTION:A difference between two frames and the difference between two lines in the signal obtained by sampling a P-signal with the sampling frequency which is four times as much as the color auxiliary carrier frequency and which matches with the phase of the color burst are formed in arithmetic circuits 8 and 9 and two kinds of the signals are extracted. At the samte time, two kinds of the signals are synthesized in a mixing circuit 10 by the signal of a movement, which is obtained by a signal processing, and it is set to be a C-signal. Thus, the moving signal without the mixing of the C-signal can be obtained by sampling the P-signal by the sampling frequency which is four times as much as the color auxiliary carrier frequency and which matches with the phase of the color burst. Since the omission of detection for the movement, which is to judge a moving picture to be still picture, is eliminated, the signal processing form of YC separation is prevented from being mistaken.

Filed: 1990-11-02
Abstract: PURPOSE:To absorb torque difference in change-over between an output cam and fuel consumption cam by correcting the opening of a throttle to equalize generated torque before and after the change-over. CONSTITUTION:A control unit 51 judges required torque from a signal of an accelerator operating amount sensor 53, calculates a throttle opening position needed to generate the required torque in the cam position obtained then from the output of a cam position sensor 58 and determines the opening of a throttle valve 57 through a servo motor 56. When the change-over of the cam is judged on the basis of the running condition, the opening of the throttle valve 57 in the change-over from a fuel consumption cam to an output cam is corrected to be reduced according to a torque difference between the change-over and desired one and absorb the torque increment. Conversely in the change-over from the output cam to the fuel consumption cam, the opening of the throttle valve 57 is increased to controllably correct the output for absorbing the torque difference. Thus, the cam can be changed over without any torque shock.

Title: Multicolor image forming device
Inventor: HIROBE FUMITAKE
IPC: G03G15/06
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent sticking of developer to a electrifying-means after the second one by applying biases to the shield and grid of at least the electrifying- means after the second one so that they are equal in potential to the developing DC bias of the preceding developing-means. SOLUTION: Relating to a re-electrifier 5 a high voltage is applied to a corona wire from a high-voltage power source 19 and corona electrification is conducted on the surface of a photoreceptor 1. Because the shield 5b of the re-electrifier 5 is grounded, an electric field in a direction opposite to that of an electric field generated by the corona wire due to a first latent image on the photoreceptor 1 is generated. Negative toner 20 on the surface of the photoreceptor is caused to fly to the shield 5b of the re-electrifier 5 due to the electric field in the opposite direction and soils the shield.  To counteract this, the potentials of the grid 23 and shield 5b are made almost equal to the potential of the preceding developing-bias 30, and a developing bias line from the bias power source 30 of the first developing-device 4 is used as it is for baises for the grid 23 and shield 5b of the re-electrifier 5.

Title: Thermal recording material
Inventor: IKEDA HARUHIKO
IPC: C07C43/225
Filed: 1985-12-28
Abstract: PURPOSE:To obtain a thermal recording material having excellent heat response characteristics and high sensitivity, by incorporating a specified compound. CONSTITUTION:A compound of the general formula, wherein R is a lower alkyl, is incorporated as a sensitizer, in a thermal recording material comprising a normally colorless or light-colored dye precursor and a color developer for developing the color of the dye precursor by reacting with the latter than being heated, whereby a thermal recording material having excellent heat response characteristics and high sensitivity is obtained. The sensitizer is ordinarily added in an amount of at least 5wt% based on the amount of the color developer. If the amount of the sensitizer is less than 5wt%, the sensitivity-enhancing effect is insufficient, whereas an addition of more than 400wt% of the sensitizer is inadvantageous on an economic basis. The dye precursor may be a compound based on triphenylmethane, fluoran, diphenylmethane, thiazine, spiropyran or the like. The color developer may be an acidic substance, i.e., an electron- acceptive compound which is conventionally used for a thermal recording paper. Particularly, a phenol derivative or an aromatic carboxylic acid derivative is used as the color developer.
