Title: Spindle servo circuit for optical disk device
Inventor: EBARA KAZUNORI
IPC: G11B19/28
Filed: 1994-04-20
Abstract: PURPOSE:To prevent a spindle motor from runaway. CONSTITUTION:The speed of revolution of a spindle motor 8 is detected by using a magnet and a sensor 5 rotating together with the spindle motor 8. When the speed of the the revolution becomes a low speed revolution or a high speed revolution being out of the servo procession possible range by the IC1 for a CD and the IC for a CD-WO, the revolution of the spindle motor 8 is speedily made to be the speed of revolution within the servo procession possible range by switching over the driving control signal of the spindle motor 8 to the driving control signal SP2 outputted from a CAV servo system circuit with a runaway detecting circuit 9. As a result, since the motor becomes possible to be synchronized even when a tracking servo is not applied, even when a track jump is performed, or even at the time of starting the spindle motor 8, etc., the spindle never falls into a runaway state in which the motor 8 rotates at a lower speed or at a higher speed than the speed of a normal time.

Title: Optical fiber device
Inventor: URISU TSUNEO
IPC: G02F1/13
Filed: 1978-07-07
Abstract: PURPOSE: To make the device simple in constitution and small in size and enable it to be readily produced by acting an electric field or magnetic field upon the liquid interposed in the surfaces of optical fibers which are diagonally cut thereby changing its refractive index.  
     CONSTITUTION: Transparent electrodes 3, 4 are coated on the diagonal end faces of fibers 1, 2 and liquid crystal 5 is interposed between said electrodes and is applied with electricity from a power source 6. This liquid crystal 5 is able to change the refractive index which light L 2  senses when applied with an electric field. Now, the refractive indices of the fibers 1, 2 are assumed to be n and the refractive indices of light of the liquid crystal when not applied with any electric field and when applied with the electric field to be n 1 , n 2 . When, for example, n=n 1  and n 2  is so set that the light L 1  totally reflects at the interface of the fiber 1 and liquid crystal 5, then the light L 1  is transmitted from the fiber 1 to 2 when no electric field is applied but the light is not transmitted when the electric field is applied. Thereby the function as an interrupter of light may be made simple, with the constitution minaturized and the production facilitated.

Title: Optical card device
Inventor: SAITO AKITO
IPC: G11B7/00
Filed: 1988-04-05
Abstract: PURPOSE:To always accurately record/reproduce information by generating a synchronizing clock for recording/reproducing the information to correct the fluctuation of the relative moving speed between an optical card and an optical head. CONSTITUTION:The output signal of a rotary encoder 18 has a high frequency when the moving speed of a shuttle 15 is fast and has a low frequency in case of slow. Thus, when the moving speed of the shuttle 15 is fluctuated, the output signal of the rotary encoder 18 is fluctuated and a synchronizing clock to write a data in a modulation clock circuit 24 is generated in response to the fluctuation and supplied to a modulation circuit 22. Thus, even if the speed unevenness is not sufficiently corrected by a motor servo circuit 16, the information is always recorded accurately without being affected by the speed unevenness.

Abstract: PURPOSE:To enable high-speed copying without emitting offensive odor and  economical waste gas treatment with a simple and small-sized apparatus, by decomposing and deodorize a waste gas produced from an electrophotographic copying machine in presence of a heated oxidative catalyst. CONSTITUTION:An oxidative decomposition layer 4 in a honey-comb structure containing a catalyst, such as Mn2O3-Co3O4 or Ni-Pd carried with a carrier, such as alumina or diatomaceous earth is preheated with a heater 3 for activation, decomposes an offensive gas emitted from a copying paper through the fixing and conveying rollers 10 of the fixing device of a copying machine by the layer 4 and exhausts it out of the machine as a deodorized gas. An offensive gas, such as a solvent vapor emitted from a wet type copying machine, or a solvent left in a toner in a dry type copying machine, or a malodorous gas produced by decomposition of a binder, or the like is converted into an odorless and harmless gas. This apparatus is smaller than that of an activated carbon absorber, and requires smaller exchange frequency and lower operation cost. since deodorization is accomplished in a short time, this  method can be applied to a high speed copying machine.

Title: Suppression of formation of free formaldehyde from adhesive composition
Inventor: KIRITOOSHI KYOSHI
IPC: C09J161/20
Filed: 1992-04-06
Abstract: PURPOSE:To obtain an adhesive which can provide an improved working environment and is useful as wood or plywood adhesive by adding ammonium carbonate, ammonium bicarbonate or guanidine carbonate to an adhesive composition comprising an amino resin. CONSTITUTION:An adhesive composition suppressed in the formation of free formaldehyde is prepared by adding 0.1-10 pts.wt. at least one member selected from among ammonium carbonate, ammonium bicarbonate and guanidine carbonate to 100 pts.wt. adhesive composition comprising an amino resin such as a urea resin, a urea/melamine cocondensation resin or a phenol/melamine cocondensation resin. According to this process, the working environment can be markedly improved because the formation of a free formaldehyde odor in the mixing and agitation steps in a process for preparing an adhesive in the production of plywood can be markedly suppressed. Because the amount of the formed formaldehyde is reduced, the properties of this adhesive itself can be improved. Therefore it can be applied in a uniform coating weight, the temporary bonding during the production of plywood can be kept, and the workability is good.
