Title: C-axis device with variable brake
Inventor: YUZUHARA HIDEO
IPC: B23Q15/08
Filed: 1990-09-29
Abstract: PURPOSE:To improve the stability in C axial position control, by increasing a brake pressure so that a detected position following error becomes less than an allowable value and also performing a pressure control so as not to exceed a threshold brake pressure. CONSTITUTION:When a milling work is started with a cutting feed by a C axis driving, a solenoid changeover valve 7 is changed over with a solenoid SOL1 being actuated with voltage being fed from a brake ON/OFF circuit 19, a disk brake 4 is actuated and brake is put on a spindle 1. The brake pressure of the disk brake 4 is increased in the case of the following-up error being larger than a reference value, with a position following-up error and the allowable value stored in a memory circuit 22 being compared by a brake pressure control circuit 23. When the following-up error becomes in a slightly small value than the allowable value, it is confirmed that the brake pressure is smaller than a threshold brake pressure or not, and in the case of the brake pressure being equal to a threshold pressure or becoming larger, cutting is continued with the brake pressure being set at the threshold pressure.

Abstract: PURPOSE: To prepare the compounds readily by reacting adjacent dichloro- or dibromo-alkanes, α,ω-dichloro- or dibromo-pentane, α,ω-dichloro- or dibromo- hexane with silicon.  
     CONSTITUTION: When alkenes, cyclopentane or cyclohexane are prepared from the adjacent dichloro- or dibromo-alkanes, α,ω-dichloro- or dibromo-pentane or α,ω-dichloro- or dibromo-hexane, respectively, the objective compounds are readily obtained by reacting the starting materials with silicon to cause dehalogenation and cyclization. It is preferable to use the silicon having a small particle sizes because the reaction is heterogeneous. The silicon or silicon alloy in the form of powder or grit having an average particle seize of 0.05-0.5 mm are preferably used. The by-products of bromo- or chlorosilanes can be used in the various fields.

Title: Acoustooptic switch
Inventor: FUJITA MASAYUKI
IPC: G01M11/00
Filed: 1986-10-31
Abstract: PURPOSE:To prevent diffraction grating from decreasing and an optical axis from shifting in position by varying the output sine wave frequency of an electric circuit which drives an acoustooptic element. CONSTITUTION:The acoustooptic element 50 is so set that the angle of incidence of light of 1.3mum in wavelength from a fiber 20 to the element 50 satisfies Bragg conditions at the output sine wave frequency of 140MHz of the electric circuit 90. The circuit 90 has a crystal oscillator of 140 and 117.42MHz internally and switches its output frequencies with an external signal. Therefore, an acoustooptic switch can be put in operation while the angle of incidence of the light from the fiber 20 to the element 50 satisfies the Bragg conditions without changing optical system settings. Consequently, a decrease in diffraction efficiency and the shifting of the optical axis are precluded for light with various wavelengths.

Title: Formulation for improving preservation quality of food
Inventor: SHIMAMURA UMAJIROU
IPC: A23B4/12
Filed: 1985-11-22
Abstract: PURPOSE:To suppress deterioration in springiness and water holding property of a product by elution of an organic acid in milling treatment and change in taste thereof, etc., by using adipic acid as the organic acid in a formulation for improving preservation quality of food prepared by coating the organic acid with a fat or oil. CONSTITUTION:A formulation for improving preservation quality of food, obtained by suspending coarse granular adipic acid in a molten fat or oil, homogenizing the suspension to convert the coarse granular adipic acid into a fine particulate or granular material having 20-50mum average particle size and particle size distribution of <=2wt% particles having >=100mum particle size and >=60wt% particles having <=30mum particle size and spray cooling the resultant material and consisting of a granulated material containing the adipic acid as a core material coated with the fat or oil. The formulation is particularly suitable for marine and livestock paste products. Since the coating is sufficient, the ratio of the organic acid to be eluted in milling treatment is slight and the springiness and water holding property of the product are good. The organic acid is eluted in heat treatment to exhibit the preservation quality.

Title: Contact opening/closing device
Inventor: KANEMOTO NAOKI
IPC: H01H33/16
Filed: 1992-09-30
Abstract: PURPOSE:To provide a contact opening/closing device further excellent in deposition resistance. CONSTITUTION:A contact opening/closing device is provided with a low- resistance contact block A having a pair of openable/closable low-resistance contacts 1, 2 and connected between external load circuits and an arc contract block B having a pair of openable/closable arc contacts 6, 7 excellent in fusion resistance. A high resistor 10 is connected between both contact blocks A, B to form a parallel circuit so that the arc contacts 6, 7 are brought into contact with each other before the low-resistance contacts 1, 2 at the time of a closing action and opened later at the time of an opening action. The arc contacts 6, 7 bear arcs at the time of opening/closing actions of contacts, a load current flows in the low-resistance contacts 1, 2 at the contact state of the contacts to suppress the temperature rise, and the high resistor 10 is not fixed directly to the contact portion. The contact opening/closing device hardly suffers from the limitation to deteriorate fusion resistance such as the thinning of the contact thickness and various stresses due to the opening/closing of current, and the rush current of a capacitor can be stably suppressed to a small value.

Filed: 1991-10-09
Abstract: PURPOSE:To stably accurately miniaturize by etching while adding nitrous ions or chemicals for generating the nitrous ions into treatment solution. CONSTITUTION:A wet treatment such as cleaning or etching is executed by using mixed acid containing fluoric acid and nitric acid as main ingredients as treatment solution. In such an etching method, etching is executed while adding nitrous ions or chemicals for generating the nitrous ions into the solution. For example, a silicon substrate is etched by using selective etchant containing 49%-fluoric acid, 61%-nitric acid and 99.5%-citric acid. In this case, a variation in NOx concentration in vapor state is sensed to indirectly detect a change in concentration of nitrous ions, nitrous sodium (1mol/l) is added to be etched in response to the detected value. As a result, 1ml of aqueous nitrous solution is added to 1.2l of etchant at each 10-30min.

Title: Address generating method
Inventor: KITAGAKI KAZUKUNI
IPC: G06F17/14
Filed: 1990-09-29
Abstract: PURPOSE:To obtain an address generation method capable of generating the reading addresses of a coefficient memory by using a value obtained by inverting successively generated continuous lower (m-1) bits as the reading addresses of the memory storing coefficients and executing time thinning fast Fourier transform. CONSTITUTION:An address generation circuit is constituted of a k-counter 1 and a variable width bit inverting circuit 3. In the case of generating the addresses of coefficients for fast Fourier transform (FFT) e.g., the k-counter 1 increases its count value one by one from '0' at twice the address generation period of data and repeats its counting by a number corresponding to the number of points and a stage number. When bits corresponding to the number of points of FFT are reversely operated by the circuit 3, the prescribed addresses of the coefficients can be obtained. Thus, the addresses of the coefficients are generated and the circuit size of the address generation circuit is sharply reduced.

Title: Movie technique on television for expressing stereoscopic picture by varying scan period
Inventor: TSUKADA HIDEO
IPC: G03B35/00
Filed: 1986-11-04
Abstract: PURPOSE:To obtain stereoscopic pictures by taking out an object as tomographic pictures corresponding to distances and increasing the number of times of picture projection according as the distance is shorter. CONSTITUTION:The object is tomographically photographed in accordance with distances. Obtained tomographic pictures are expressed with the scan period varied so that the picture corresponding to a shorter distance has a shorter picture projection cycle and a higher picture density. Thus, stereoscopic pictures are obtained without using special spectacles because pictures whose number of times of projection is smaller look deeper to bring about perspective.
