Title: Magnetic recording and reproducing device
Inventor: SARUWATARI KIYOSHIGE
IPC: G11B15/665
Filed: 1989-02-21
Abstract: PURPOSE:To prevent a magnetic tape from flawing due to the occurrence of over tension on the tape by detecting a loading position at the time of unloading the magnetic tape and controlling the rotation of a reel base driving means in the loading position. CONSTITUTION:Post rollers 11 and 21 are moved along loading courses 3 to perform the unloading, and when they are brought under an intermediate state of unloading, a beam of light from a light emitting element 31 is interrupted by the post roller 21 not to come to a photodetector 32, and a signal of rotational operation instruction is sent by the photodetector 32 to a reel base driving source 15, and hence a reel base 14 is started to rotate so that the take-up of the tape is commenced. Consequently, the magnetic tape 2 is changed from a slackening state to an unslackening state, and since the take-up of the tape is carried out by the reel base 14 without abutting a magnetic surface of the magnetic tape 2 against a rotary head drum 102, the magnetic tape 2 is prevented from flowing by a frictional effect caused by a speed difference between tape speed and rotating speed of the rotary head drum 102.

Abstract: PURPOSE:To continuously manufacture fine and uniform silicon carbide of high purity by a short-time reaction by continuously feeding a uniform mixture of silica with carbon or a carbon compound to a rotary electric furnace kept at a high temp. under reduced pressure or in an inert gaseous atmosphere to bring the mixture into reaction. CONSTITUTION:A uniform mixture of silica such as fine powder of silica or white carbon or silica sol with carbon such as carbon black or petroleum coke or a carbon compound such as sucrose or glucose is continuously fed to a horizontal rotary electric furnace kept at >=1,400 deg.C under reduced pressure or in an inert gaseous atmosphere to continuously carry out the reduction and carbonization of the silica. Since the horizontal rotary electric furnace is used, a uniform temp. distribution can be formed, the starting materials are well mixed, and CO produced as a by-product is effectively diffused and removed. As a result, the reaction can be rapidly completed, and high purity silicon carbide having a small grain size is continuously obtd.

Title: Optical distribution coupler
Inventor: NAMIHIRA YOSHITAKA
IPC: G02B6/122
Filed: 1981-03-24
Abstract: PURPOSE:To obtain an optical distribution coupling where the loss is less and the higher mode is not generated, by coupling the output-side waveguide and N- number of input-side waveguides through a tapered waveguide where the diameter at one end is equal to that of the output-side waveguide and the diameter at the other end is N times as large as the diameter of input-side waveguides. CONSTITUTION:An output-side waveguideIhaving a diameter a1 and two input- side waveguidesIA andIB having the diameter a1 are coupled to both ends of a tapered waveguide III where the diameter at one end is a1 and that at the other end is 2a2. A specific refractive index is so set that the effective refractive index of these waveguides becomes uniform approximately. In respect to the tapered waveguide III, a tapered part has a length l2 long sufficiently for the wavelength of the light (250-1,000 times as long as the wavelength), and therefore, the generation of the higher mode is prevented, and the transmission loss does not exist in principle. Since diameters of input-side waveguidesIA andIB and the output-side waveguideIare a1 respectively, the connection loss is lessened. Generally, plural input-side waveguides may be used.

Filed: 1991-03-07
Abstract: PURPOSE:To apply a brake force to a rotor and to smoothly stop it by connecting a load resistor to a torsion driving piezoelectric element and consuming power generated at the time of stopping a motor. CONSTITUTION:A motor 1 is formed of a columnar stator 2 provided with a vertical vibration piezoelectric element 6 at an upper end and a torsion vibration piezoelectric element 4 on the way of an axial direction and a disclike rotor 3, and a load resistor 8 is connected to an electric terminal of the element 4 through a switching element 9. When the rotor 3 is stopped, energization by one driving power source 5 is stopped by the element 9, and the element 6 is driven by another power source 7 in a resonance frequency of the element 4. Since power generated at the element 4 upon reception of the torsional vibration of the stator 2 is consumed by the resistor 8, a frictional brake force of the rotor 3 with the output surface 2a of the stator 2 is alleviated, and the motor is smoothly stopped. The brake force can be freely regulated by changing the value of the resistor 8.

Title: Printer control device
Inventor: INAO HIROTOSHI
IPC: H04N1/32
Filed: 1987-02-27
Abstract: PURPOSE:To obtain identification information on interface impediment due to timing shaft delay between a printer and a controller by printing a counter mark outside a printing area when the end of a page is detected. CONSTITUTION:If a page end generation decoder 5 detects a page end, a page end signal 11 is generated. Simultaneously, a counter mark 15 is printed by a counter mark printing circuit 7. When the timing shafts of a printer and a controller match to each other, the counter mark 15 is printed at the rear end of a useable printing area 14. If any distrubance generates in the timing shaft of the controller, the counter mark is printed at a position which is not relevant to the rear end of the effective printing area. When the above method is used, the impediment of an interface can be traced back to its source, whether to the printer or to the controller, for identification when such an impediment generates, thus saving time for remedy.
