Title: Method for transporting pellets in air granulator and apparatus therefor
Inventor: MORITA SEIICHI
IPC: B29C31/04
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To transport pellets especially while preventing the mutual adhesion of them by allowing transport air to flow within a cutter case. SOLUTION: A resin material melted and kneaded by a kneading extruder is extruded into a cutter case 4 in a strand like shape from the nozzle of a die 2 and the strand like extrudate is successively cut by a cutter blade 3b to become pellets. Transport air always flows in the cutter case 4 from inflow ports 4b at two places and circulates within the cutter case 4 to flow out of a discharge port 4a. The granulated pellets are scattered within the cutter case 4 to fall and cooled during this period in air by circulated transport air. The pellets are gathered to the lower part of the cutter case 4 and discharged to a transport pipe 13 from the discharge port 4a along with transport air and transported to a storage device while further cooled in the mixed state with transport air within the transport pipe. Transport air flows along the inner surface of the cutter case 4 to cool the same.

Title: Heat shielding coating structure for burner
Inventor: TSUKAHARA SATOSHI
IPC: F23R3/08
Filed: 1984-05-14
Abstract: PURPOSE:To prevent cooling of a film from being affected by heat shielding coating and to enable decrease of the temperature of a liner wall surface, by a method wherein heat insulation coating is applied on a liner metal wall except a portion which is located on the downstream side of an injection nozzle for filmy air and extends a distance being 2 times as long as the height of an injection nozzle for filmy air. CONSTITUTION:A portion, extending by a distance l from the forward end of a lip 2 having film cooling structure, is prevented from being coated with a seal material 6. Coating is effected such that a spray nozzle 9 for a coating material is directed in a direction extending orthogonal to that of a liner wall surface 1, and this causes formation of a coated layer 5. From a point of view that the flow of a cooling air is uniformized, a contraction part and an expansion part formed right after the forward end of a lip may be prevented from formation, and heat shielding coating may be applied withing a range of a ratio of l/S being 2 or more. Thus, if a device is structured such that no heat shielding coating is applied within a range of a ratio of l/S being 2 or less, no effect by heat shielding coating is prevented from being exercised on cooling of a film, and this enables to display heat shielding properties being intrinsic in heat shielding coating.

Title: Tape guide of magnetic tape cartridge and its production
Inventor: SHIBA HARUO
IPC: G11B23/04
Filed: 1981-06-18
Abstract: PURPOSE: To obtain a tape guide which is easily produced with high travelling performance of a magnetic tape, by forming minute recessed and projected parts on the surface of a tape guide made of synthetic resin and accordingly reducing the contact surface with the magnetic tape.  
     CONSTITUTION: A synthetic resin having ≥0.8% molding contraction rate is injected into a single metal mold and then cooled in the mold. The synthetic resin is taken out after the contraction. In such way, a tape guide 20 having a 6mm outer diameter with minute recessed and projected parts is obtained easily with a 0.005W0.02mm depth at the recessed part 32 plus a 0.01W0.1mm width and 0.05W0.15mm space at the projected part 34 respectively. In such constitution, the contact surface between the guide 20 and a magnetic tape is reduced along with a reduction of the friction force to ensure the stable travelling of the tape. The recessed and projected parts can also be formed with numbers of minute projections to obtain the same effect.

Title: Ultrasonic wave transmitter/receiver
Inventor: UMEHARA YOICHI
IPC: G01S15/96
Filed: 1985-05-02
Abstract: PURPOSE:To facilitate the comparison of reflected waves of two frequencies, by arranging a transmitter/receiver which transmits or receives an ultrasonic wave of a relatively high frequency while receiving an ultrasonic wave of a relatively low frequency and a transmitter for transmitting an ultrasonic wave of relatively low frequency. CONSTITUTION:A transmitter 2 is driven by an output signal of a second transmitter section to transmit an ultrasonic wave of 50kHz. A transmitter/receiver 1 is driven by a first transmitter section to transmit an ultrasonic wave of 200kHz and receives the reflected wave thereof while receiving the reflected wave of the ultrasonic wave of 50kHz being transmitted from the transmitter 2. In other words, the transmitter and the receiver are combined on the high frequency side while on the low frequency side, the transmitter and the receiver are separated in substance, thereby reducing the trailing in the oscillation line on the low frequency side. This facilitates the comparison of reflected waves of two frequencies, thereby enabling accurate detection.

Title: Motor control device
Inventor: SODA ATSUSHI
IPC: H02P29/00
Filed: 1994-05-09
Abstract: PURPOSE:To form a motor control device allowing the speed of revolution of a motor to change in a state in which a phase lock is always held even in the case a tape running speed is changed as compared with a normal reproducing. CONSTITUTION:When a tape speed command is changed with respect to a drum motor 13, the revolution frequency of the drum motor 13 is allowed to change while holding the phase lock with a phase comparator 4 by limitting the change quantity per a unit-time of a program play mode reference signal with respect to the change of the tape speed command. Thus, since a head can trace a helical track and the omission of data and the needless repeat of data are not generated, qualities of a reproduced video and a reproduced voice are improved.

Abstract: PURPOSE: The dehalogenation of a halogenated substituted phenylacetic acid gives a phenylacetic acid used as a modifier for antibiotics or synthetic intermediate for  anti-inflammatory analgesic in high yield with industrial advantage from the view  point of the price of the starting materials as well.  
     CONSTITUTION: The catalytic hydrogenolysis of halogenated substituted phenylacetic acid of formula I (X is halogen; R 1 , R 2  are H, lower alkyl; R 3  is H, lower alkyl, hydroxyl), preferable 3-chloro-4-hydroxy-phenylacetic acid, is conducted in a solvent mainly consisting of water, lower alcohol or their mixture in the presence of a strong acid such as sulfuric acid to cause the dehalogenation and form a phenylacetic acid of formula II, preferably 4-hydroxyphenylacetic acid. Since the compound of formula I is readily derived through mandelic acid derivative from glyoxylic acid and o-chlorophenol, the present process is superior to existing processes from view point of the costs of the starting material as well.

Title: Forming method for metallic tube
Inventor: MIKI SUMIO
IPC: B21D22/16
Filed: 1981-06-22
Abstract: PURPOSE:To manufacture a thin, long metallic tube of excellent cylinder accuracy by changing a mandrel to make the clearance between the material tube and the mandrel small when making spinning work of a metallic tube while rotating the tube fitted to the mandrel. CONSTITUTION:A thick metallic material tube 3 is fitted to a mandrel 1 one end of which is fixed to a rotation shaft 2. While rotating the mandrel 1 by the rotation shaft 2, a forming roller 4 is rotated and moved in axial direction of the mandrel 1, and the material tube 3 is extended to form a thin material tube 3'. When inner diameter of the formed material tube 3' becomes larger than the mandrel 1, the mandrel 1 is changed to that of larger diameter, and spinning is performed by the roller 4. Since clearance between the two is small, there is no generation of complicated stress such as bending moment as in the case when there is a clearance. Thus, a thin metallic tube excellent in cylinder accuracy can be formed easily.
