Abstract: PROBLEM TO BE SOLVED: To immediately abolish an invalid packet in a buffer by managing respective pieces of management data of the plural received packets stored in a storage area, receiving abolishment information and tags and detecting and abolishing management data having the tag applied to abolishment information. SOLUTION: An ATM switch 100 stores reception cells from input lines #1-4 in the common buffer SBM. In a control circuit CTL, an idle address pool IAP manages the non-use address of the common buffer SBM. An address queue AQ manages a write address Aw to the common buffer SBM of the reception cells and management data containing address and cell identification information CI. Cell identification information CI contains the tag identifying the call of the corresponding reception cell and the address. The control circuit CTL detects and abolishes management data applied to the abolishment cell from abolishment information of management data and the tag. Thus, the received cell in the common buffer SBM is immediately abolished.

Title: Recording apparatus
Inventor: HORI KEIICHI
IPC: B41J2/165
Filed: 1988-05-25
Abstract: PURPOSE:To prevent the evaporation and drying of ink, by separating an ink film from a thermal head or an ink coating part at the time of non-printing and further hermetically closing the opening part of a case by a seal member. CONSTITUTION:When a cassette is mounted on a recording part moving stand having a thermal head 12 placed thereon, the microporous film 17 trained over two guide rollers 18 under tension is in a non-contact state with respect to the thermal head and an ink coating part 9. The opening part 2 of a case is hermetically closed by a seal member 20 to prevent the evaporation and drying of ink. Since the thermal head 12 is moved rearwardly at a printing time so as to leave the ink coating part 9 provided in response to the thermal head 12, the thermal head 12 and the microporous film 17 become a contacting state in opposed relation to a platen 5. Therefore, the microporous film 17 trained over two guide rollers 18 under tension holds a definite angle and is internally brought into contact with the thermal head 12 and the ink coating part 9 to perform printing.

Title: Rotational frequency sensor and rotational frequency detecting method using sensor
Inventor: SAKAMOTO GUNJI
IPC: G01P3/44
Filed: 1985-06-12
Abstract: PURPOSE:To detect a rotational frequency with high precision by connecting the secondary winding of the 1st rotating machine of a rotor which rotates by being coupled with a stator and a rotating body to the primary winding of the 2nd rotating machine. CONSTITUTION:Rotary sensors 1A and 1B consist of the 1st and the 2nd rotating machines 4a and 4b which have the same constitution that a winding type induction motor has. The secondary winding L2 of the rotating machine 4a and the primary winding L1 of the rotating machine 4b are connected mutually, so a voltage of reference frequency from a reference voltage source 8 is applied to the winding L1 of the rotating machine 4a through a terminal t1 to establish a rotating magnetic field, thereby inducing a voltage of slip frequency accurately proportional to the rotating speed of the rotating body 7, i.e. rotor 3 across the winding L2 of the rotating machine 4b. Then, an arithmetic processor 9 calculates the frequency of the induced voltage from the reciprocal of the digital counted value of clock pulses to calculate the rotational frequency from the difference between the frequency and reference frequency.

Title: Degassing device for lsi package
Inventor: FURUMAE HITOSHI
IPC: H05K3/34
Filed: 1988-05-25
Abstract: PURPOSE:To realize degassing with a high mass-production efficiency by a method wherein a first spring presses down a second spring made of shape-memory alloy under a normal temperature and, under a soldering temperature, the second spring pushes up the first spring to make a valve pice leave an air passage hole. CONSTITUTION:As a spring 7 has a linear shape under a normal temperature, a spring 5 presses a hemispherical movable valve piece 6 against the cylindrical end of the bottom side of an air passage hole 10 by its own elasticity. Therefore, gas in the hole 10 and contact surfaces between a lead frame 3 and a resin package 4 does not flow out of the package. When the package 4 is dipped into a solder bath and the temperature of the package 4 reaches a soldering temperature, the spring 7 takes a V-shape stored and pushes up the movable end of the spring 5. Therefore, the movable valve piece 6 fixed to the spring 5 leaves the cylindrical end of the hole 10 and vaporized moisture in the package is made to flow out of the package through the hole 10 to reduce the gas pressure in the package. If the temperature of the package 4 returns to the normal temperature after the solder dipping, the spring 7 takes a linear shape again and the movable valve piece 6 is pushed down and pressed against the cylindrical end of the hole 10.

Filed: 1982-07-22
Abstract: PURPOSE:To obtain the accurate surface voltage distribution of a sample by storing the low and high magnification measurement data of the sample and positioning the sample position of the high magnification scanning based on the displayed positional information of section to be measured by the low magnification data. CONSTITUTION:When an aluminum pattern in the array block 31 of semiconductor memory 1 is accurately exposed to beams, scanning is stopped once after scanning the block 31 including another block in low magnification by the control of a SEM control section 9 for the first time. In this case, measurement voltage data is stored in a storage device 12. Then the data is read in the CPU16 after aligning a cursor with the center of the pattern to be measured of a displayed picture on a display unit 13. The CPU16 calculates the travel of a stage 8 and moves it. Furthermore, scanning is stopped once more after performing the high magnification scanning and the data is stored in a storage device 14. The CPU16 calculates the travel of the stage and moves it in the same way. Besides, the data is stored in the storage device 12 after performing the high magnification scanning. As a result, accurate voltage distribution can be measured by positioning the sample position using such a short time scanning.

Abstract: PURPOSE:To provide the subject mold not generating the gloss irregularity on the outer surface of a plastic molded product even when the mold is partially heated by a temp. adjusting core. CONSTITUTION:A mold (fixed mold) 1, the resin injection gates 2a, 2b formed to the fixed mold 1 and a plastic molded product (e.g. the cabinet of a television) 3, temp. adjusting cores 4a, 4b are shown. Thick parts 3a are formed in the vicinity of the bonded part of a resin heated by the temp. adjusting cores 4a, 4b. Since the parts near to the heated parts of the resin heated by the temp. adjusting cores 4a, 4b are thick, heat conductivity is bad and, since the parts remote from the heated parts of the resin have good heat conductivity, the temp. distribution receiving from the heated parts becomes uniform and the transfer property of the mold becomes uniform and the generation of gloss irregularity on the plastic molded product can be prevented.

Filed: 1987-05-27
Abstract: PURPOSE:To prevent the overheating of a transformer by a method wherein the temperature of the whole internal part of the transformer is accurately detected by the change in resistance with respect to the temperature of the winding, to be used to detect temperature which is wound around a coil bobbin. CONSTITUTION:The windings 2 and 4-7 to be used for operation of a transformer and a temperature detecting winding 3 are lap-wound around the coil bobbin 1 having flanges 8-1 and 8-2 on both ends. The temperature-detecting winding 3 is turned back in an intermediate part of the winding, and it is wound in such a manner that the winding direction of the part 3-1 on one side is reversed to that of the part 3-2 on the other side. Consequently, as the two inductances having the winding direction contrary to each other are brought into the form in which they are series-connected, the number of interlocking magnetic flux as the winding on the whole is set zero. Also, the temperature of the whole internal part of the transformer can be detected accurately.
