Abstract: PURPOSE:To restrict the amount of solder to a specified amount at the time of mounting, and improve the component reliability at the time of component mounting and after the mounting by installing a strip-type glass layer which is almost parallel to a mounting surface, on both ends of an electrode terminal arranged on two facing surfaces of a rectangular element. CONSTITUTION:A chip type electronic component is provided with an electrode terminal 2 on two facing surfaces of a rectangular element 1. A strip-type glass layer 3 parallel to a mounting surface is formed in said component. In this laminated ceramic capacitor 4, solder does not attach to the glass layer 3, so that the amount of glass is restricted to a specified value less than or equal to the glass layer. Thereby, the amount of solder can be restricted to a specified value, and the generation of cracks of the element 1 and the connection part between the element 1 and the electrode terminal 2 can be prevented, so that the reliability of a chip type electronic component can be improved.

Title: Semiconductor integrated circuit
Inventor: ISOWAKI HARUMI
IPC: H01L27/10
Filed: 1988-11-04
Abstract: PURPOSE:To prevent the data from leaking out by a method wherein the transfer gates transmitting the data stored in a ROM to outer terminals are controlled by signals and a pass word. CONSTITUTION:8 bit data stored in a ROM 11 are transmitted to an inner data bus 12 and transfer gates 13. When a correct pass word is inputted to an input terminal 17 in the case of a testing time, the logic circuit 16 outputs '1' coincident with '1' of the input T of an AND gate 15 so that '1' may be outputted to turn the transfer gates 13 ON allowing the data stored in the ROM 11 to be outputted to an outer terminals 14. Through these procedures, the said data can be prevented from leaking out.

Title: Motor
Inventor: NAKAGAWA HISAYA
IPC: H02K29/00
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To appropriately thin and flatten a motor. SOLUTION: In the motor, an air introduction hole 13 for communicating a negative-pressure region formed at an area to a stator set 11 due to the rotation of a rotor set 12 to the outside of the motor. Even if the negative pressure of the negative-pressure region formed between the stator set 11 and the rotor set 12 is becoming larger when the stator set 11 and the rotor set 12 are arranged closely or are rotated speedily, air outside the motor is introduced through the air introduction hole 13 into the negative-pressure region, thus preventing leakage of a lubricant through a bearing part 13 or the like to the outside by reducing the negative pressure at the negative-pressure region.

Title: Anaerobic and aerobic activated sludge process
Inventor: ICHIKAWA MASAHIDE
IPC: C02F3/34
Filed: 1990-10-18
Abstract: PURPOSE:To prevent the carry over of dissolved oxygen into an anaeration tank by the endogenous denitrification and endogeneous respipration in a mixing tank and to improve the efficiency of denitrification and dephosphorization by injecting a circulating nitrifying liquid into the mixing tank and mixing this liquid with return sludge, then returning the sludge to the anaeration tank. CONSTITUTION:The nitrifying liquid delivered from an aeration tank 6 by a pump P2, is injected from a circulating path 3 into the mixing tank 7 interposed in a return sludge path 4. The sludge settled in a final settling tank 2 is put into the mixing tank 7. The nitrifying liquid is also injected via the circulating path 3 by a pump P2. into the mixing tank 7 and is mixed with the sludge. The sludge mixed with the nitrifying liquid in the mixing tank 7 is intermittently returned by a pump P1, to the anaeration tank 5 in the front stage of the aeration tank 1. Since the nitrifying liquid is incorporated into the sludge in the mixing tank 7, the nitrate nitrogen in this nitrifying liquid is partly removed by the endogeneous denitrification. The dissolved oxygen is consumed by the endogeneous respiration.

Title: Digital signal reproducing device
Inventor: TAKI HIDEO
IPC: G11B20/10
Filed: 1989-10-26
Abstract: PURPOSE:To make a program searching operation swift by detecting whether a frame address should be renewed or not, inputting a signal for one frame into a memory, reading out a PCM data at a frequency rate corresponding to a reproducing speed and passing it through interpolation filter. CONSTITUTION:A frame address (h) is separated by a regenerative signal processing circuit 7 to be outputted to a frame address renewing decision circuit 9. This is compared with a value before the time by one frame in the circuit 9, and only in the case of noncoincidence, a frame address renewing output (i) is outputted to a memory control circuit 10. Only in the case of the renewal of an address, a PCM sound signal (f) is written to a memory circuit 8 by the circuit 10 with memory control output (j) in accordance with the output (i). Read-out is performed with a frequency corresponding to tape traveling information (b) to be given from a system control part 4. That is, if a speed is 1/4 of its usual speed, the read-out frequency should be dropped to 1/4 as well. Since a PCM signal memory output (k) from the circuit 8 is dropped in sampling frequency to 1/4, and hence quantization noise is entered into an audible band, the output is performed by bringing it back to the usual sampling frequency by using the interpolation filter 11.

Title: Induction heating fixing device
Inventor: TSUJIMOTO TAKAHIRO
IPC: G03G15/20
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To sufficiently uniformize the temperature distribution of a fixing roller in the longitudinal direction thereof without making the diameter thereof large by setting the length of a coil along in the axial direction of a heating rotary body to be longer than the effective length of the heating rotary body decided based on the size of a recording medium. SOLUTION: The length of the coil 14 along in the axial direction of the fixing roller 12 is set to be longer than the effective length of the roller 12 decided based on the size of a sheet 10. Thus, the distribution of magnetic flux at both end parts of the coil 14 is more reduced than that at the central part thereof but the flat distribution of the magnetic flux can be obtained by considering only the effective area of the roller 12. Then, induced electromotive force generated extending over the whole effective area of the roller 12 is uniformized and the density of a current at the central part of the effective area of the roller 12 becomes identical to that at the end parts.  As the result, since heat is uniformly generated extending over the whole effective area of the roller 12, the temperature gradient of the roller 12 in the longitudinal direction in the effective area becomes almost flat.
