Patent JP-S6012658-A (JP)
Title: Fluorescent lamp
Inventor: NAKAI KATSUMASA
IPC: H01J61/30
Filed: 1983-06-30
Abstract: PURPOSE:To maintain the luminous flux of a fluorescent lamp almost constant regardless of wide variation of the tube current by making almost equal the increase rate of luminous flux relative to increase in the tube current seen during a constant level of the coldest temperature of the tube wall and the ratio of decrease in luminous flux relative to increase in the tube current under a constant atmospheric temperature which accompanies the increase in the coldest temperature of the tube wall. CONSTITUTION:A fluorescent lamp 4 is constituted of the following members: an outer tube 1 forming an airtight space; an inner tube 2 which forms the same airtight space and the inner surface of which is coated with a phosphor; a pair of electrodes 3 and 3 coated with an electron-discharging matter and installed almost in the ends of the inner tube 2; and a rare gas and mercury vapor charged in the airtight space at several Torrs. The fluorescent lamp 4 is ignited with a power supply 5 through an ignition circuit 6 in such a manner that the coldest temperature of the wall of the outer tube 1 becomes 50 deg.C or above. In addition, when a change in luminous flux relative to the tube current while maintaining the coldest temperature of the tube wall at a constant level is supposed to be DELTAphi1 and a change in luminous flux caused by the change in the coldest temperature of the tube wall accompanying a change in the tube current is supposed to be DELTAphi2, they are adjusted according to the relationship DELTAphi1+ DELTAphi2 0. As a result, the luminous flux can be maintained almost constant regardless of wide variation of the tube current. Besides, an almost homogeneous illumination degree can be maintained regardless of variations of the power supply 5 and the ignition circuit 6.

Title: Data demodulating system
Inventor: TOOYAMA TERU
IPC: G11B20/14
Filed: 1982-07-12
Abstract: PURPOSE:To attain correct demodulation even with unstable front part of data, by detecting the demodulation of a bit signal of other sign before a demodulator demodulates a bit signal of a sign for a specified number of bits for resetting the demodulator. CONSTITUTION:A magnetic head 11 is broughto into contact with a magnetic medium such as magnetic bank book or the like at data reading, is moved relatively, reads out data from the magnetic recording medium and inputs the data to a demodulator 12. The demodulator 12 measures the interval of front bits for changing the time width of a data discriminating pulse, masks the data of the next bits and discriminates whether it is 1 or 0. The variable mask system is operated correctly even if the readout speed of data is changed and it is effective to a manual system or the like where the readout speed of data is not constant. A readout data RDD and a clock RCP are outputted via inverters I 1, I 2, and the readout data RDD from the inverter I 1 is on a high level when the data is 0 and on a low leel when 1.

Title: Manufacture of semiconductor device
Inventor: AKIBA TAKAO
IPC: H01L21/22
Filed: 1987-05-18
Abstract: PURPOSE:To reduce contact resistance by using an insulating film including an impurity as a diffusion source and diffusing the impurity through heat treatment from a contact hole. CONSTITUTION:An impurity layer 2 is formed onto a semiconductor substrate 1, and an insulating film 3 containing an impurity having the same type as the impurity layer 2 is applied onto the semiconductor substrate 1. A resist 4 is applied, and patterned through a photo-lithographic process. The insulating film 3 including the impurity is etched, using the resist 4 as a mask, thus shaping a contact hole. The resist 4 is removed, and heat treatment is executed, thus diffusing the impurity in the insulating film 3 into the impurity layer from the contact hole. Contact resistance can be lowered by applying a wiring material 5 because the concentration of only a contact section between the impurity layer 2 and the wiring material 2 is elevated.

Title: Pressure-controlling process
Inventor: SUGISAWA AKIRA
IPC: A23L3/12
Filed: 1984-06-12
Abstract: PURPOSE:Packages containing a relatively large amount of air are sterilized in such a sterilizer as the increasing rate of its inner pressure is varied near the time when the increasing pattern of the inner pressure of packages changes and the timing when the inner pressure of the sterilizer is delayed after the start of cooling of the packages whereby sterilization of packages of high air content can be ensured without damage or deformation of the containers. CONSTITUTION:Packages such as pouches of polypropylene-polyester laminate film including a food or water sealed are set in a sterilizer. The installation is tightly closed, raised in its temperature inside so that the increasing rate of the inner pressure is changed near the time when the increasing pattern of the inner pressure of the packages changes. Further, the start timing of the reduction in the inner pressure of the sterilizer is a little delayed than the start of package cooling to effect sterilization.

Title: Method for reducing strain of flip chip electronic device with underfiling
Inventor: THOMAS SUNIL
IPC: H01L21/60
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the strain of a solder junction, by making the cross section of each nozzle at the end of each supplying pipe larger as the distance of the nozzle from a central distributing pipe longer, and making the distribution factor of each distributing pipe for a deformable medium the same. SOLUTION: A distributor which controls a deformable medium 84 in a multiplexed state contains a central supplying pipe 83 through which the medium 84 is supplied with a very low pressure. A header 85 is connected to the central supplying pipe 86 and a plurality of distributing pipes 86, and each distributing pipe 86 requires a prescribed definite distance from the center of the supplying pipe 83. The end section of each supplying pipe 86 is formed in a nozzle. The cross section of each nozzle is correlated with the distance of each distributing pipe 86 from the center line of the central supplying pipe 83 and the nozzles having larger cross sections are positioned farther from the central supplying pipe 83. Based on this relation, the distribution factors of the distributing pipes 86 for the medium 84 can be made equal to each other.  Therefore, the strains of the dielectric layer of a chip and solder ball junctions of parts can be reduced to such values which are safe to the operation of the parts.
