Title: Shield structure for electronic substrate and manufacture thereof
Inventor: KOMATSU NOBORU
IPC: H05K9/00
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To surely connect a substrate and shield materials with the minimum number of bolts and obtain a good shield performance by fixing the shield materials on the electronic substrate in an elastically deformed state. SOLUTION: This structure is constituted of an electronic substrate 1 and a shield material 10 which is made of electromagnetic shield substance and which is laid upon the electronic substrate 1 integrally with the substrate 1 and then is connected to the substrate 1. The shield material 10 is fixed on the electronic substrate 1 in an elastically deformed state. Due to this structure, an airtightness between the shield material 10 and the electronic substrate 1 can be maintained by means of stress generated by elastic deformation of the shield materials 10. In the case that the shield materials 10 which are projecting in the opposite directions are installed on both sides of the substrate, elastic forces of the shield materials 10 are offset and thereby the electronic substrate 1 does not bend.  Therefore, a shield performance can be surely maintained without using many tightening components such as bolts and a good electromagnetic performance is exhibited.

IPC: H01L21/324
Filed: 1989-06-28
Abstract: PURPOSE:To make it possible to improve microscopic electrical characteristics as well as macroscopic electrical characteristics by specifying heat treatment temp. and time when an ingot of the above crystal is heat-treated to improve electrical characteristics. CONSTITUTION:An ingot of an As compd. semiconductor crystal is heat-treated at a temp. between the m.p. and the m.p. -50 deg.C in As vapor for >=1 month. The heat treatment conditions depend on the kind of the As compd. semiconductor but the As compd. semiconductor crystal melts at above the m.p. In the case of a temp. below the m.p. -50 deg.C, e.g. in the case of the m.p. -100 deg.C, it is necessary to heat-treat the ingot for >=1 year and industrial trouble is caused. By this method, macroscopic and microscopic electrical characteristics in the surface of a wafer can be made uniform, specific resistance distribution in the surface is especially uniform and striation due to uneven concn. of impurities can be vanished.

IPC: E04H1/12
Filed: 1994-07-15
Abstract: PURPOSE:To make it easy to connect the leads and wiring and prevent water from entering in the connected part by bringing the connections between the wiring from indoors and the wiring inside the garbage-disposal equipment together adjacently to the ventilating fan inside the garbage-disposal equipment installed at the outer wall under a common covering for the electrical connections and the fan. CONSTITUTION:A garbage-disposal tank 1 is attached to the outdoor side of an outer wall 2. By opening an opening-closing lid 4 provided on the indoor side garbage produced indoors is thrown into the garbage-disposal tank 1 through a charging port and a duct 3. The garbage is disposed of by decomposition in the garbage-disposal tank 1 installed outdoors. In this instance a ventilating fan is provided on the inner side of the garbage-disposal tank 1, particularly at the position where the duct 3 has its side. Adjacently to the ventilating fan the connections between the wiring from indoors and the wiring inside the garbage-disposal equipment are brought together under a common covering 61 for the ventilating fan and the electrical connections. The connections of the necessary wiring are thus centralized at one spot and it does not occur for the garbage thrown in though the duct 3 to touch the wiring.

IPC: G01N27/26
Filed: 1988-06-30
Abstract: PURPOSE:To achieve a higher analysis efficiency by judging the presence of air bubbles within a capillary for migration from a potential change caused when a smaller fine current and a larger fine current are switched to be applied between a leading liquid electrode cell and a terminal liquid electrode cell. CONSTITUTION:After a terminal liquid electrode cell 2 is fed with a terminal liquid while a leading liquid electrode cell 4 and a capillary tube 5 for migration is fed with a leading liquid and then, a specified smaller fine current and larger fine current are made to flow between both the cells 2 and 4 continuously for a fixed time respectively. When no bubble exists in the capillary tube 5, a differentiated value of a voltage between both the cells 2 and 4 has peaks P1 and P2 appearing only when the currents are varied. Hence, after the checking of the appearance thereof, a sample liquid is injected into a sample injecting section 3. Then, a constant high voltage current is supplied between the cells 2 and 4 and a potential gradient is detected with a detector 6. When the peaks P1 and P2 are not normal, an electrolytic liquid is supplied again.

Title: Temperature detecting apparatus
Inventor: ICHIHARA TSUTOMU
IPC: G01J5/12
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To provide temperature detecting apparatus in which a thin-film thermistor is not broken down due to excess carriers and by which the detection sensitivity of a temperature can be enhanced by using the thin-film thermistor whose resistance value is changed largely even due to a very small temperature change. SOLUTION: When a voltage application means 3 applies a DC voltage respectively to one pair of electrodes 2, a prescribed electric field is generated across a plurality of protruding parts 21a at an electrode 21 and an opposite face 22a at an electrode 22 so as to be applied uniformly to the film-thickness direction of a thin-film thermistor 1. Then, the prescribed electric field accelerates carriers so as to be multiplied and generated cumulatively, the carriers which are endowed, with energy collide with atoms, and new carriers which are composed of electron-hole pairs are formed. The number of carriers is multiplied due to a so-called avalanche effect, a current which flows to the thin-film thermistor 1 is increased, and an output voltage is changed largely.  In addition, since the prescribed electric field is generated so as not to saturate the carriers, the thermistor 1 is not broken down clue to excess carriers, and the detection sensitivity of a temperature can be enhanced.
