Title: Seam detector of bottles
Inventor: KANOU TOSHITAKA
IPC: G01N21/90
Filed: 1978-05-31
Abstract: PURPOSE:To detect the seams of bottles accurately without making wrong recongnition of the same as flaws by letting the rays diffracting at the seams at the radiation of oblate rays be received in another photo detector. CONSTITUTION:Radiation of the oblate laser by a light source 2 combined with a slit or scanning mechanism transmits through a bottles 1 through the reflection and refraction intrinsic to the seam of the bottle 1 then passes through the optical path in the specific direction and is received in the photo detector 3B provided on this optical path. On the other hand, the diffused light owing to the flaw part or other of the bottle is received in the phtoto detector 3A provided on the oblate optical path. This constitution lets the seam of the bottle be accurately detected by the detection signals of the photo detectors installed in the required positions without making wrong recognition of the same as a flaw.

Title: Defatting and washing method
Inventor: KAWADA MASAHIRO
IPC: C23G1/00
Filed: 1984-03-30
Abstract: PURPOSE:To remove easily a lubricating agent for metal working by washing with water so that succeeding working such as plating is facilitated by using the lubricating agent prepd. by adding a nonionic surface active agent to a lubricating oil component and making said component into an emulsion with water as the lubricating agent for metal working. CONSTITUTION:Water is added to lubricating oil consisting essentially of the compsn. added with a nonionic surface active agent to lubricating oil such as mineral oil, fats and oils, etc. to prepare a lubricating agent in the form of an emulsion. Such agent is used in the stage of metal working. The lubricating agent sticking thereto must be removed in executing metal plating after the end of working. The lubricating agent having the above-mentioned compsn. can be extremely easily washed away by washing the same with water prior to drying and therefore the immediate starting of the succeeding plating treatment is made possible. The time required for the removing treatment of the lubricating agent is made extremely shorter than in the prior art and the water for washing is less consumed.

Title: Semiconductor device and its manufacture
Inventor: NISHI KENJI
IPC: H03K19/091
Filed: 1978-05-31
Abstract: PURPOSE:To form the polycrystal Si diode area to a desired value, by forming the collector layer of longitudinal NPN transistor with ion injection of P and As, and making thin the polycrystal Si layer. CONSTITUTION:The N epitaxial layer 22 on the N tupe Si substrate 21 is separated 23 to form the P type emitter layer 24 and the base layer 25. Next, As and P ions are injected to the layer 25 to form the N type collector layer 26. In this case, the peak position of the As concentration is very near to the surface of the N layer 26, and the peack position of P concentration is more than 0.2 mum in depth. Further, when the polycrystal Si 27 is provided and the P type diffusion is made on the entire surface, the N layer 26 is annealed, As is diffused upward, and the N layer 28 is caused under the layer 27 to form the pn junction. Next, the layer 27 is selectively peeled off to form the electrode 29. Since As slow in diffusion speed especially is used like this, the polycrystal Si can be made thin, the collector output resistance of NPN transistor is made small, and open wire can be reduced. Further, since P faster in diffusion speed is injected to the collector deep layer, the base width can be controlled.

Title: Dryer of sludge
Inventor: HAMADA TOSHINOBU
IPC: C02F11/12
Filed: 1979-05-23
Abstract: PURPOSE: To well dry the sludge charged into a drying chamber in a less number of treating days by force-feeding high-pressure air to the sludge to make it into porous shape and providing a means of drying the same by the utilization of the solar heat absorbed by a roof body.  
     CONSTITUTION: A roof body 27, painted black, is moved onto top of an upper block 6 of the drying basin. The water content of the sludge fed into a drying chamber 14 passes through a filter 11 and enters a water collecting chamber 15, from where it returns into the discharge basin through a water collecting head 7. When the sludge is concentrated, high-pressure air is fed from the water collecting chamber 16 to the sludge to let it expand to porous form. The hot air sucked through the air heating pipes 31 of the roof body 27 heated by solar heat is moved upward in the porous clearances of the sludge from the water collecting chamber 15 to let the water contact therein evaporate. When the heat exchanger pipes 32 suspended to the roof body 27 are heated, this transfers to the heat exchanger plate 34 in contact with the sludge to assist the moisture evaporation of the sludge. Upon completion of the drying, the roof body 27 is moved to the next drying basin.

Filed: 1981-04-30
Abstract: PURPOSE:To display the absolute value or reference frequency without interrupting the display function of the frequency deviation, by supplying after switching a counting value signal, the reference frequency signal and a deviation frequency signal, to a display device. CONSTITUTION:While a frequency deviation function switch is in off-state, a switch circuit 6 delivers the signal sent from a frequency counter 2 that counts the output signal of an oscillator 1 to a display device 5. When the frequency deviation function switch is turned on,the counting value of the counter 2 at that moment is stored in a storage circuit 3. Then the deviation frequency calculated at an arithmetic part 4 is displayed at the display device 5 via the circuit 6. On the other hand, the output of the circuit 6 is switched while a push switch for display of the absolute value or reference frequency of a switch circuit 7 is pushed. Thus the signal sent from the counter 2 or the circuit 3 is displayed at the display device 5. In such a way, the switching of display is possible while the frequency deviation display function switch is kept on.
