Title: Head carriage for video floppy device
Inventor: WAKABAYASHI MANABU
IPC: G11B5/48
Filed: 1987-05-29
Abstract: PURPOSE:To absorb the movement of a magnetic head due to during and contraction of an adhesive by setting an adhesive face in a track radial direction with relaxed specification accuracy by using the adhesive to adhere a magnetic head onto a carriage. CONSTITUTION:The titled carriage consists of a head base 36 with a magnetic head 3 placed on and fixed to one end and a carriage 2 with the head base 36 placed thereupon, and the head base 36 is fixed in the radial direction of the magnetic disk 31 of the carriage 2 by the adhesive. That is, the adhesive face between the magnetic head 3 and the carriage 2 is used as one face and the face is selected in a direction of track deviation (Y axis direction). Thus, the movement of the magnetic head due to curing and contraction of the adhesive is absorbed sufficiently and the mount accuracy is improved.

Title: Individually-packaging container for pushing out two liquids
Inventor: KOBAYASHI YOSHIHIRO
IPC: B65D81/32
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To mix liquids well with one touch, by forming a lid from a laminate film consisting of an inner layer having a zone where notches are made and a releasing agent is applied and an outer layer bonded on it, and by disposing the releasing-agent application zone into a proper position. SOLUTION: A lid is formed from a laminate film consisting of an inner layer having a zone where notches are made and a releasing agent is applied, and an outer layer bonded on it. In the case, the releasing-agent application zone is formed in the position where contents in both compartments are pushed out at the same time. Bending the container presses both the compartments against each other, causing to increase inner pressure in each, thereby pushing out the contents into the releasing-agent layer through the notched of the inner layer of the lid. Thus, the two kinds of contents are mixed together in the releasing-agent layer and pushed out from a push-out opening made in the outer layer.

Title: Chopper circuit commutation failure detector
Inventor: AWANO TOSHIAKI
IPC: H02M3/135
Filed: 1977-11-02
Abstract: PURPOSE: To detect the commutation failure due to shortness of an OFF pulse by resetting the ON pulse count with the OFF pulse of a chopper circuit.  
     CONSTITUTION: When a motor A in electric cars is controlled through a chopper circuit, one-shot circuit OS issues a detection authroization pulse and detects  commutation failure through the AND circuit with the output of a current detection  circuit CD, then counts the ON pulse by a counter CN and resets it with the OFF  pulse. When the ON pulse is consecutively output twice in stead of the OFF pulse,  an OR circuit combines this signal with the output of the AND circuit. Accordingly,  when the OFF pulse is not output due to circuit failure, it generates output. As a  result, the commutation failure can also be detected when there is shortness of the  OFF pulse.

Title: Foreign matter inspecting method
Inventor: YAGI YUTAKA
IPC: G03F1/84
Filed: 1990-05-22
Abstract: PURPOSE:To detect foreign bodies on the surface of a resist coating layer and in the resist coating layer by coloring the resist coating layer so that light in a 1st wavelength range is absorbed, but light in a 2nd wavelength range is transmitted, and measuring the quantity of only light in the 1st wavelength range in scattered light and the quantity of light including the 2nd wavelength range. CONSTITUTION:Detection light 12 includes the 1st and 2nd wavelength ranges, but the resist coating layer 11b absorbs the light in the 1st wavelength range and passes only the light in the 2nd wavelength range. Consequently, the light in the 1st wavelength range is reflected by the surface of the resist coating layer 11b and does not pass through the resist coating layer 11b and the light in the 2nd wavelength range is reflected partially by the surface of the resist coating layer 11b while the rest enters the resist coating layer 11b and is reflected by the surface of a metallic substrate 11a. The light 18a in the 1st wavelength range which is made incident on a 1st detector 20a is reflected light from the surface of the resist coating layer 11b and the foreign body 23a on the surface. The light 18b in the 2nd wavelength range which is made incident on a 2nd detector 20b, on the other hand, enables the foreign body 23b in the resist coating layer 11b to be detected.

Title: Alarm device for instrument
Inventor: KIDOKORO ISAO
IPC: G01R1/36
Filed: 1977-11-05
Abstract: PURPOSE: To achieve the reduction in operating force and obviate giving any influence to the running action of an indicating mechanism by using a steel ball at the acting point of cam thereby reducing the contact friction between the cam and actuator.  
     CONSTITUTION: When the traveling part of an indicating mechanism moves to the 100% scale side along the arrow on increasing of measurment input, its operating pin 6 engages in the groove of the arm 7 of an alarm device 15. The operating pin 6 then rotates the arm 7 from the position (a) to the position (b). When this position (b) is reached, the steel ball 22 of a cam 19 makes contact to an actuator 21 and rolls by exerting pressing force thereto, thereby actuating a micro-switch 10. Further when the measurement input increases, the operating pin 6 moves from the position (b) to the position (c), thus making the passage of the traveling part easy. At this time, the free end part 24 of the actuator 21 is curved to arc form and therefore even if the arm 7 passes by the position (b) being the actuating point of the alarm, the micro-switch 10 holds the actuating state.

Abstract: PURPOSE: To improve an integrating degree, by beforehand shooting ions in high concentration for separating an element to a collector buried layer, in a bipolar IC that previously forms the collector buried layer between an epitaxial layer making up the element and a substrate.  
     CONSTITUTION: An +  diffusion layer 2, a collector buried layer, is built up by diffusing a donor to one main surface of a p -  silicon substrate 1 in high concentration. An Si 3 N 4  film 4 as an impurity control film is formed on an SiO 2  film 3 produced in this process, and grooves 5 are made up by shallowly etching the n +  diffusion layer 2 at locations, which must function as separated regions 8. p + -type layers 6 are built up by shooting acceptor ions, the SiO 2  film 3 and the Si 3 N 4  film 4 are removed and an n-type semiconductor layer 7 is grown on that. Thus, the p + -type layers 6 are upward grown, and p-type element separated regions 8 can be formed. The processes of manufacture of a mask are decreased because ions can be diffused in self-alignment shapes in this way.
