Title: Level shift circuit
Inventor: SUGANO MASAKI
IPC: H03K5/02
Filed: 1984-05-21
Abstract: PURPOSE:To avoid a low level of a binary signal fed to a logical circuit being of a negative level by connecting a series circuit comprising the 1st resistor and a diode between a comparator and the logical circuit and connecting the 2nd resistor between a connecting point between the diode and the logical circuit and a reference potential point. CONSTITUTION:An output of a comparator 2' is connected to a terminal 19 via a series circuit comprising a cathode/an anode of a diode 21 and a resistor 22. Then a signal obtained at a connecting point P4 between the diode 21 and the resistor 22 is fed to the logical circuit 1. When an output of the comparator 2' is a high level (+12V) and a low level (-12V), a binary output of a high level (+5V) and a low level (0V) shifted to the logical level at the logical circuit 1 is fed to the logical circuit 1. Since the resistors 20, 22 and the diode 21 only are used in this example, the circuit is constituted inexpensively. Moreover, the low level of the binary signal fed to the logical circuit 1 is set surely so as not to be a low level by selecting the resistors 20 and 22.

Title: Picture information recording and reproducing system
Inventor: YOSHIO JUNICHI
IPC: H04N5/92
Filed: 1988-04-25
Abstract: PURPOSE:To evade the display of an incomplete picture by writing a graphic code in a memory when a recording medium is played and when an end code is detected, notifying the presence of the graphic code and forming picture signals corresponding to the graphic code in accordance with a command. CONSTITUTION:A caption, musical score, or scene explaining sentence is inserted by using a sub-code into a moving picture obtained by video format signals recorded in a video area or a still picture obtained by a video memory. When the terminating end of a picture processing instruction group forming a picture over the whole area of a screen is detected thereafter, presence of picture signals by means of the sub-code is notified, but picture data read-out from a picture memory device 55 are not given to a CPU 58 and TCT 66 until a picture display by means of the sub-code is commanded through a key operation. Therefore, picture signals corresponding to a written graphic code is never formed before a series of picture information is written in the memory.

Filed: 1979-08-13
Abstract: PURPOSE:To manufacture the cold-rolled steel strip having excellent quality surface for processing purpose at low cost by a method in which a short-time soaking and the subsequent aging treatment following a quick heating are carried out in a nonreductive atmospbere and then film adhered to the surface of a steel strip is removed in the continuous annealing of the cold-rolled steel strip. CONSTITUTION:The cold-rolled steel strip manufactured by a cold rolling following a hot rolling is continuously annealed in the processes involving a quick heating, a soaking treatment, the primary cooling, an aging treatment, and the secondary cooling. In this case, the time required for the said whole annealing cycle is made shortest and its operational efficiency is raised by using a jet type direct-heating furnace for the quick heating treatment and also a film for raising the heat radiation rate of the surface of steel strip is formed by using an inorganic oxide, a blackcolored organic substance, or an iron oxide. And, a soaking treatment and an aging treatment are darried out in a nonreductive atmosphere or an oxidative atmosphere and also the cooling time is shortened by using a vapor-water cooling method. Lastly, the film on the surface of the steel strip is removed, the time required for the annealing cycle is shortened, and the working efficiency of the annealing is raised. Thus, the manufacturing cost can be reduced.

Title: Small pile for reinforcing foundation ground to earthquake
Inventor: OCHI KENZO
IPC: E02D27/14
Filed: 1986-05-07
Abstract: PURPOSE:To raise the reinforcing effect on foundation ground as well as to reduce the cost of construction work by a method in which a small pile whose high-rigid core periphery is bonded with a friction material having a great frictional force with sand is driven in groups into the foundation ground below or the side of a civil or building structure for reinforcement. CONSTITUTION:A friction material 3b composed of granular material, e.g., coarse sand, etc., is bonded to the periphery of a high-rigid core material 3a with the aid of an adhesive to form a small reinforcing pile 3. The small piles 3 are slightly penetrated into the bearing layer 4 of a sandy ground 1 where water level is comparatively high for foot protection or simply set on the surface of the bearing layer 4. The small piles 3 are also set with a more or less spacing from the surface of the bearing layer 4. In this case, the heads of the small piles 3 are separately positioned without being fixed on the donwnside of the roadbed 2a of a canalized road 2. Since the small pile 3 has high tensile rigidity and high compressive stiffness, the ground can be effectively reinforced and the construction cost can be reduced.

Title: Copying apparatus
Inventor: KAMIYAMA MITSUAKI
IPC: H01T19/00
Filed: 1979-08-14
Abstract: PURPOSE: To correct the charging potential and current quantity of a corona discharger according to using atmosphere temperatures, and make chargeability better and copying performance higher by providing the thermally deforming members which thermally deform according to the change in the atmospheric temperature of a photosensitive surface to the corona electrode.  
     CONSTITUTION: When the atmospheric temperature of the photosensitive surface becomes high owing to the generation of heat in each constituting apparatus etc. during copying, the bimetals 18, 18 provided to a charger 4 thermally deform upward with the fixed parts as a fulcrum and move a corona wire 16 in the charge release direction and this reduces the distance between the corona wire 16 and the photosensitive surface and increases charge receptive potential quantity by 100V,  from for exmaple, 500V, whereby it may be made to 600V being a permissible  potential quantity. In this way, the charge potential quantity of the charger 4 may  be corrected always to a permissible potential quantity, thus the chargeability of the  charger 4 may be improved, hence the copying performance may be improved.

Filed: 1979-08-15
Abstract: PURPOSE:To prevent the circuit from erroneous operation in response to noises from the outside and surges etc. by a method wherein a phototransistor or relay for prevention of erroneous working is inserted between the emittor of a photo-oscillation element and the gate of an auxiliary thyristor. CONSTITUTION:When an input signal is received, the phototransistor 11 is in ON condition, and a transistor 14 is put in OFF condition. When a source voltage drops under Zener voltage and a photo-oscillation element 6 turn on, the currents flow into the gate of the auxiliary thyristor 5 through a resistor 13 to turn the switching circuit on. When no input signal is received, the phototransistor 11 is put in OFF condition. At this time, even if the photo-oscillation element 6 makes an errneous works caused by the outside noises and serges, part of the currents flowing into the gate turns transistor 14 on passing thru a transistor 15 and the transistor 14 absorbs most of currents flow into the photo-oscillation element 6, so that no current flows into the gate of auxiliary thyristor 5 nor the switching circuit is erroneously operated.
