Abstract: PURPOSE:To strengthen the engagement with the binding lever at an end part position when external force is applied to an end member in a getting-out direction by providing the engaging protruding piece symmetrically provided with wing parts having engaging recessed parts and the two-split like slit continued to the engaging protruding piece from an end plate position. CONSTITUTION:Engaging recessed parts 17 are engaged with binding levers 9a to mount end members 12 on a binding member 10 and a pair of left and right contact protruding pieces 21 are respectively inserted in the inner surfaces of left and right engaging grooves 6a, 6b and the end plates 13 of the end members 12, 12 are in contact with the end surfaces of a back member 7 and, in this state, the binding member 10 is held to the back member 7. For example, when the wt. of bound base papers acts on the end members 12 as external force through the binding member 10 in this state, the external force in the same direction is also applied to the end edges of the engaging recessed parts 17. Hereupon, the left and right parts of the engaging protruding pieces 19 divided by slits 22 are inclined so as to be respectively opened outwardly centering around the closed end parts (a) of the slits 22 and this inclination direction is in a direction engaging the engaging recessed parts 17 with the binding levers 9a and, therefore, there is no possibility that wing parts 18 get out of the binding levers 9 unnecessarily.

IPC: C22B9/16
Filed: 1984-06-09
Abstract: PURPOSE:To shift the structure of the metallic bar to a unidirectional solidified structure and to eliminate defects such as blow holes by passing the metallic bar through a heating die having a molten zone. CONSTITUTION:An untreated metallic bar 4 in a die 1 is heated by a heating element such as an Ni-Cr wire at the outer periphery of the heating die 1 of graphite, etc. to form a molten metal zone 11, and the bar 4 is moved in the direction as shown by the arrow with pinch rolls 5 and 6. The inner wall at the outlet of the die 1 is heated to a temp. just above the solidifying temp. of the metal constituting the bar 4, and the metal which is melted in the die 1 is solidified at the outlet of the die 1 to obtain newly a metallic bar 12 consisting of a uniform solidified structure which is moved in the direction as shown by the arrow. When the cross section of the bar 4 is small, the leading end of the solidified part is protruded toward the inside of the die 1 as shown in the figure, and the segregation of the solute to the center of the bar 12 and the trapping of gas can be prevented. In case of necessity, the bar 4 is brought into contact with the dummy 15 of the bar 4 having a seed crystal of the single crystal 14 at the outlet of the die 1, the die 1 is heated, and a bar consisting of a single crystal can be obtained in the same process as mentioned above.

Title: Hook operation detecting circuit for telephone set
Inventor: HOSHIKA KENJI
IPC: H04M1/00
Filed: 1986-05-23
Abstract: PURPOSE:To easily and surely detect a hook operation independently of the distance from the place where a telephone is installed, by substituting the variation of a line voltage, which is varied with the switching of a hook switch, with the change of the charging/discharging current of a capacitor and detecting it by a photocoupler inserted and connected in series to the capacitor. CONSTITUTION:When the receiver of a telephone P is hooked off and a line voltage E falls, a discharging current I1 from a capacitor C is conducted to the light emitting diode element D2 of a photocoupler PC 2 and an output transistor TR T2 is turned on. When the receiver of the telephone set P is hooker on and the line voltage E is restored, a charging current I2 to the capacitor C is conducted to the light emitting diode element D1 of a photocoupler PC 1 and an output TR T1 is turned on. Thus, the hook switch switching state of the telephone set is surely detected independently of the distance from the place, where the telephone set is installed, if this circuit is connected in parallel to this telephone set, and the work for connection of various additional equipments is considerably simplified.

Abstract: PURPOSE:To obtain an adsorption type heat accumulator having desirable operability of wide application range for various utilities by utilizing heat absorp tion upon absorption and separation of operating medium to absorbent made of mixture of water and alcohols and heat absorption upon phase change of operating medium itself. CONSTITUTION:Operating medium 5 made of mixture of water and ethanol of liquid state is sealed in a vessel A1, absorbent 6 for adsorbing the medium 5 is sealed in a vessel B2, and both spaces are isolated via a switching valve 4 provided in a connection passage 3. When the valve 4 is opened at the time of heat sink to connect both the spaces, the medium 5 in the vessel A1 becomes vapor, is moved to the vessel B2, and started to be adsorbed to the absorbent 6. In this case, heat generation occurs due to the adsorption in the vessel B2 to raise its temperature, heat absorption is started due to the evaporation of the medium 5 in the vessel A1 to lower its temperature. Accordingly, the vessel A1 side utilizes the cold heat until the adsorption is equilibrated, and the heat can be utilized at the vessel B2 side.

Title: Throttle valve control device for internal combustion engine
Inventor: IBARAKI TOSHIKAZU
IPC: F02D41/22
Filed: 1993-05-21
Abstract: PURPOSE:To prevent deterioration of drivability by preventing overrunning of an internal combustion engine when abnormality occurs at a throttle controlling system, and thereby preventing excessive output controlling. CONSTITUTION:A sub-throttle valve 8 and a main throttle valve 9 are arranged on an intake passage 9, and an output of an engine 1 is controlled by cooperatively driving them. The sub-throttle valve 8 is opened and closed by driving a step motor 11 according to an operation rate of an accelerator pedal 10. When abnormality occurs at the sub-throttle controlling system, a reference engine speed at abnormality near the engine speed detected at the time of occurrence of abnormality is computed as fail-safe treatment. Intermittent fuel cuttings are so performed by injectors 5A to 5D in place of the sub-throttle valve 8 that the engine speed at the time of abnormality approaches the reference engine speed at abnormality. When the distance between the intermittent fuel cuttings reaches the specified value, the fuel cutting thereafter is omitted. Unnecessary output controlling of the engine 1 is thus prevented.

Filed: 1989-05-16
Abstract: PURPOSE:To prevent the generation of rolling-in of a material to a root part of the upper hub and a flange by specifying the reduction in area of the inner part of a stock inflow port of a cavity for forming the lower hub of parts. CONSTITUTION:When the upper punch 4 is allowed to descend after closing a stock 1 and forming of the stock 1 is started, first of all, the stock 1 flows to a cavity 2a for forming the upper hub 1a and a cavity 2b for forming a flange 1b and the upper hub 1a and the flange 1b are formed. Thereafter, when the upper punch 4 is further allowed to descend, the reduction in area is set to 50 - 80% and the stock 1 flows to the lower hub forming cavity 3a in which a material comes to scarcely flow and it is filled therewith. Therefore, it does not occur that rolling-in of the material to a root part of the upper hub 1a and the flange 1b is generated, and parts being free from a defect such as rolling-in, etc., can be obtained easily.
