  • Publication number: 20180246258
    Abstract: Influence of chipping in case of dicing a plurality of stacked substrates is reduced. Provided is a semiconductor device where a substrate, in which a groove surrounding a pattern configured with a predetermined circuit or part is formed, is stacked. The present technology can be applied to, for example, a stacked lens structure where through-holes are formed in each substrate and lenses are disposed in inner sides of the through-holes, a camera module where a stacked lens structure and a light-receiving device are incorporated, a solid-state imaging device where a pixel substrate and a control substrate are stacked, and the like.

  • Publication number: 20180217361
    Abstract: Substrates with lenses having lenses disposed therein are aligned with high accuracy. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are direct-bonded and stacked. In particular, one or more air grooves formed in surfaces of the substrates reduces an influence of air inside a void portion between adjacent lenses of a layered lens structure.

  • Publication number: 20180203164
    Abstract: Substrates with lenses having lenses disposed therein are aligned with high accuracy. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are direct-bonded and stacked based on an alignment mark. The alignment mark is formed simultaneously with the through-hole. The present technique can be applied to a camera module or the like in which a stacked lens structure in which at least three substrates with lenses including first to third substrates with lenses which are substrates with lenses in which a through-hole is formed in the substrate and a lens is formed on an inner side of the through-hole is integrated with a light receiving element, for example.

  • Publication number: 20180196170
    Abstract: To suppress occurrence of contamination or damage to a lens. In the present technology, for example, a manufacturing apparatus allows a spacer which is thicker than a height of a lens resin portion protruded from a substrate to be adhered to the substrate. In addition, for example, in the present technology, the manufacturing apparatus molds the lens resin portion inside a through-hole formed in the substrate by using a mold frame configured with two layers of molds and, after molding the lens resin portion, in the state that one mold is adhered to the substrate, the manufacturing apparatus demolds the substrate from the other mold. The present technology can be applied to, for example, a lens-attached substrate, a stacked lens structure, a camera module, a manufacturing apparatus, a manufacturing method, an electronic apparatus, a computer, a program, a storage medium, a system, or the like.

  • Patent number: 8074444
    Abstract: An exhaust emission control device has an additive valve and a control unit to decrease nitrogen oxides contained in an exhaust gas by means of a reducing agent. The control unit sets a valve opening period of time and a valve closing period of time alternately elapsing in a repetition cycle. The control unit controls the valve to discharge the agent into the exhaust gas during each valve opening period and to stop discharging the agent during each valve closing period. The control unit sets the valve opening period to be shortened as a flow rate of the exhaust gas is lowered, so that a penetration force of the reducing agent is appropriately set. The control unit sets the repetition cycle at a value depending on the flow rate of the nitrogen oxides to sufficiently deoxidize the nitrogen oxides by means of the agent.

  • Patent number: 7801658
    Abstract: The output torque of an in-vehicle engine is controlled based on the larger one of a pedal torque set by a pedal torque setting section in accordance with an operation amount of an accelerator pedal and a cruise torque for cruise control set by a cruise torque setting section. At the time of starting the cruise control, an initial value of the cruise torque is set by an initial value setting section as the smaller one of the torque required for traveling a vehicle at a constant speed of a target vehicle speed and the pedal torque.

  • Publication number: 20080256931
    Abstract: An exhaust emission control device includes a reducing agent adding valve for injecting a reducing agent into an exhaust pipe. The adding valve has a tip end portion having a nozzle and facing an internal space of the exhaust pipe. The tip end portion is disposed outwardly of an inner circumferential surface of the exhaust pipe. The adding valve is kept out of direct striking contact with the exhaust gas and hence is substantially free from thermal degradation and adhesion of deposits.

  • Publication number: 20080155973
    Abstract: An exhaust emission control apparatus is provided which is equipped with an additive injector to inject additive such as a urea aqueous solution into an exhaust pipe through which exhaust emissions flow. The exhaust pipe includes a straight section and a bent section. A catalyst such as a SCR (Selective Catalytic Reduction) catalyst is disposed downstream of the straight section. A hollow protrusion is formed on an outer peripheral wall of the bent section substantially in parallel to a longitudinal center line of the straight section. The protrusion has an opening formed in one of opposed ends thereof which communicates with inside the bent section. The additive injector is designed to produce a cone-shaped spray of additive and installed on the other end of the protrusion to inject the cone-shaped spray of additive into the exhaust pipe without interfering with at least a downstream edge of the opening.

  • Patent number: 7347188
    Abstract: In a common rail fuel injection system, a fuel pump pressure-feeds fuel to a common rail, which accumulates the fuel at high pressure corresponding to fuel injection pressure. An electronic control unit (ECU) drives and controls a suction control valve provided in the fuel pump to regulate a pressure-feeding amount of the fuel and to perform fuel pressure feedback control. The ECU calculates a differential term of a control amount of the suction control valve based on a pressure deviation of the fuel pressure in the common rail with respect to target pressure. The ECU sets the differential term at zero when the fuel pressure is higher than the target pressure and the differential term of the control amount is a value for pressure-feeding the fuel.

An insulation film is formed to extent on side surfaces of the ridge, on the inside of the grooves, and those portions of the contact layer which are located on the outside of the grooves. The thickness of those portions of the insulation film which are located on the contact layer in the areas on the outside of the grooves is set to be greater than at least the thickness of the electrode. Besides, a pad electrode is formed to cover the electrode and to extend on the insulation film on the upper side of the areas on the outside of the grooves. The upper surfaces of those portions of the pad electrode which are located on the upper side of the areas on the outside of the grooves are set to be above the upper surface of that portion of the pad electrode which is located on the upper side of the ridge.

  • Patent number: 5504499
    Abstract: After an initial starting single color may or may not be provided, the user may indicate a global sensation, such as morning, so that all colors inputted thereafter will be modified by the global sensation, or input a basic color, such as blue. In either case, menu driven user input information may include any number of human sensations relating to color for modifying the previously compounded color. In each case, the newly compounded color is displayed in a color display area on the screen. Thus formed, new colors may be named and stored to be retrieved at a later date. The menus on the display screen may be grouped according to basic decisions, basic colors, and compounding modifications according to human sensations, which latter may be subgrouped according to specific types of sensations such as mood, feeling, temperature, and the like.
