摘要： A tape like material including synthetic resin for a filter element is bent into a corrugated pattern while the material is passed between pairs of forming and cutting rollers. Since pairs of cutters are provided within the rollers and since guide plates are provided around the rollers, the material is held abutting the rollers even when the material is cut by the cutters. The material is then conveyed within a reducing drum. The pitch of the corrugated portions formed on the material is reduced and the material is formed into a semicircular shape within the reducing drum. After passed the reducing drum, the material is transferred to a forming path. Since the forming path has an introducing portion having a semicircular sectional shape similar to that of the material leaving the reducing drum, an outlet portion having a circular sectional shape similar to that of the finished filter element and an intermediate portion having a sectional shape gradually varied from the shape of the introducing portion to the shape of the outlet portion, the material is shaped to a complete circle while the material travels along the forming path. A crystal type filter element is thus formed from a tape like material automatically.

摘要翻译： 包括用于过滤器元件的合成树脂的带状材料在材料在成形辊和切割辊之间通过时被弯曲成波纹状图案。 由于成对的切割器设置在辊内，并且由于在辊周围设置导向板，所以即使当切割器材料被切割时，材料也保持抵靠辊。 然后将材料在还原鼓内输送。 形成在材料上的波纹部分的间距减小，并且材料在还原滚筒内形成半圆形。 在通过还原鼓之后，将材料转移到成形路径上。 由于形成路径具有与离开还原鼓的材料类似的半圆形截面形状的引入部分，具有与完成的过滤元件类似的圆形截面形状的出口部分和具有逐渐变化的截面形状的中间部分 从引入部分的形状到出口部分的形状，材料成形为完整的圆形，同时材料沿着成形路径行进。 因此，由带状材料自动形成晶体型滤光元件。

摘要： A camera for shooting a movie picture and a still picture has a casing in which a pair of imaging optical systems for shooting a still picture and a movie picture, respectively are opened in a front surface of the casing. A functional section for shooting a still picture is disposed in the proximity of the imaging optical system for shooting a still picture, circuits and mechanisms necessary to shoot a movie picture are located in the rear side of the imaging optical system for shooting a movie picture, and a video tape recording mechanism and circuits related thereto are arranged at the back of the functional section for shooting a still picture. Consequently, a movie picture and a still picture can be shot at the same time. Since a film can be loaded in and removed from the camera through the upper surface of the casing, a statisfactory operability is attained. Furthermore, the casing is provided with a cap covering the upper surface of the casing and hence the casing has an improved strength and effectively prevents water and dust.

摘要： A composite camera apparatus employing a video camera device, a still camera device and a strobe device. The video camera device includes an electric circuit for picking up video data and processing the video data to record a video signal on a recording medium, such as a video tape. The electric circuit of the video camera apparatus includes means, associated with a strobe device and responsive to initiation of stroboscopic flashing, for controlling the electric circuit for recording the video signal so that a predetermined number of the video data picked-up at the occurrence of stroboscopic flashing, may not be reproduced when the video signal is reproduced by means of a VTR on a video monitor.

摘要： A fuel injection arrangement for a diesel engine. An overflow passage for high pressure fuel is provided in the engine's fuel injection pump. A solenoid valve is disposed in the overflow passage for controlling the fuel injection amount through its on-off operation. The time when the fuel injection pump starts injecting fuel is detected by an injection start detector. To this injection starting time point is added a target injection period to determine an injection end time. At this injection end time the solenoid valve is opened to discontinue the fuel injection. The target injection period is determined according to operating conditions of the engine. Since this apparatus detects the actual injection start point and controls the injection period on the basis of the result of the detection, the fuel injection amount can be controlled extremely accurately.

摘要： A distributor type fuel-injection pump according to the present invention is provided with a rotor which is rotated by an engine. The rotor has a pair of plungers slidable in the radial direction of the rotor, and a fuel pumping chamber is defined between the plungers. The rotor is surrounded by a cam ring which reciprocates the plungers as the rotor rotates, thereby sucking fuel into the fuel pumping chamber and pressurizing the fuel therein. The fuel pressurized in the fuel pumping chamber is distributed to individual cylinders of the engine. A plurality of spill holes are formed in the rotor, communicating with the fuel pumping chamber and opening to the outer peripheral surface of the rotor. A control sleeve to open and close the spill holes is axially slidably fitted on the rotor. First and second spill grooves capable of communicating with the spill holes are formed on the inner peripheral surface of the control sleeve. The first and second spill grooves open or close the spill holes to define the timing for the start of fuel delivery in the fuel pumping chamber and the timing for the end of fuel delivery, thereby determining the amount of fuel delivery.

摘要： The air-to-fuel ratio of a combustible mixture supplied to an engine is controlled by a feedback loop which includes an integration circuit for integrating the output signal of an oxygen sensor which detects the oxygen concentration in the exhaust gases of the engine, to produce an output voltage. The output of the sensor is applied to the integration circuit through a switch which opens in response to predetermined conditions of the engine whereby the output voltage of the integration circuit is held at a value occurring just before the switch opens.
