Abstract: PURPOSE:To enable a laser beam on a sample to be condensed to a small size via a concave reflecting mirror with a large numerical aperture (NA) by providing a laser mass spectrometer with the mirror above an electrode or the like to accelerate or deflect ions. CONSTITUTION:A laser beam 7a from a laser beam source 6 is converged on a sample 2 through a concave reflecting mirror 45, and a laser beam 7b from another laser beam source 6b is converged on the center of the sample 2 through an objective lens 22b. An ion beam 21b thus excited comes to be incident on a mass analysis section 1 and reflected with an ion reflector 30. Then, the ion beam 21b enters an ion detector 34. Ion mass is analyzed on the basis of an ion flight time. In this device, the concave reflecting mirror 45 is fitted above a ripeller electrode 28a to accelerate or deflect ions, and there is no other obstacle than the electrode 28a among the mirror 45, the lens 22b and the sample 2. The mirror 4 and lens 22b, therefore, can be made to have a large numerical aperture with a small focal distance, and the laser beam 7a on the sample 2 can be condensed to a small size. A similar effect can be obtained by providing the mirror 45 under the electrode 28a.

Title: Electronically controlled fuel injector
Inventor: NORIMATSU HIDEAKI
IPC: F02D41/34
Filed: 1978-03-02
Abstract: PURPOSE: To optimize accelerating fuel necessary for an engine and improve the feeling of ride, by generating an accelerating pulse signal in the acceleration of the engine and controlling the time width of the pulse signal depending on the rotational frequency of the engine.  
     CONSTITUTION: An F-V conversion circuit 10 generates an output depending on the revolution of the engine. An output is picked out from a throttle switch 9. These outputs are entered into a pulse generator circuit 12, which generates an accelerating pulse at the time of such acceleration of the engine that a throttle valve 9a entirely closed is opened. The pulse is entered into an OR circuit 6 to open a fuel injection valve 8 non-synchronously with the revolution of the engine to supply the accelerating fuel to the engine. When the pulse generator circuit 12 is at an F-point, the throttle valve 9a is closed for more than a predetermined time. Only when the throttle valve is opened after that, the pulse is produced. The time width of the pulse depends on the rotational frequency of the engine.

Title: Recording device and reproducing device
Inventor: KATO SHIRO
IPC: G11B20/10
Filed: 1989-02-02
Abstract: PURPOSE:To attain the continuous recording operations with no interruption caused by the exchange of recording media by using a recording medium and a buffer memory. CONSTITUTION:The input signals obtained within an exchange period of a recording medium 104 are stored in a buffer memory 102 and never lost. At the same time, the signals are read out of the memory 102 and recorded at a rate higher than the input of the memory 102, i.e., at a high speed until the prescribed number of idle areas are secured in the memory 102 after the exchange of the medium 104 is through. Thus it is possible to avoid such an inconvenient case where the memory 102 is overflowed and the signals to be recorded are partly lost. As a result, the signals to be recorded can be continuously recorded with no interruption despite the exchange of the medium 104.
