Title: Measuring method of auger electron spectral spectra
Inventor: TORIKAI TOSHITAKA
IPC: G01N23/227
Filed: 1978-01-19
Abstract: PURPOSE:To prevent stray electrons from being modulated by applying micro- modulating voltage to the sample and modulating the secondary electrons released. CONSTITUTION:Only the DC sweep voltage is applied to a circular mirror type energy analyzer (CMA)5 and only the micro-cmodulating voltage is applied to the sample 4. Hence, when the electron beam from the primary electron radiation system 3 enters the specimen, only the secondary electrons released from the sample 4 are modulated and the stray electrons released from an iron pump 2, the opening part mesh 12 of CMA 5, etc. are not modulated. As a result, the measurement of electron spectral spectra may be performed with good S/N by the secondary  electrons only from the measuring region of the sample 4 equal to the diameter of the primary electron beam by the lock-in amplifier 7 which detects only the modulated electrons.

IPC: B41J29/38
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a printing processing apparatus capagble of printing printing data containing complicated figure drawing command without deteriorating quality. SOLUTION: Printing data described by a predetermined drawing command is converted to intermediate data of the max. extraction degree by an intermediate data forming means 1 and, on the basis of the intermediate data, a processing time estimating means 4 estimates the conversion time when an intermediate data converting means 2 converts this intermediate data to intermediate data lower in extraction degree and the developing time when a developing processing means 3 develops the intermediate data of each extraction degree and the intermediate data converting means 2 determines the extraction degree of the intermediate data to be converted and the speed of a speed variable image output means 5.  By this constitution, the intermediate data converting means 2 converts the intermediate data on the basis of the extraction degree and the developing processing means 3 develops the converted data on printing data and this data is outputted at a predetermined speed by the speed variable image output means 5. Since printing is processed only by changing the extraction degree of the intermediate data, high speed printing is enabled without deteriorating image quality.

Title: Solid oscillation device
Inventor: SEKINO TOSHIAKI
IPC: H03K3/357
Filed: 1981-01-16
Abstract: PURPOSE:To reduce the expansion of an oscillation frequency by removing a front part from each intermittent oscillation signal, obtained from an intermittently driven oscillation element, to prescribed time width, and using the remainder as an oscillation output. CONSTITUTION:A main pulse generator 6 generates pulses with pulse width Tw1 and a repetitive period Tr1, and this pulse signal is inputted to a pulse driver 7. The driver 7 generates a signal whose voltage level is inverted in polarity at the period of said pulse signal, and the signal is supplied to a PIN diode 2. The diode 2 operates so that a microwave circuit is turned off. The output of the main pulse generator 6 serves as a trigger signal for a pulse generator 9. The pulse generator 9 generates pulses with pulse width Tw2 to drive an IMPATT diode 1 with the pulse current. Said Tw2 is longer than the Tw1  and the pulse output of the driver 7 rises t1 seconds earlier than the pulse output of a driver 10. In this case a pulse microwave having pulse width (Tw2-Tw1+t1) and a repetitive frequency Tr appears at an output terminal 5.

Abstract: PURPOSE:To allow another host to make access to a disk device by enabling the release of the reserved state of the disk device when a host reserved with the disk device is hung up. CONSTITUTION:A disk controller (#1) 9 receiving a reservation command to a disk device (#1) 12 from a host (#2) 4 rejects the reservation request when the disk device (#1) 12 is assigned to a host (#1) 3. As long as the disk controller (#1) 9 reserves the disk device even when the command not accepted, it transmits a response confirmation command to the host (#1) 3 issuing the reservation command at specified interval and when there is no response, releases the reserving state of the disk device (#1) 12. Thus, access from the other host is avairable.

Title: Speaker driving system
Inventor: KAWAMURA SHINICHIROU
IPC: H04R3/04
Filed: 1980-01-23
Abstract: PURPOSE: To obtain a flat frequency characteristic for a constant current driving of a speaker, by giving a selective control of frequency to the input signal.  
     CONSTITUTION: The constant voltage source 20 is connected to the constant current amplifier 21 via the suppresion circuits 11∼15, and the speaker 22 receives a constant current drive via the amplfier 21. In this case, the mechanical impedance of the speaker 22 becomes extremely small at the area near the minimum resonance frequency and thus the energy radiated from other frequencies increases excessively. However, a flat frequency characteristics is obtained by inserting the circuits 11∼15 in front of the amplifier 21 to suppress the input signal in a selective frequency mode.
