The optical element (3) may for example be an optical grating of the absorption, phase or reflection type or intermediate forms, a birefringent element, a Bragg cell, a combination of a totally reflective surface and a beam splitter or possibly a glass plate having one of its surfaces coated with a totally reflective material. The apparatus comprises a source for electromagnetic radiation (1), a detector (4) for receiving radiation scattered from particles in a sample volume (2), means for recording the output signals from the detector (4) and an optical element (3) of the above-mentioned type defining the position of a relevant particle pair.

Abstract: PURPOSE:To simplify the character segmentation processing of one character unit by symbolizing an input image to the direction line element of a minute area, extracting and eliminating a straight line portion which requires no recognition, and generating the histogram of the direction line element in a character part. CONSTITUTION:The character of an image input means 1 is symbolized to the direction line element of a local area and stored in a line element storage part 3, and thereafter, stored as the line element histogram in a line element histogram storage part 5.

Filed: 1980-05-09
Abstract: PURPOSE:To accomplish a clear printing with elimination of ghost generated at a high humidity by applying a control voltage comprising several pulse voltages corresponding to a record voltage of a fixed pulse width applied on a recording needle simultaneously. CONSTITUTION:A control voltage to be applied on a controlling electrode C is divided into several pulses so that the difference in the time constant may be utilized effectively at the charging or discharging of a voltage induced when the control voltage thus divided is applied. A counter C2 for obtaining an input signal of a decoder D is activated with an output signal divided by 1/n of a counter C1 to form an OR signal of the output from adjacent recorders through gates G52-G55. Then, the signal Si thus formed is inputted into 2-pulse generators P1-P5 to generate two pulses. The two pulses drive driving circuits A31-A35 to divide the pulse width of the convensional controlling voltage so that a controlling voltage waveform of two pulses is made at a pause equivalent to one-third as large as one pulse width.

Title: Gas laser device
Inventor: OOHASHI TSUNEYOSHI
IPC: H01S3/03
Filed: 1984-03-30
Abstract: PURPOSE:To prevent the deviation of glow discharge due to the electrification of the discharge part by a method wherein a plurality of ringlike conductive parts are provided by insulation from one another along the inner periphery of a discharge tube. CONSTITUTION:Conductive parts 13 are provided ringlike along the inner periphery of the discharge tube 3 and supported by the discharge tube 3 which is an insulator, each of which parts is insulated from one another. Thereby, the conductive parts 13 become electrified by the glow discharge 7 in a gas flow; however, they become electrified uniformly ringlike because of the conductivity of the conductive parts 13. As a result, glow discharge generates inside the conductive parts 13 coaxially with the discharge tube in axial symmetry, causing no deviation such as the electrification of the discharge tube 3. Since the glow discharge 7 separates away from the discharge tube 3 by providing the conductive parts 13, the electrification of the discharge tube 3 can be prevented.

IPC: G04G13/02
Filed: 1981-04-22
Abstract: PURPOSE:To greatly reduce the setting procedure for the alarm time, by storing temporarily the alarm time having a high using frequency in correspondence to the switch. CONSTITUTION:For setting of the alarm time, either one of switches S1-SN is operated. Thus the time stored in an alarm time storing RAM M1 corresponding to the switch S1 is stored into an alarm counter 1. This time is compared with the present time through a comparator 2, and an alarm is generated when the coincidence is obtained. For the writing, the timepiece is set in the alarm correction mode to correct the alarm time by means of an external switch, and a memory/set switch is operated to operate either one of the switches S1-SN. As a result, the corrected alarm time is written into the RAMs M1- MN corresonding to the operated switch. In such way, the setting procedure can be greatly reduced for the subsequent alarm time.

Abstract: PURPOSE:To make the filling amt. of a molding material constant by separately operating cutting punches with respect to a plurality of cavities when the resin material is injected into a plurality of the cavities and central holes are punched in molded disks by the cutting punches. CONSTITUTION:Four example, in the case of two cavities, the resin injected from an injection device 3 is divided by a runner block 7 to be injected in cavities 6a, 6b. At this time, by the irregularity in a process manufacturing the runner block 7 or cavities 6a, 6b, a difference is generated between the filling degrees of the resin to the cavities 6a, 6b. In order to reduce this difference, cutting punch driving devices 11a, 11b are controlled so that a time lag is provided between the operations of both devices. In the case of four cavities, cutting punches may be individually driven and, when the division of the resin is stable, the cutting punches may be thrown into two together, to be driven by two drive means.
