IPC: G01N29/44
Filed: 1981-03-30
Abstract: PURPOSE:To make it possible to confirm and correct in a short time and for sure a distance amplitude correction curve that has been made by shifting from calibration mode to actual defect finding mode everytime most appropriate control value for each length of route is obtained. CONSTITUTION:In a calibration mode, a probe 1 is placed on a specimen 2 for calibration, and the echo of an artificial defect 3 is displayed on A scope 6. The level of the height of echo required on A scope 6 is set at a standard level and defect echo is made to reach the level by adjusting the amplification factor of an amplifier 5. Then the route lengths are input to a control circuit from a route length counter by means of a micro computer. The input route length values and control values are added to the data, and interpolation is calculated. By this arrangement the confirmation and correction of distance amplitude correction curve becomes accurate and short in time.

Title: Data readout system for semiconductor storage element
Inventor: SAITO TAKUMI
IPC: G11C11/401
Filed: 1989-02-27
Abstract: PURPOSE:To perform readout at high speed by providing a circuit to hold data equivalent to the number of bits read out simultaneously of a storage element by the timing of a column address strobe signal, and obtaining readout data at every change of the level of the strobe signal. CONSTITUTION:The data of four bits is inputted to a selector 7 via a latch circuit 10, and first data d 1 is selected by a selector control circuit 11, which goes to a data output signal. Next, when the column address strobe signal CAS 5 changes from a low level to a high level, a latch timing signal 12 is outputted from a clock generation circuit 6, and the content of the latch circuit 10 is fixed. Simultaneously, an instruction to output second data d 2 is issued from the selector control circuit 11 to the selector 7, and a signal is outputted from the selector 7 as the data output signal. Similarly, the selector control circuit 11 switches the output of the selector 7 even when the CAS 5 changes from the high level to the low level, or from the low level to the high level. Thereby, it is possible to remarkably shorten processing time than ever before.

Title: Multi-direction multiplex communication system
Inventor: NIINA SABURO
IPC: H04B7/26
Filed: 1990-02-27
Abstract: PURPOSE:To prevent a transmission efficiency from being deteriorated even when the frame period is reduced by applying multiprocessing to a radio frame, making an additional bit transmission channel independent attended to each communication channel and sending an additional bit transmission signal for each talking channel in the unit of multi-frame. CONSTITUTION:A radio frame is formed to be a unit frame comprising a synchronizing signal Fi, a call connection control signal C channel, talking channels CH1-CHN and one additional bit transmission channel HKi. The signal Fi is of multi-frame structure in which unit frame time is T' and a period is N. As a result, additional bit transmission channels HK1-HKN for the talking channels CH1-CHN in the N multiframe period are ensured. Through the constitution above, since one additional bit transmission channel only is provided to N-set of the talking channels CH1-CHN from the standpoint of the unit frame, the transmission efficiency in the talking channel is improved.

Abstract: PURPOSE:To have high sensitivity and high resolution by forming a light-guiding window for irradiating light from a light source on a detected object in the centers of the respective sensor devices. CONSTITUTION:Light applied to the respective sensor parts 11 from a source of light is transmitted through a first light-guiding window 14 formed on a light-shielding layer 13 and a second light-guiding window 17 formed on a channel region 16a of a silicon thin film layer 16 and is applied to source document 30. Further, the light-shielding layer 13 is not formed between the sensor parts 11, 11 so that light goes through also this part for being irradiated on the source document 30. Then, the light is irregularly reflected by the source document 30 while reflected light reflected in the direction shown by an arrow is incident on the channel regions 16a of the respective sensor parts 11. Of the reflected light to be incident on the channel regions 16a, the reflected light of the light transmitted the first and second light-guiding windows 14, 17 has a small angle of reflection on the surface of the source document 30 and a short optical path length because the second light-guiding window 17 is formed about in the central part of the channel region 16a. Accordingly, the reflected light incident on the channel region 16a has large intensity of light.
