Title: Sense circuit of semiconductor memory
Inventor: HORIGUCHI SHINJI
IPC: H01L21/8242
Filed: 1987-09-04
Abstract: PURPOSE:To prevent a noise which is dependent on a data pattern by a method wherein a pair of MOS transistors constituting a sense amplifier own a source diffusion layer and an electric-current path from the source diffusion layer to a sense-amplifier drive signal wiring part jointly. CONSTITUTION:Two pairs of MOS transistors Q0 and Q1, Q2 and Q3 for a sense amplifier own a source diffusion layer jointly. Parasitic resistance exists in an electric-current path from the source diffusion layer to a second-layer Al region; this parasitic resistance is owned jointly by the two pairs of MOS transistors constituting one sense amplifier, and is separated from the electric- current path of the sense amplifier in an adjacent data line. Accordingly, an operation of a data line to be noticed is not influenced by a data which has been read out in the adjacent data line. In other words, it is possible to prevent a noise which is dependent on a data pattern according to this layout.

Abstract: PURPOSE:To fully use the converting dynamic range of a signal level by respectively outputting a signal upper limit value when a video signal reaches a saturation area at the time of photographing and the converting signal of an optical image when it does not reach the saturation area. CONSTITUTION:The optical images of respective colors passing through a lens system 1, an optical color separating system 2 are signal converted in image pickup parts 3R, 3B, 3G, a bias part is removed in detecting parts 4R, 4B, 4G, the video signals S4R-S4G and fed to saturation detecting parts 5R, 5B, 5G and amplifying parts 8R, 8B, 8G. In the respective detecting parts 5, the signals S4R-S4G are compared with reference signal levels S6R-S6G from a generating part 6 and when onto one of the signals S4 reaches the signal S6, corresponding bias changing control signals S5R-S5G are fed to a voltage generating part 7, consequently, the level of the signal S4 is made constant. In such a case, when one of respective signals S3R-S3G reaches the saturation area, the upper limit value of said signal is outputted and when the signal S3 does not reach the saturation area, the converting signal thereof is outputted.

IPC: H01S3/105
Filed: 1993-07-06
Abstract: PURPOSE:To take out full power from a laser tube using a single frequency by converting the beat frequency of spectra on the low and high frequency sides of a gas laser emitting three spectra into a voltage and controlling the length of resonator so that the beat frequency will be constant. CONSTITUTION:A laser light 1 emitting three spectra is detected by a detector 2 and converted into an electric signal having a first beat (between the central side and low frequency side) and a second beat (between the central side and the high frequency side). The IF output signal from a mixer 3 has a carrier frequency equal to the differential frequency between two beats and an oscillator 4 and an envelope equal to the differential frequency between two beats. The signal is then converted into an AC signal corresponding to the envelope through a rectifying/detecting circuit 5 and a low-pass filter 5 thus obtaining a third beat (between first and second beats) The third beat is converted through a frequency/voltage converter into a voltage which is then amplified through a power amplifier 8 and controlled so that the third beat has a constant frequency.

Abstract: PURPOSE: To enable a producer to sell egg packs in a shop, and to eliminate the removal of containers, by folding a loading shelf in such a way that an upper bent part is bent upward and a lower bent part is bent downward. CONSTITUTION: Egg pack T-positioning protrusions 3C for preventing egg packs from positionally deviating are projected from the upper surface of a loading shelf, at positions where the protrusions fitted in recesses of the egg packs T. An upper bent part 3A is located at a position forward of the rear end edge of the shelf 3, and an intermediate panel 3 inclined rearward, is folded into the upper stage loading shelf 3 without forwardly falling down. Accordingly, it does not hinder the loading of the egg packs T onto the lower stage shelf. The distance between the upper bent part 3A and the rear end edge is shorter than the overall length of the egg pack T. In the folded condition, a part of each of the egg packs T is projected forward from the rear panel 3, and accordingly, the egg packs T laid in the rear row can be taken out.  When all of the topmost stage egg packs are sold out, the loading shelf 3 is folded, and the front panel 3C is coupled to the intermediate panel 3 through the intermediary of a lower bent part 3B so that the height of the loading shelf 3 is lowered in the folded condition.
