Title: Photographic device
Inventor: YOSHIDA HAJIME
IPC: G03B15/02
Filed: 1989-02-17
Abstract: PURPOSE:To prevent the picture in a see-through hole from being photographed while being overlapped with the picture of an object by fitting a member such as a half mirror, which possesses a light reflecting rate almost the same as a light diffuse-reflecting plate and can transmit light, in the see through hole of the light diffusion-reflection plate, and taking the picture of the object. CONSTITUTION:The member 8 such as the half mirror possesses the light reflectivity almost the same as the light diffusion-reflection plate 4 and can transmit light, and it is fitted in, adhered and provided on the see through hole of the light diffusion-reflection plate 4. Light from a light source 3 is made incident on the lower surface 4B of the light diffusion-reflection plate 4 from downward, and the object, which is positioned below the light diffusion-reflection plate 4, is irradiated by the reflecting light. In this time, the reflecting light quantity is almost the same between the reflecting light reflected on the lower surface 4B of the light diffusion-reflection plate 4 and that reflected on the lower surface 8B of the member 8. Thus, when the picture of the object is taken through the see through hole 5, the image of the see through hole 5 is scarecely overlapped with the picture of the object and photographed.

Abstract: PURPOSE:To allow an upper layer part of a gate electrode having a T-shaped form to be formed to the desired thickness; besides, to allow this device not to do damage to a semiconductor substrate when it is formed by forming an upper layer metal of the gate electrode having the T-shaped form with a plating technique. CONSTITUTION:After an opening is formed at an insulating film, the whole plane of the first metal layer 4 including the inside of the opening is vaporized and in such a case, the first metal layer 4 is thickly vaporized to some extent, because its layer is also formed as a feeder electrode with a post-process plating technique. Then, an opening corresponding to an upper layer part of the T-shaped gate electrode is formed. Using the first metal layer 4 that is exposed to an opening part of a resist 5 as the feeder electrode, the second metal layer is formed with the plating technique on the above first metal layer 4. In such a case, the first metal layer may be formed to the desired thickness that is thicker than that of the resist 5. Finally, after removing the resist 5, an unnecessary metal layer 4 is removed by etching with the second metal layer 6 as a mask and then the desired T-shaped gate electrode is formed.

Title: Phase difference absorbing circuit of digital signal
Inventor: SHIROTA NORIHISA
IPC: H04L7/04
Filed: 1985-02-27
Abstract: PURPOSE:To prevent a circuit scale from being increased by connecting plural sets of latches and gate circuits in cascade and controlling the gate circuits so as to turn off a corresponding latch among the plural latches in latching operation thereby absorbing the phase difference of a digital signal without using a memory. CONSTITUTION:An output control signal fed from a shift register 27 to a gate circuit 24 is extracted at an output terminal 29 shown in SROT via a latch circuit 28. The output data of gate circuits 23-26 is fed to a latch 22 and latched sequentially by using an internal clock CKR. The output data is extracted at an output terminal 21 shown in DATA from the latch 22. It is required to avoid the period when a latch is latched corresponding to each gate circuit while each of the gate circuits 23-26 is turned. That is, it is to prevent the latch 22 to receive the data on the way of the change and when, e.g., a latch 3 is latched, it is controlled that the timewise remotest gate circuit 25 is turned on.

Abstract: PURPOSE:To decide conforming and nonconforming articles speedily with simple constitution by using a ROM to convert a digital output from a counter circuit corresponding to the output signal of an IC into conformable and nonconformable article data. CONSTITUTION:An oscillation circuit 2 outputs clock pulses CL at any time and an AND gate 3 conducts only in a period T wherein a pulse signal PS is outputted, so that the frequency of its output signal S1 becomes equal to that of the pulses CL. Then, a counter circuit 4 counts the signal S1 and then outputs a signal S2 corresponding to its counted value when finishing counting the final pulse of the signal S1. This signal S2 corresponds to its digital value and specifies an address of the ROM 6. The digital value of the signal S2 is smaller than a specific value, data D1 indicating a conformable article is outputted according to the address of the ROM 6 where it is stored and when the digital value is larger than the specific value, data D2 indicating a nonconformable article is outputted. Further, a DC tester outputs a signal indicating whether the IC 1 is normal or not according to whether the input signal from the ROM 6 is 'L' or 'H'.
