Title: Compound type digital electric shutter facilitating operation for iris correction
Inventor: NOBUSAWA TSUKUMO
IPC: G03B7/093
Filed: 1978-08-29
Abstract: PURPOSE: To realize easy and correct operation for iris correction, by operating the light response shutter speed reset device when the light is proper, and operating the slow speed or high speed fixed shutter speed reset device after correcting the iris when the light is at low luminance or at high luminance.  
     CONSTITUTION: When the photographic light is proper, a pilot lamp L 2  lights up, and when the shutter is released after confirming this lighting, a light response shutter speed reset device M functions. When the photographic light is at low luminance and improper, lamp L 3  or L 4  lights up, and the photographer judges the degree of improperness from this lighting. By turning an adjusting ring 14a to open an iris F, correction of the iris can be known from extinction of the lamp. The shutter speed at this time is the same slow speed fixed shutter speed as when the slowest shutter is released by the light response shutter speed reset device M.

Title: Manufacture of semiconductor device
Inventor: TOKITOMO KAZUO
IPC: H01L21/8229
Filed: 1983-06-13
Abstract: PURPOSE:To prevent a pin-hole on a mask from being transferred onto a semiconductor substrate when a positioning mark is formed on the semiconductor substrate by patterning with two overlapped masks. CONSTITUTION:A buried layer 12 is formed in an Si substrate 11 and and SiO2 film 13 is formed on the surface of the substrate 11. In order to form a positioning mark by which a displacement after an epitaxial growth is detected on the substrate, an exposure is performed with two overlapped see-through masks 21 and 22. A center positioning window 21-1 is formed at the center of the mask 21 and positioning windows 21-2 are formed at the left and right prescribed parts of the mask 21 with a high accuracy. Positioning windows 22-1 are formed on the mask 22 at the positions corresponding to the positioning windows 21-2. The size of the windows 22-1 has allowance of ten to several dozen mm. over the size of the windows 21-2. If the exposure is performed with the overlapped masks like this, a probability of the coincidence of pin-holes is very little. Therefore, an unnecessary SiO2 film produced by a transfer of a pin-hole at the time of photoetching is not formed and the SiO2 film as a prescribed positioning mark 14 is selectively formed.

Title: Thermal recording printer
Inventor: OONO TADAYOSHI
IPC: B41J2/345
Filed: 1984-05-28
Abstract: PURPOSE:To arrange so that satisfactory printing may be performed even on PPC paper by providing thermal head heating elements of such size as smaller than the minimum image dot and forming the minimum image dot consisting of printing pixels obtained by the drive of heating elements. CONSTITUTION:In a printer capable of thermal transfer to recording paper 45 such as PPC paper through an ink ribbon 46 consisting of a heat-melting ink layer 47 and a base 48, a thermal head 41 has two heating elements 42, 42 which take care of the formation of the minimum image dots. In this way, the same temperature distribution as in a low speed drive can be obtained by the mutual interference of heating elements even in a high speed drive. Accordingly, the ink image dot 49 of such size as proximate to the minimum image dot can be obtained. For this reason, even recording paper having unsatisfactory smoothness such as PPC paper can be printed without missing or flawed image dots, thus providing the same print quality as in low speed printing even when high speed printing is performed.

Title: Automatic tracking system for calling subscriber
Inventor: MARUYAMA MINORU
IPC: H04Q3/00
Filed: 1980-08-05
Abstract: PURPOSE:To track a calling subscriber automatically even between different telephone exchanges by transferring information, which contains the number of a called subscriber and calling-subscriber tracking display, to a high-priority ladder repeater station and by making a comparison with the calling-party-subscriber's number of a calling subscriber. CONSTITUTION:When a person in charge of maintenance registers on a typewriter TYP the telephone number of a subscriber SUBB who is to track a calling subscriber, an exchange EL2 wherein the SUBB is equipped transmits the telephone number of the SUBB and a calling-subscriber tracking indication signal to a high- priority ladder repeater station ET. The repeater station ET registers the received information in a storage device MEM. As a subscriber SUBA sends a call signal, the CPU (CC2) of the repeater station ET makes a comparison between the telephone number of a party subscriber sent from an exchange EL1 and that of the SUBB stored in the device MEM. When the comparison result shows cnincidence, tracking operation is started and the repeater station ET requests the exchange station EL1 to send the calling-subscriber's number, thereby sending the stbscriber's number, of the SUBA to the exchange station EL2.
