Title: Charge-coupled type semiconductor device
Inventor: FUJII ICHIRO
IPC: H01L29/762
Filed: 1985-06-21
Abstract: PURPOSE:To reduce dark current, by applying treatment, by which interface levels that are present at an interface between a semiconductor layer and an insulating layer are decreased, at a part of the interface. CONSTITUTION:On a silicon substrate 1, an SiO2 film 2 as an insulating layer is formed. Impurity doped low-resistance polysilicon layer 3 is further deposited. The polysilicon layer is patterned in a stripe shape by photoetching, and a transfer electrode is machined. At this time, many interface levels are yielded at the entire interface between the silicon substrate 1 and the SiO2 film 2. After the formation of a CCD circuit, a silicon nitride film 4 is deposited. Thus the interface levels are reduced to a large extent. After the treatment of reducing the interface levels with plasma nitride, the silicon nitride film 4 is removed by etching. The interface levels of Si-SiO2 are decreased to less than one half. Thus dark current can be reduced to a large extent.

Abstract: PURPOSE:To reduce the load of operation, to shorten operating time, to check misinputs, and to improve processing speed by making it possible to set up the display format of a display means at the retrieval of a KANJI (Chinese character) retrieving means and the display of the stored contents of a storage means. CONSTITUTION:At the selective display of a KANJI converted from KANA (Japanese syllabary) through a KANA key K1, a KANJI selection key K2, KANA-KANJI conversion key K3, a RAM, etc., an 1/2-column display key K4 selects 1-column display of 2-column display. In this case, a display step automatic/manual switch K5 selects automatic display or manual display corresponding to the setting of the switch K4. Since the 2-column display or 1-column display can be selected only by the switch at the selective display of a KANJI converted from KANA, layout information can be optionally set up. Consequently, the operating load of the operator can be reduced, the operating time can be shortened, misinputs can be checked and the processing speed can be improved.

Title: Heat-transmitting pipe and manufacture thereof
Inventor: NOSETANI KIYOSHI
IPC: F28F1/42
Filed: 1983-07-27
Abstract: PURPOSE:To effectively enhance the coefficient of heat transfer at the inside surface of a pipe, by arranging inside surface projections in a spiral form to induce turbulent flows in a flow of a fluid. CONSTITUTION:A plurality of inside surface projections 6 are provided on the inside surface of the pipe in a spiral form, so that turbulent flows are induced when a heat-transmitting fluid passes over the projections 6. In addition, the flow of the fluid in the axial direction of the pipe along the inside surface of the pipe is divided into left and right portions by each of the projections 6. Further, a spiral flow effect on the fluid flowing near the inside surface of the pipe is also produced by the spiral arrangement of the projections, resulting in complicate and delicate turbulent flows on the inside surface of the pipe. Accordingly, a boundary film liable to be formed in proximity to the inside surface of the pipe is effectively broken, and the coefficient of heat transfer at the inside surface is effectively enhanced.
