Title: Semiconductor photodetector
Inventor: SENBA SHINJI
IPC: H01L31/107
Filed: 1991-02-14
Abstract: PURPOSE:To provide the title semiconductor photodetector capable of avoiding the deterioration in the photointensity and photocurrent as well as in the response rate. CONSTITUTION:A p type semiconductor region 4 wherein photodiffraction means 30 are arranged is further selectively arranged in an n type semiconductor substrate 2. Besides, the phototransmission layer of an n type semiconductor is laminated on the photoabsorption layer of the n type semiconductor and then a p type diffused region penetrating into the photoabsorption layer is selectively arranged in the phototransmission layer so as to be laminated on this p type diffused region and then the photodiffraction means 30 are arranged. Through these procedures, the photointensity in the central part of flux can be decreased to avoid the saturation of photocurrent so that the deterioration in the photointensity and the photocurrent as well as in the response rate may be avoided.

Title: Smut removal from mg alloy surface
Inventor: KAJIYAMA TAKASHI
IPC: C23G1/22
Filed: 1993-01-13
Abstract: PURPOSE:To remove the smut sticking to the surface of an Mg alloy after pickling without melting the Mg alloy. CONSTITUTION:This smut removal treating liquid for the Mg alloy is an aq. soln. prepd. by dissolving an alkaline salt of ethylenediaminetetraacetic acid at 5 to 120g/l and is more preferably adjusted to pH12 to 13 by addition of an alkali thereto. The Mg alloy to be subjected to smut removal is brought into contact with the smut removal treating liq. by immersing, spraying, etc. Since the smut removal is executed in a high pH region where Mg is passivated, the texture of the Mg alloy itself is not damaged. The treating liquid exhibits the higher detergency than the detergency of a treating liquid of a hydrofluoric acid system. Dense and homogeneous chemical conversion films, anodically oxidized films, etc., are formed in subsequent surface treatment stages on the Mg alloy from which the smut is removed.

Title: Dredging apparatus
Inventor: KIHARA MITSUO
IPC: E02F3/90
Filed: 1979-02-26
Abstract: PURPOSE: To automatically feed priming water of the dredging pump and the lubricating water of the cutter by conneting the discharge side of the water pump to the discharge side of the dredging pump through a check valve while the discharge side of the pump connected to the water pipe on the bearing of the cutter.  
     CONSTITUTION: When the water pump 18 is actuated, water discharge from the pump 18 is fed to the dredging pump 10 and the water pipeline 26 by way of a choke valve 34 and a check valve 35, and the same time, the water is fed to the water pipes 23 and 24, where it first reaches the sand discharging pipe 17 because of extremely small clearances 19a and 20a. Upon the driving of the dredging pump following the opening of the cock 30, the check valve is closed to stop the supply to the sand discharging pipe 17 and the water from the water pump 18 is sent to the water pipes 23 and 24. Upon the halting of the dredging pump 10, the check valve 35 is opened to allow the priming water automatically to be sent the dredging pump 10 and the water pipeline 26 from the water pump 18.

Title: Lighting device for underground space
Inventor: HARADA NORIMASA
IPC: F21S2/00
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the degree that residents underground feel uneasy mentally and physically so as to ensure a comfortable life by disposing in an underground space an illuminating orbit curved into an arc, and moving a light source as the sun moves during the day, which the light source is capable of adjusting its color temperatures and total light flux. CONSTITUTION:An illuminating orbit 2 curved into an arc is disposed in an underground space 1 and in addition to a main light source, a light source 4 capable of adjusting its color temperatures and total light flux is mounted to the illuminating orbit in such a manner as being freely moved and is moved as the sun moves during the day, to perform variation of light of the morning, day and night above ground. The performance of variation of light of the morning, day and night can be obtained by varying the ratio of the light flux of e.g. a high pressure sodium lamp of color temperature 2,500[K] to that of a metal halide lamp of color temperature 6,500[K]. The degree that residents feel uneasy mentally and physically is thereby reduced and they can live a comfortable and secure life.

Title: Method to restrain increase in propelling resistance
Inventor: HONMA RYOJI
IPC: E21D9/06
Filed: 1995-01-13
Abstract: PURPOSE: To facilitate long-term propelling work over a long distance by using a low water flow propelling pipe, and filling a plastic material mainly composed of clay and water in a clearance between the propelling pipe and the ground. CONSTITUTION: A plastic material is injected so that the plastic material fills up a tail void up to all the corners, and the fact that it is sufficiently filled up to a clearance can be known by observation of suddenly increasing injection pressure. In this case, after the plastic material is injected into the tail void from a front injection port, the plastic material is injected into the tail void from a small hole of a succeeding propelling pipe in a position slightly separate from this injection port. When injection is possible, it is judged that a void remins on the outer periphery of the propelling pipe, and the plastic material is further injected from its small hole, and press-in is continued until the injection pressure can stand against earth pressure outside of the propelling pipe.  Therefore, the propelling pipe is propelled by maintaining it in a condition of floating in the plastic material, and propelling resistance is reduced, and propulsion is facilitated.

Filed: 1992-02-06
Abstract: PURPOSE:To attain an excellent reproduction picture by using a block processing means processing component picture data so that the border of blocks is not overlapped thereby dispersing block distortion even when the block distortion takes place in plural data of a same area. CONSTITUTION:A block processing circuit 11 forms a block so that the border of blocks is not overlapped between component data and the block is outputted to a DCT circuit 12. Then discrete cosine transformation is applied to each block and the result is outputted to an adaptive quantizer 13, in which the result is quantized adaptively. Then additional information comprising a quantization index, classification information and bit pattern selection information is outputted. The output data are recorded on a recording medium 14 such as a magnetic tape and a magnetic disk. Furthermore, the output data are subject to error correction coding or transmission line coding before the recording and transmission.

Title: Aperture blade driving device
Inventor: TANAKA KOUJI
IPC: G03B9/06
Filed: 1981-02-16
Abstract: PURPOSE:To control the reciprocating motion of a blade with the device of a simple operation, by linking a stopping-down member to a cam member, which has a gently inclined cam for stopping-down and a steeply inclined cam for opening reset, in a pulse-driven stop device. CONSTITUTION:An aperture blade 13 is held between a blade seat 3 and a crysanthemum-shaped metal fixture 2. An intermediate lever 1 intermediates between the crysanthemum-shaped metal fixture 2 and a driving cam 5. The cam 5 and a gear 18 is in one body; and when an actuator 17 of an electromagnetic driving device 16 is reciprocated once by a pulse, the gear is turned by a quantity corresponding to one frame. A pin 8 of the intermediate lever is energized to be brought into contact with the cam surface; and when the lever is turned by the rotation of the cam , the crysanthemum-shaped metal fixture is turned reciprocatively to open and close the stop. Since the opening is controlled by a pulse number and the electromagnetic driving device repeats the same operation in opening as well as closing operations, the mechanism and the control means are simplified.
