Filed: 1981-07-08
Abstract: PURPOSE:To use a counter circuit for the purpose of fail safe by constituting the counter by a shift register to easily detect the internal status. CONSTITUTION:In a shift register SR with parallel input terminals I1-In of N bits, parallel output terminals Q1-Qn of N bits and a series input terminal J, an input setting circuit IS sets up ''1'' only to the terminal I1 and ''0'' to terminals I2-In under a start signal ST of the L level. If the signal ST is turned to the H level and a count pulse CP is applied to a clock input terminal T, ''1'' is successively outputted from the terminal Q1 of the SR in accordance with the input of CP, the internal status of SR is successively shifted in the right direction and the outputs are inputted to a test circuit nC1. The circuit nC1 is constituted by an 1 out-of N bits test circuit and the complemental relation between the output terminals P, Q is maintained only when only one input is ''1''. Thus, whether the SR is correct or not can be tested by inputting the outputs P, Q to an exclusive OR circuit E-OR and supervising the H level of an output CH.

Title: Photoelectric conversion device
Inventor: TANAKA AKIMASA
IPC: H01L31/10
Filed: 1989-04-26
Abstract: PURPOSE:To increase detection sensitivity in ultraviolet rays region, and improve functions of spectrum detection and the like by optically shielding end-portions of a P-N junction surface from ultraviolet rays with a light shielding layer, fixing a light shielding layer at a specified potential with a wiring layer, and making a formed depletion region constant. CONSTITUTION:End-portions 15a of a P-N junction surface 15 constituted of a diffusion region 14 is covered with a polycrystalline Si layer 13, and optically shielded from ultraviolet rays, viewing from the light irradiation side. When a photosensitive region is irradiated with light, carrier is captured in a depletion region formed on a P-N junction surface 15, and photo output current flows in each photo diode. At this time, leak current in the photo diode mainly generates at end-portions of the P-N junction surface when ultraviolet rays are projected. Since the end-portions 15a are optically shielded with a polycrystalline Si layer 13, the increase of leak current is blocked. Further the layer 13 is electrically connected and grounded, so that electric charge is not stored in the layer 13. Hence the change of a depletion layer formed in the end-portion 15a can be restrained, and photodetection characteristics in ultraviolet rays band are stabilized.

Title: Mountain-climbing pickel
Inventor: ISHIOKA SHIGEO
IPC: B25D7/00
Filed: 1981-07-07
Abstract: PURPOSE:To increase a support force, by a method wherein a spit rope is  locked to one end of a spit hole in a spit pivotably positioned to a shaft, other end is located so that it can engage a climbing rope, and a slack is produced in the proximity of the center of a shaft. CONSTITUTION:In case a last slips down during mountaineering, a posture of a top 27 is assumed, a spit 1 of a pickel is driven in ice and snow surface, and a left hand is worked through a slack to grasp a shaft 2. When the last slips down, a pickel rope 43 runs downward following a time rope 27, and a lock ring 15 is dislocated to unreel a spit rope 45. When a spit rope 3 is stretched vertically against a plane of a drawing, a moment is applied to the spit 1 to turn the spit, a turn force is not exerted on the head of the pickel, and a support force is prevented from weakening. Additionally, the spit rope 3 is embedded in a longitudinal recess 14, and this prevents it from impeding.

IPC: G04C3/14
Filed: 1978-08-31
Abstract: PURPOSE:To provide an analog type electronic watch, which has a small loss for electric-mechanical energy convertion, by connecting a capacitor in parallel with the both terminals of the coil of a step motor. CONSTITUTION:A T type FF2 is inverted upon each reception of the pulses from an input terminal 1 so that pulses are generated from NAND circuits 3 and 5 in an alternate manner. These pulses are amplified in current by buffer circuits 4 and 6 and are alternately fed to the both terminals of a coil 8 and a capacitor 7. If, at this time, the pulse width for the step motor drive is denoted at To, the capacity C of the capacitor 7 is set such that the tuning by the capacitor 7 and the coil 8 is accomplished in accordance with the righthand Equation (wherein: Lo stands for the inductance of the coil 8; and Co stands for the floating capacity). Thus, the drive pulses can be highly efficiently transmitted to the coil 8 and converted into a mechanical energy.

Title: Hot iron desulfurizing method in vessel
Inventor: TAKEMURA YOUZOU
IPC: C21C1/02
Filed: 1977-09-06
Abstract: PURPOSE:To prevent resulfurization of hot iron due to desulfurization slag in desulfurization of hot iron in a torpedo car adding a result furization inhibitor in advance. CONSTITUTION:To hot iron in a torpedo car is added quick lime or dolomite as a resulfurization inhibitor in an amt. of 1-3kg/t of hot iron to increase the basicity of slag in the car. Next CaC2 powder or the like is blown into the bot iron to desulfurize it. Because of the high basicity, CaS is sticked to CaO particles in desulfurization slag of the temp. of the hot iron, resulting in no resulfurization. When the desulfurized iron is discharged from the car and fresh hot iron is charged from a blast furnace, blast furnace slag of low basicity and low m.p. contacts with the residual desulfurization slag to be prevented from dissolution in the car. Thus, resulfurization of hot iron due to desulfurization slag can be prevented.
