Title: Production of flat pipe provided with inner fins
Inventor: WATANABE SHIYOUICHI
IPC: B21C37/22
Filed: 1984-05-22
Abstract: PURPOSE:To produce a flat pipe provided with inner fins at a low cost with good productivity by joining the lower edge part of vertical belt-like fins having a corrugated cross section to a belt-like metallic sheet and enclosing the fins with the metallic sheet thereby forming the flat pipe. CONSTITUTION:A belt-like fin material 12 is passed between forming rolls 14 and 15 to form the fins 2 having the corrugated cross section and the lower edge part 2a thereof is joined to the central part P of the horizontal belt-like metallic sheet 11. The sheet 11 is then bent from the part P to form a circular pipe 13. Both side edges 11a, 11b of the sheet 11 and the upper edge 2b of the fins 2 are integrally joined. Both side walls 13a, 13b of the pipe 13 are further pressed around the fins 2 toward the fins 2 to flatten the pipe and at the same time the fins 2 are stretched to increase the pitch of the corrugations. The flat pipe 1 provided with the inner fins 2 is thus formed.

Abstract: PURPOSE:To shorten the time required for printing and to allow efficient printing by reading out the data of a memory means in accordance with a print command signal and controlling an exposure. CONSTITUTION:A feed control means 102 monitors the film feed position just before a target image on approaching of this image and outputs a data taking in signal to a memory means 108 when the projecting light of a region for detecting the exposure of the target image is made incident on a line sensor 78. A memory means 108 determines the exposure from the output of the line sensor 78 based on this signal, takes in the data on the correct exposure and stores the same. Namely, this data is read out and the exposure is controlled when the print command signal is inputted and, therefore, the need for moving the line sensor after waiting for a film to stop in order to detect the exposure is eliminated. The efficiency of the printing operation is enhanced in this way.

Title: Formation of fine pattern
Inventor: YAMASHITA KAZUHIRO
IPC: H01L21/027
Filed: 1987-04-28
Abstract: PURPOSE:To contrive improvement in the contrast of a resist pattern by a method wherein ions are made to irradiate on the surface of the resist before conducting a reduction projection exposure or an electron beam exposure on the resist coated on the surface of a semiconductor wafer. CONSTITUTION:When photoresists 1 and 2 are spin-coated on a semiconductor substrate 3 and a collective irradiation is conducted using an irradiation device, the H-ions higher in concentration than that of the upper part 1 are applied to the lower part 2 of the resist. Then, when a photosensitive part 4 is formed by conducting an exposing operation using a reduction projecting and exposing device, a tapered latent image is grown. Subsequently, when the exposed part 4 is removed by a developing solution, the resist is removed from the surface of the resist in the beginning of the developing, and the developing operation makes progress while showing a trapezoidal shape. When the H-ions reach the highly applied part 2, the development in the lateral direction makes progress on the irradiation amount of the H-ions, and a resist pattern having an almost vertical cross-section shape is formed. As a result, the taper-shaped latent image is corrected, and the resist pattern having excellent contrast can be formed.

Title: Method for forming error correction code
IPC: G11B20/12
Filed: 1992-03-31
Abstract: PURPOSE:To enhance the capability by creating an error correction code for one or more of unit data as one unit and preventing those codes from adjoining each other in the radial direction on adjacent tracks, when unit data of a predetermined data amount is recorded on a recording medium by a plurality of units per track. CONSTITUTION:A plurality of tracks on a disc are divided at intervals of m tracks, one of which is used as an error correction track. That is, tracks No. a to No. (a+m-2) are used as information tracks TS, and a track No. (a+m-l) is used as an error correction track TC. However, the data in the adjacent sectors of the same sector number are not contained in one parity generation system, and thus, if a two-dimensional error occurs on the disc and errors are produced in the data of the same sector number on adjacent tracks, it is possible to correct the adjacent errors for the same sector number because the parity generation systems containing the errors are different.

Title: Video signal reproduction circuit
Inventor: IIZUKA HIROSHI
IPC: H04N9/45
Filed: 1995-04-28
Abstract: PURPOSE: To reduce the number of components by restoring a phase of a low frequency conversion color signal before frequency conversion. CONSTITUTION: A color signal from an input terminal 1 is extracted by an LPF 2 and given to an ACC circuit 3, in which the level is adjusted. The color signal with the adjusted level is fed to a phase restoration circuit 18, in which phase rotation applied at recording is restored. Thus, the circuit 18 restores the phase before the frequency of a low frequency conversion color signal is converted. Thus, it is not required to restore the phase in a frequency conversion circuit 19 and an output signal of a VCO 22 oscillating a prescribed frequency is applied directly to the circuit 19 through only the frequency conversion at single frequency.  The color signal converted into a prescribed frequency is extracted from a BPF 5 and fed to a burst extract circuit 8, only the burst signal is extracted and the phase is compared with a phase of an oscillated output signal of a stationary oscillation circuit 10 at a phase comparator 20. Then a comparison error voltage is applied to the VCO 22, in which the oscillated frequency is controlled.

Title: Instantaneous rotational speed detecting method for motor
Inventor: FUJITA KOETSU
IPC: H02P29/00
Filed: 1990-04-23
Abstract: PURPOSE:To reduce estimation error and to improve detection accuracy of the instantaneous rotational speed of a motor by making the interval between some sampling timing and following sampling timing variable and then employing the variable time interval in an estimator for estimating a disturbance torque. CONSTITUTION:When the interval of incoming pulse from an encoder l employed in the detection of the rotational speed of a motor is close to the sampling interval of a controller or when it is longer than the sampling timing, the time interval between some sampling timing and following sampling timing is considered as a variable which is then employed in an estimator 8 for estimating a disturbance torque according to a status formula of dispersion system of variable sampling time. Consequently, the disturbance torque can be estimated correctly even under low speed operation where the interval of the encoder pulse is longer than the sampling interval of the controller. By such arrangement, a speed detector exhibiting high accuracy upto a quite low speed and having reduced detection lag can be realized.
