Title: Automatic adjuster for paper sheet cutting position in rotary press machine
Inventor: NAKAGAWA HIROSHI
IPC: B26D5/34
Filed: 1986-10-13
Abstract: PURPOSE:To spread the automatic adjustment range at the cutting position by installing an adjusting roller in a passage for a paper sheet discharged from a printing machine and varying the length of the paper sheet which ranges from the printing machine to a folding machine by changing the position of the adjusting roller and cutting said paper sheet. CONSTITUTION:The standard value of the revolution phase of the rotary trunk 5 of a folding machine F for the correct cutting operation in the folding machine F is previously set in a comparison part. The actual revolution phase value of the rotary trunk 5 of the folding machine F at the time when a mark detecting means detects a mark on a paper sheet W is compared in the comparison part, and the result is sent into a control means for an adjusting roller 1. The direction of shift of the adjusting roller 1 is determined according to the result of the comparison, and the adjusting roller 1 is shifted by the portion of the absolute value of the result of the comparison. Therefore, the cutting position can be automatically adjusted over the whole range in which the adjusting roller 1 can be shifted.

Title: Rotating and retaining method
Inventor: KATO KENJI
IPC: G01D11/30
Filed: 1986-10-13
Abstract: PURPOSE:To retain a member to be rotated at an optional angle and facilitate the change of retaining angle by forming teeth-like projections on each retaining member of a rotary bearing member and the member to be rotated, and energizing the teeth-like projections to abut on each other under pressure. CONSTITUTION:To a rotary shaft 2, a member to be rotated 7 is fitted rotatably. Further, in the member to be rotated 7, projections 6c and 6d of a retaining member 6 are inserted so that the retaining member 6 is unable to rotate in relation the member to be rotated 7. When the relation between the rotational positions of a rotary bearing member 1 and the member to be rotated 7 is about to change, both retaining members 4a and 6 are going to run on each other's teeth-like projections 4d and 6b to increase a distance between both retaining members 4 and 6. Actually, a plate spring 3 inhibits it and turns the members back to the original condition of engagement. The change of relation between the rotational positions of both retaining members 4 and 6 is also inhibited by a torsion spring 5. The member to be rotated 7 is thus rotated and retained at an optional position and setting of the relation between the rotational positions is easily changed.

Abstract: PURPOSE:To eliminate the sound quality deterioration and level fluctuation and to simplify the circuit constitution by providing a digital filter converting the sampling frequency of a digital audio signal into n-time and supplying a 1st digital audio signal selectively through the filter to a D/A converter. CONSTITUTION:Digital audio signals whose sampling frequency is in the relation of a multiple are inputted selectively from an input terminal 1 and the frequency of the digital audio signal supplied via a digital filter 3 is converted twice at normal reproduction by a control circuit 8 via a signal processing circuit 2 and the result is fed to a D/A converter 5 from a switching circuit 4. In case of double speed reproduction, since the output signal of the signal processing circuit 2 is fed directly to the D/A converter 5, the frequency folded component has an equal band to two digital audio signals, an unnecessary component is eliminated by a common LPF6 and only an analog audio signal is obtained at an output terminal 7.

IPC: B60L50/16
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To maintain the energizing level of a motor as high as possible by lowering the current value supplied to an electric coil through energization instructing means when the difference between the upper limit temperature value and the detected internal temperature of an element becomes a set value or lower. SOLUTION: In order to energize electric coils 1a-1c, energization instructing means 11 and 15-17 which give energization instructing signals to a switching module IPM and a gate driver GD are provided. Firstly, the saturated temperature of an element which is reached due to the heat generated from the power loss resulting from the energization when the energization is continued is calculated. Then the internal temperature of the element is calculated by assuming that a temperature rise caused by an increase in quantity of heat occurs with a time lag after the increase occurs by using the time constant of the saturated temperature and the temperature rise caused by the heat.  On the other hand, when the difference between the upper limit temperature value and detected internal temperature of the element becomes a set value or lower, the values of currents supplied for energizing the coils 1a-1c are lowered through the energization instructing means 11 and 15-17 and gate driver GD in such a way that the current values are lowered more largely as the difference becomes smaller.

Title: Photosemiconductor element
Inventor: KOBAYASHI SHINSUKE
IPC: H01L31/10
Filed: 1983-12-26
Abstract: PURPOSE:To enable a surface electrode to keep bonding strength and prevent the deterioration of the photoelectric conversion efficiency by a method wherein the titled element has a construction that the thickness in the photo receiving region of the first conductivity type photo absorption layer close to the surface is made smaller than the thickness immediately under the surface electrode. CONSTITUTION:The surface layer 204 forms an alloy in a P type InGaAs layer 203 by sintering, having such a strength that the electrode 204 is not stripped at the time of bonding the electrode 204 to Au wires or Al wires, and the layer 203 and the electrode 204 come to ohmic contact. The photoreceiving region 205 is etched by being masked with the electrode 204, and the thickness of the layer 203 is thin 0.5mum. When a negative voltage is impressed on the electrode 204, a depletion layer is formed almost in an N type InGaAs layer 202 because the layer 203 has a higher carrier density than the layer 202. The light absorbed into the layer 203 is often recoupled in the layer 203 after photoelectric conversion into electrical signals and before being led out as the electrical signals.

Title: Method for continuously casting metal strip
Inventor: SASAKI TSUNEO
IPC: B22D11/06
Filed: 1988-09-30
Abstract: PURPOSE:To prevent longitudinal crack of a product and to obtain a metal strip having excellent quality by pouring molten metal supplied into pouring basin part or casting space while maintaining the temp. of the molten metal in the specific range. CONSTITUTION:By growing solidified shell on surface of running cooled bodies, the metal strip is continuously cast. In this case the temp. of the molten metal supplied into the pouring basin or the casting space divided with the cooled bodies is made to (t) deg.C, and the solidified point is made to T deg.C, the molten metal is poured while maintaining this in the range of the temp. of T < (t) < T + 15 deg.C. By this method, even if stress is developed, caused by shrinkage of the solidified shell precedingly developed, as there are plural starting points of the solidification, the stress is dispersed and does not become large. Therefore, the stress concentration developing to the cause of defect of the longitudinal crack, etc., is not developed.
