Title: Master production of optical disk
Inventor: OYAMA MINORU
IPC: G11B7/24079
Filed: 1994-04-27
Abstract: PURPOSE:To simplify a control system and mechanism and to prevent appearance of wobbling on the side walls on a non-wobbling side by adopting a light intensity modulation system in a process for producing a master of an optical disk subjected to wobbling only on the one side wall of grooves. CONSTITUTION:This master is constituted in the form of partly superposing two pieces of condensed light spots Sa, Sb on a photoresist 17a of a glass master disk 17 by using two pieces of light beams A, B. Wobbling formation is executed by modulating the light intensity of the one beam B with an AOM (acoustooptical modulator) 16. The other beam A is subjected to light intensity modulation of small amplitude in an anti-phase relation from the phase described above by an AOM 21. The crosstalk components of the beam B are cancelled and the photosensitization including the wobbling components on the non- wobbling side is prevented.

Title: Method of ion implantation
Inventor: NISHIYAMA KAZUO
IPC: H01L21/331
Filed: 1989-04-28
Abstract: PURPOSE:To enable implanting ions with high concentration deep into a narrow region by implanting the ions at an incidence angle of 0 deg. to the same position with different kinds of implantation energy. CONSTITUTION:When high-energy ions are implanted selectively into a semiconductor, the ion implantations (a)-(d) are performed at an incidence angle of 0 deg. with different kinds of implantation energy having different peak positions. In this time, the sum of the concentration profiles of the types 21-24 of distribution provides uniform high-concentration distribution in the direction of the depth and the ion implantations to the same position sufficiently prevent the implanted ions form spreading horizontally. Thereby a narrow and deep plug-in region 14 is formed.

Title: Gate drive unit and power module
Inventor: TAKANASHI TAKESHI
IPC: H02M1/08
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To shorten the unstable period of operation in turning off. SOLUTION: A dividing resistive element 2 is inserted between terminals 22, 23 and the connecting part of a first and a second resistive elements 2a, 2b is connected to one input of a logical circuit (NOR) 3. Therefore, in turning off, the logical circuit 3 outputs a high level signal when the gate voltage Vg is reduced exceeding the value near the threshold voltage of a power switching element 1 higher than the input threshold of the logical circuit 3. As a result, the power switching element 1 shifts to the stable cut-off state. Namely, though the threshold of the power switching element 1 is higher than the threshold of the logical circuit 3, the stable cut-off state can be quickly realized.

Title: Print start control device for copying machine
Inventor: AISAKA SEIYA
IPC: G03G15/00
Filed: 1985-05-22
Abstract: PURPOSE:To remove the complexity of reinput and to restart copying automatically by outputting a copy continuing signal when a copy enable state and a state on the way of copying are detected at the time of jam processing. CONSTITUTION:At the time of jam processing, no jam is detected by paper blocking detecting switches 24-26 of a jam detecting means 29. When a safety cover is closed after the jam processing, the completion of post processing is detected by a safety switch 45 of a post processing detecting means 30. When the temperature of a fixing device or the like is discriminated as a copy enable state by a state discriminating means 31 and the set number of copies is still left and the state on the way of copying is discriminated by an operation discriminating means 36, a copy continuing signal is outputted from a control means 35. Consequently, it is unnecessary to reinput the set number of copies or the like and copying can be automatically restarted.

Title: Voltage generating circuit
Inventor: YAMAMOTO AKIHIRO
IPC: G11C11/407
Filed: 1987-05-07
Abstract: PURPOSE:To reduce the fluctuation of a production process and also to decrease the power consumption by adding a MOS transistor (TR) to absorb said production process. CONSTITUTION:The threshold voltage of a MOSTRQ1 is changed by DELTAVth owing to the fluctuation of a production process, etc., and at the same time both MOSTRs Q3 and Q4 also have the fluctuation of their threshold voltage values by DELTAVth. Thus the potential of a connection point A is also varied by DELTAVth and therefore the potential of an output terminal O is always constant. Furthermore the point A is charged in a short time through a resistance R11 when a power supply is applied since the capacity obtained at the point A is sufficiently small compared with the capacity of a load capacitor CL. Then the capacitor CL is also charged quickly via the TRQ1. In addition, the power consumption is limited to only a small current that flows via resistances R11 and R12 since the TRQ1 is cut off after the capacitor CL is charged by the VDD/2 voltage value.

IPC: H01Q3/04
Filed: 1986-05-15
Abstract: PURPOSE:To obtain an elevating angle adjusting mechanism where an operating torque of a handle for the elevating angle is reduced and the processing is facilitated by devising the mechanism that a rotary shaft is swung around a tilted member fitted to a horizontal base within the vertical plane including the shaft center of a reflector antenna. CONSTITUTION:In turning the elevating angle handle 8 to the right, the rotary shaft 10 is driven to the right, a screw 11 is projected from the lower side of the tilt member 40 and the rear part of a horizontal member 2B of a bearing 30 goes down. Since the front part of the horizontal member 2B is supported to the shaft 4, the horizontal member 2B is tilted downward in the rear direction around the shaft 4 by an angle alpha, and the reflector antenna is tilted upward. The lower part of the rotary shaft 10 is held around the tilted member 40 and a bearing 30 at the head is swung around a half shaft 33B, then the rotary shaft 10 is tilted inward by an angle beta within the vertical plane including the axial center of the reflector antenna. Thus, no side pressure is exerted to the shaft 10 and only an axial torque is given to a screw hole 40B and a thread of the screw 11, the elevating angle is adjusted without increasing the torque of the handle 8.

Title: Preventing method for roll slip of rolling mill
Inventor: SAKAMOTO GUNJI
IPC: B21B1/22
Filed: 1985-05-24
Abstract: PURPOSE:To prevent the slip of rolls between rolling rolls and rolling material by measuring the torque of the rolling rolls to detect a lubricating condition and controlling the flow of a rolling mill lubricant so as to make uniform the lubrication. CONSTITUTION:The upper and lower work rolls 12A, 12B are separately driven by driving motors 16A, 16B. Driving currents 1A, 1B are detected by shunts 24A, 24B. Both currents are calculated in a comparator 26 and a torque difference TC of the upper and lower rolls is determined. The flow signals V1, V2 of the rolling mill lubricant at which the roll lubrication is made uniform is determined from the signal of the above-mentioned torque difference TC by the empirically patterned calculation in a rolling mill lubricant flow calculator 28. Said signals are outputted to control valves 30A, 30B which spray the lubricant at said flow rates. The roll slip is therefore prevented and the breakdown of the rolling material by the slip is prevented.
