Title: Circuit designing device and method therefor
Inventor: KITANO HIROAKI
IPC: G06N3/00
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To design a large scale logic circuit. SOLUTION: Based on genetic algorithm, the circuit constitution of a programmable logic circuit (PLD) is updated and the logic circuit for performing object output is designed. Corresponding to the genetic algorithm, the set of grammatical rules (for instance, (a) to (d)) for leading out the circuit constitution of the PLD is turned to a chromosome, the chromosome (the set of the grammatical rules) is updated and the chromosome for supplying optimum circuit constitution is led out. At the time, since the length of the chromosome is proportional to the number of the grammatical rules, without depending on the scale of the circuit of the PLD, the circuit constitution is designed in appropriate calculation time even when the circuit of the PLD is a large scale.

Title: Optical modulator
Inventor: AJISAWA AKIRA
IPC: G02F1/025
Filed: 1989-09-11
Abstract: PURPOSE:To obtain the optical modulator of 1.5mum band wavelength which operates on a low voltage by using a strained superlattice structure for a multiple quantum well (MQW) guide layer. CONSTITUTION:The lattice constant of InGaAs is smaller than the lattice constant of InP and lattice mismatching arises. The compsn. ratio of In in the InAlAs which is a barrier layer is increased and the lattice constant is so set as to be made larger than the lattice constant of InP to insert strains in respectively opposite directions between the well layer 8 and the barrier layer 9 by which the growth to the InP substrate 1 is allowed in the case of the MQW. An arbitrary exciton peak wavelength at an arbitrary well thickness is set by controlling the compsn. of the In of InGaAs and InAlAs if the strained superlattice structure of InGaAs/InAlAs is used. The optical modulator which operates on the sufficiently low voltage even at 1.55mum band is obtd. in this way.

Through the opening parts 9, air flow is secured in the region near the inner surface of the lens 2 and generation of cloudiness due to dew condensation on the inner surface of the lens 2 is prevented. Especially in a lower hem region of the lens 2 and in regions on both the left and right side of the lower hem of the lens where cloud is easily generated, and cloudiness is prevented effectively.

Title: Rotary magnetic head device
Inventor: KAWAI TSUTOMU
IPC: G11B15/61
Filed: 1989-09-14
Abstract: PURPOSE:To eliminate interference between a tape and a lead part and to reduce damage for the tape by providing the escape part of the lead part in a contact part between a lower drum and the tape in the tape exit part of the lower drum and removing pressing force caused by a guide post. CONSTITUTION:A lead part 1a of a tape T is fed to a lower drum 1 and the tape T is slightly pushed downward by a guide post 4 with flange for tape height adjustment. The interference between the tape T and the lead part 1a is eliminated by an escape part 1ax of the lead part 1a. Since there is no regulation for a tape breadthwise direction in a part where tape tension is large, tape traveling load is reduced and vibration in the breadthwise direction caused by tape edge slit is reduced. Then, the damage for the tape is reduced even when the tape is traveled at high speed. Further, by improving the working condition of the lead part, accuracy for linearity, etc., is improved.

Filed: 1987-09-24
Abstract: PURPOSE:To reduce the personnel expenses, and also, to prevent a work miss at the time of switching work by switching an erroneous erasion preventing expression switching means in accordance with an instruction from a switching control means. CONSTITUTION:When an instruction to protect the storage is received from a host controller 7 after a storage work, an information storage device 3 starts a work for switching a state of an erroneous erasion preventing expression mechanism 2 to an erroneous erasion preventing state from a recordable state by using an erroneous erasion preventing expression switching means 4 through a switching control means 5. When the switching control means 5 recognizes a fact that said state has become the erroneous erasion preventing expression switching means 4. As a result, the information storage medium 3 stored with information is inhibited from storing the information. In such a way, the personnel expenses for a switching work to the erroneous erasion preventing state are reduced, and also, a work miss such as forgetting to execute its work or executing a miss can be prevented.

Title: Image forming device
Inventor: IBUCHI YOSHIAKI
IPC: G03C8/50
Filed: 1988-09-21
Abstract: PURPOSE:To prevent a rapid increase in burden imposed on a pressure roller and the defective engagement of a photosensitive, pressure-sensitive material into the pressure roller by decelerating the speed of the pressure roller or releasing pressure when the leading edge of the material passes through the pressure roller. CONSTITUTION:When a sensor MS2 provided ahead of the pressure roller 2 detects a picture receiving sheet, a timer (t) starts. Simultaneously, a pressure releasing motor 24c normally rotates to lift a holder 21b, and the pressure of the pressure roller 2 is released. As a result, the engagement of the picture receiving sheet into the pressure roller is facilitated. The rotational speed of the pressure roller 2 is set lower (speed V2) after time T1 elapses since the sensor MS2 is turned on. When the engagement of the leading edge of the picture receiving sheet into the pressure roller starts, its rotational speed slows down to release the burden of the pressure roller when the sheet is engaged. Consequently, the engagement into the pressure roller 2 slows down to eliminate rapid increase in the burden imposed on the pressure roller 2.
