Inventor: TERADA SHIYOUJI
IPC: B24D3/32
Filed: 1980-01-08
Abstract: PURPOSE: To obtain a grinding wheel with high elasticity and excellent grinding capability by a construction wherein the structure of a polyvinylacetal resin grinding wheel is not made homogenous but is divided into two portions: one for grinding work and the other for the maintenance of the elasticity of the grinding wheel.  
     CONSTITUTION: For the manufacture of the grinding wheel, fine abrasive powders of fused alumina, silumdum, etc. as principal material are mixed with the suitable amount of polyvinylacetal resin or, if necessary, a compound of four different kinds of resins and then hardened to make a small aggregated lump which consists of abrasive powders and hardened resin after molding the material in the form of a stick and the like with the desired dimensions. A polyvinylalcohol solution is added to and mixed in the small aggregated lump made in the above mentioned process. After adding formalin and a small amount of acid to the lump and agitating, it is transferred to a mold for molding a grinding wheel and heat treated at about 40°C or above for several hours. This makes it possible to obtain a grinding wheel with high elasticity and excellent grinding capability.

Title: Photometric correcting device of camera
Inventor: SUDA YASUO
IPC: G03B7/28
Filed: 1984-01-07
Abstract: PURPOSE:To reduce a photometric difference between photometric modes by shifting photometric output characteristics when the stop-down metering mode and the partial metering mode are selected. CONSTITUTION:When a photographic lens is set to a cemera body in case of stop-down and partial metering mode, an aperture correcting slide resistance 45 and a bend correcting slide resistance 41 are set to resistance values corresponding to the open F value of the lens, and a brush 14b of an aperture correcting lever 14 is connected to a contact 42L, and therefore, FETs 105 and 113 are turned off together. Consequently, resistances 41 and 45 are disconnected from an operational amplifier 69. Since the input terminal of an inverter 99 is at the low level, one input terminal of an AND gate 101 is at the high level, and the output terminal of an inverter 95 is set to the high level, and an LED56 is lit. An FET103 is turned on, and a resistance 81 which corrects the gradient of output characteristics of a photometric circuit is connected to the negative input terminal of the operational amplifier 69, and the AND gate 101 is set to the high level, and a resistance 83 which shifts output characteristics in parallel is connected to the negative input terminal of the operational amplifier 69. Thus, erroneous display or degradation of the exposure precision due to switching of photometric modes is prevented.

Title: Optical phosphate glass
Inventor: YOKOE AKIRA
IPC: C03C3/19
Filed: 1981-01-08
Abstract: PURPOSE: To obtain optical phosphate glass with a large Abbe's number and high chemical durability by regulating phosphate glass contg. Al 2 O 3  in large quantities to a specified composition within the vitrifying range.  
     CONSTITUTION: This optical phosphate glass with >70 Abbe's number consists of, by wt., 70W75% P 2 O 5 , 11W15% Al 2 O 3 , 5W18% K 2 O, 0W10% B 2 O 3 , 0W3% Li 2 O, 0W8% Na 2 O, 0W8% Cs 2 O (B 2 O 3 +Li 2 O+Na 2 O+K 2 O+Cs 2 O=10W18%) and 0W5% MgO+CaO+SrO+BaO. Less than the lower limit of P 2 O 5  deteriorates the durability and increases the devitrification tendency. More than the upper limit of P 2 O 5  increases said tendency and gives high viscosity during melting, so it is difficult to obtain homogeneous glass. Al 2 O 3  improves the durability, yet less than the lower limit of Al 2 O 3  produces an insufficient effect, and more than the upper limit of Al 2 O 3  increases the devitrification tendency. B 2 O 3  stabilizes the glass and reduces the viscosity during melting. K 2 O stabilizes the glass and has the widest vitrifying range among alkalis. Li 2 O, Na 2 O and Cs 2 O stabilize the glass and reduce the viscosity during melting.

Title: Operational amplifying circuit
Inventor: TAKAGI KATSUAKI
IPC: H03F3/345
Filed: 1982-01-11
Abstract: PURPOSE:To extend the input range and to improve the common mode rejection ratio CMRR with less number of transistors (TR) and a small area, by forming a feedback circuit attached to a differential stage with DMOS constitution. CONSTITUTION:In a conventional difference stage, a bias voltage VB of a current source TR M5 is fixed to a prescribed value. In this case, when input voltages IN, IP are both high, a voltage v3 at connecting point between the M3 and M4 is also increased. Since M5 is not an ideal constant current source generally and has a differentiating resistance r5, called a drain conductance, when the current increases, output voltages v1, v2 are lowered through the presence of a differentiating resistance r1 of M1, M2. The feedback circuit comprising M6- M8, the M6 and M7 of which are of DMOS constitution, acts like to lower a bias voltage VB1 as the voltage v1, v2 are decreased, resulting that the reduction in the common mode gain Gc is decreased and the input range is extended. The CMRR is increased by the provision of a DMOS simple current source of M10, M12.

Abstract: PROBLEM TO BE SOLVED: To improve an appearance and to make a sitting person feel at ease by sliding a seat in front and back directions in the state of abutting the rear end of the seat and the lower end of a backrest at all times by an energizing mechanism. SOLUTION: By engaging a roller 7 to an optional recessed part 6b at the time of sliding the seat 2, the seat 2 is held at a position desired by a user. A torsion coil spring 12 is wound to a hinge shaft 11a, one end part of it is abutted to the back surface of an upper back plate 10a, the other end is abutted to the back surface of a lower back plate 10b and the lower back plate 10b is elastically energized clockwise. Since the lower half part 3a of the backrest 3 is elastically energized clockwise by the torsion coil spring 12, the lower half part 3a of the backrest 3 is turned to an upper half part 3b accompanying the sliding of the seat 2 in the state of being abutted to the rear end 2a of the seat 2.  Thus, even when the seat 2 is slid in the front and back directions, the lower half part 3a of the backrest 3 is abutted to the rear end 2a of the seat 2 at all times, no clearance is present between the rear end 2a of the seat 2 and the lower half part 3a of the backrest 3 and the appearance of this entire chair is substantially improved.

Abstract: PROBLEM TO BE SOLVED: To minimize a parasitic capacity caused by overlap for controlling a short channel effect by providing an embedded gate electrode in a semiconductor substrate which is formed in self-conformity manner to the opening of an interlayer insulating film for a gate electrode, which is to be an electrode connected electrically to the gate electrode. SOLUTION: With a channel region sandwiched therebetween, from above and below, a gate electrode 25a and an embedded gate electrode 22a, an electric potential applied to the embedded gate electrode 22a suppresses the effect of a drain electric potential to the channel region, improving a short channel effect. Since the embedded gate electrode 22a is formed by implanting an impurity ion from an opening part 20a where the gate electrode 25a is formed, the gate electrode 25a is formed in self conformity. These gate electrodes 25a are automatically aligned so superposing tolerance is minimized, thereby minimizing a parasitic capacity.

Title: Voice packet string reception and reproduction system
Inventor: NUNOKAWA MASAKATSU
IPC: H04L49/9023
Filed: 1989-01-09
Abstract: PURPOSE:To avoid the abort of a packet or increase in the delay time of the packet by expanding or contracting a reproduction time of a silence packet received preceedingly properly in response to the interval of voiced packets when two voiced packets or over are received continuously in succession to the reception of the silence packet. CONSTITUTION:Only voiced packets d1, d3, d4 are sent to a packet network in a prescribed transmission timing. The sent head packet d1 is received by the receiver side as a packet e1 in a transmission delay time t0 and the succeeding packet d3 is received in a fluctuated delay time. The time interval of the voiced packets reaching the reception buffer is measured sequentially at the reception of each packet and the statistic value is obtained to reproduce the received packet. The time interval ta between the packets to be reproduced at present is compared with statistic value and when the statistic value is smaller, the reduction processing is applied with respect to the reproduction time of the silence packet and when the statistic value is larger, expansion processing is applied. Thus, the entire packet delay is reduced and the abort of packet is avoided.
