Title: Produciton of silicon nitride-based ceramics sintered body
Inventor: HAKOJIMA JIYUNICHIROU
IPC: C04B35/584
Filed: 1990-04-20
Abstract: PURPOSE:To reduce deformation of the ceramics sintered body by placing a molded body on a floor plate made of an Si3N4-based ceramics sintered body and introducing the molded body into a heat resistant vessel and roasting it in a N2 atmosphere of normal pressure or pressurization in a closed state. CONSTITUTION:After adding and mixing the proper amount of a sintering adjuvant selected from among MgO, Al2O3 and Y2O3, etc., and water with Si3N4 powder, the mixture is dried and the dry powder is molded into a required shape. The molded body having a volume of at least 5% for a vessel is placed on a floor plate made of an Si3N4-based ceramics sintered body and introduced into a heat resistant vessel such as a cover-fitted crucible made of carbon and covered and then inserted into a sintering furnace in a practically closed state. Thereafter the molded body is roasted for a prescribed time at 1700-1900 deg.C in the N2 atmosphere of normal pressure or at 1800-2000 deg.C in the pressurized N2 atmosphere of 0.5-10 MPa. Thereby an Si3N4-based ceramics sintered body is obtained which is little in deformation and has a high density.

Title: Side tone preventing circuit device for telephone set
Inventor: KATO NAOYUKI
IPC: H04M1/58
Filed: 1985-05-13
Abstract: PURPOSE:To prevent side tone at a telephone set when a line impedance has any value by monitoring detour toa receiver by a pseudo voice signal source and selecting the combination of plural balanced circuit networks in response to the level. CONSTITUTION:When a subscriber's telephone set 2 is connected to a telephone line 3, a test signal such as a 1kHz sinusoidal wave is sent from the pseudo voice signal source 13 and the detour level to the receiver 3 is checked by a reception level monitor 20. Then components 14-16 of the balanced circuit network 10 are selected so as to optimize the output level of the reception level monitor 20. The components 14-16 are selected not only by one combination but also plural combinations. Thus, even when a line impedance 9 has any value, the side tone of the telephone set is prevented.

Title: Manufacture of electrode film
Inventor: WAKABAYASHI HISAO
IPC: H01L41/22
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To keep the characteristic and quality of a vibrator by selecting the thickness of an outer circumferential ridge of an opening of front and rear vapor-deposition masks thinner than a plate thickness of the vapor-deposition mask to form the electrode film. SOLUTION: A vibration chip 10 is covered by a front vapor-deposition sub-mask 12 having an opening 11. Then mount parts 16, 17 are formed and the thickness of a side wall of an outer circumferential ridge 15 of the opening 11 of the front vapor-deposition sub-mask 12 is formed thin. Then a cross section 13 of the outer circumferential ridge 15 of the opening 11 of the front vapor- deposition sub-mask 12a is formed by one-side pressing after, e.g. etching so that a tilt angle is nearly 30 deg. toward the center of the opening 11. Thus, in the case of soldering the mount 16 and a support rod, intrusion due to solder is eliminated and the quality is made stable. Moreover, the shift in the frequency of the vibrator is reduced.

Title: Injection molding method for synthetic resin and its equipment
Inventor: NAKAGAWA NOBUHIKO
IPC: B29C45/70
Filed: 1985-05-15
Abstract: PURPOSE:To constitute the title method that sufficient mitigation time is taken within a mold to reduce residue of internal stress of a molded article according to cooling time of resin, by detecting the temperature and inner pressure of the resin in a cavity always respectively by a temperature and pressure sensors. CONSTITUTION:When a situation that the temperature of resin has become 135 deg.C-140 deg.C, which is close to the temperature arriving at the glass temperature Tg 600, has been detected at a cooling time of the resin, a sliding piece 6 is moved extending to an extent of several microns by actuating a pressure cylinder 8. The movement of the piece 6 is stopped when a situation that inner pressure of a mold has become the pressure presset within a range of 50-200 kg/cm<2> has been detected by a pressure sensor 4 as a result of microscopic increase of capacity of a cavity. A reason why the inner pressure of the mold has been made into the range of 50-200 kg/cm<2> is that though the pressure at a lower side is favorable when it exceeds a bar in case of paying attention to the glass temperature, as there is the possibility that a sink should be generated because of deterioration in adhesion to the mold if the pressure is too low, it has been made into necessary pressure.

Title: Laser type engine ignition device
Inventor: ENDOU HIROSHI
IPC: F02P23/04
Filed: 1980-07-30
Abstract: PURPOSE: To improve power-supply efficiency by using giant pulses generated from pulse-modulation made on a semi conduct LASER by means the energy charged in a capacitor.  
     CONSTITUTION: If an ignition command signal "a" is applied to an invertor 1141, the polarity is reversed and a transistor Q 1  is ON and OFF through a resistance R 1 . The transistor Q 1  turns from ON to OFF when the ignition command signal "a" reaches 1 level. If the transistor Q 1  is set OFF, a transistor Q 2  turns ON, and the energy charged in a capacitor 113 is supplied to the semiconductor LASER which generates giant pulses having peak-to-peak valve of approximately 20kw and pulse duration of approximately 10 microseconds. Thus, the generation of giant pulses can provide better power-wupply efficiency as compared with the use of gas LASER such as CO 2  LASER, and Solid LASER.

IPC: G11B15/43
Filed: 1994-05-18
Abstract: PURPOSE:To obtain the tension adjustment mechanism of a magnetic tape such as a video tape which can adjust tension stably without causing the tension to fluctuate even if the axis of a turnable deviates. CONSTITUTION:A tension adjustment mechanism 1 is provided with a wire 7 which is wound around the outer-periphery surface of a turnable 9 by 360 deg.Xn (n: a natural number), a tension arm 2 connected to the wire 7 by a connection member 6, and a spring 3 for energizing the tension arm 2 in the direction of an arrow A. Even if a axis 9a of the turnable 9 deviates in the directions of arrows A and B, only the position of the wire 7 wound around the outer- periphery surface moves and the base edge part of the wire 7 does not move in the directions of the arrows A and B, thus preventing the tension of the video tape 33 from fluctuating.

Title: Killer circuit
Inventor: YAMAMOTO AKIHIRO
IPC: H04B1/10
Filed: 1982-06-18
Abstract: PURPOSE:To increase a dynamic range at an output terminal, by using a signal transmitting circuit which applies an inverted Darlington connection. CONSTITUTION:A bias circuit is formed with transistors TRs 37 and 38 and resistances 31 and 33. The emitter voltage of a TR36 is fixed at the constant voltage. Therefore, a constant current flows to a resistance 30. When a signal is supplied through a terminal 1, a signal current flows to TRs 23 and 24 as well as to resistances 12 and 13. Then this signal current is sent back to a TR19 or 20 by means of an inverted Darlington circuit consisting of TRs 35-38 and resistances 30-33. If the level of a terminal 3 is lower than the reference voltage of a constant voltage source 4, the TRs 19 and 22 are turned off with TR20 and 21 turned on owing to a voltage drop of a resistance 8. Then the signal current flows to the TR20 and a resistance 15 and then is delivered through a terminal 2 via an emitter follower consisting of a TR29 and a resistance 18. When the voltage of the terminal 3 is higher than the reference voltage of the source 4, the TRs 20 and 21 are turned off with TRs 19 and 22 turned on, respectively. Then the signal current flows to the TR19 and is delivered through the terminal 2.
