Title: Laser ray projection device
Inventor: SUZUKI NORIYUKI
IPC: G02B27/28
Filed: 1988-10-12
Abstract: PURPOSE:To reduce the formal distortion of laser rays by half by a method wherein a liquid crystal shutter composed of a single light polarizing plate is provided. CONSTITUTION:Laser rays 21 emitted from a laser ray source 20 are processed into laser rays 25 of a specified shape through a liquid crystal shutter composed of a liquid crystal display element 22 and a light polarizing plate 23, which are projected onto a target plane. In this case, the laser rays 21 are not required to align their polarized light ray front with a polarizing plate as they have been collimated and polarized already, so that they are screened by the liquid crystal shutter 24 composed of only a single polarizing plate 25. By this setup, the laser rays 25 restrained from being distorted in form can be obtained.

Title: Magnetron drive circuit
Inventor: NAKAI SATOSHI
IPC: H05B6/68
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary radiation at the operation starting time by connecting a switching element in series between a capacitor of a half-wave voltage doubler rectifier circuit and a cathode of a magnetron. SOLUTION: A cathode 2a of a magnetron 2 is connected between a capacitor 3 and a diode 4 which are connected to the secondary terminal side of a high voltage power source transformer 1b and constitute a half-wave voltage doubler rectifier circuit. Output of the magnetron 2 is adjusted by ON-OFF time of a switching element 7 connected in series between the capacitor 3 and a cathode 2a. Even if the element 7 is turned off just after the operation is started, since voltage is always supplied to the cathode 2a, time till a normally oscillating temperature is shortened, and the time easily generating unnecessary radiation is shortened. Since an electric current is always carried to the cathode 2a even at the output adjusting time, unstable oscillation at the transient time to ON from OFF is eliminated.  Preferably, the element 7 is turned on after a necessary time up to becoming a cathode temperature at which the magnetron 2 normally oscillates at the operation start time.

Title: Cooking plate
Inventor: AKAMATSU TOMOHIKO
IPC: A47J27/00
Filed: 1989-10-02
Abstract: PURPOSE:To improve the hear transfer efficiency to the inside of a material to be cooked and to improve the way to handle by forming at least the surface layer on the side in contact with the material to be cooked of a titanium alloy and providing a porous part and/or plural recessea on the surface made of the titanium alloy. CONSTITUTION:This cooking plate 1 is made of the titanium alloy (6Al-4V-Ti) contg. aluminum and vanadium and is produced (sintered) by a powder metallurgical method. The heat transfer is effected not only from the surface layer of the porous plate body 5 made of the titanium alloy in the part direct contact with the material to be cooked but also via the convection of the heated air in respective microholes 5. The temp. fall over the entire part of the cooking plate 1 when the material to be cooked is placed thereon is suppressed by the low thermal conductivity of the titanium alloy bottom 2 itself of the cooking plate 1 and the air itself in the microholes and further by the decreased contact area (70%) of the porous plate body 5 with the material to be cooked. As a result, the continuous heating of the material to be cooked placed on the cooking plate 1 at a nearly uniform temp. is possible and, therefore, the rapid heating of only the surface of the material is obviated and the heat is adequately transferred even to the inside of the material to be cooked.

Abstract: PURPOSE:To prevent a line width ratio between a longitudinal line and a lateral line changing and print quality deteriorating corresponding to the change of the driving power of a light source by setting a time to increase a driving current with a first delay circuit, and setting a time to adjust a beam diameter with a second delay circuit independently, respectively. CONSTITUTION:A VIDEO signal is inputted to delay circuits 44, 45 respectively. The delay circuit 44 is provided with delay time DEL1 (duty value), and the delay circuit 45 is provided with delay time DEL2 (overshoot time). Since the VIDEO signal and the output of the delay circuit 44 are inputted to an OR circuit 46, a VDEO signal longer by the delay time DEL1 is outputted to the VIDEO signal. Meanwhile, the delay output of the delay circuit 45 is inverted with an inversion circuit 51, and is inputted to the input terminal on one side of an AND circuit 52. Since the VIDEO signal is inputted to the input terminal on the other side of the AND circuit 52, an HVDEO signal is outputted during the delay time DEL2 from the rise of the VIDEO signal.

CONSTITUTION:When a primary winding 5 (low-voltage side) of a transformer 4 for impressing a high voltage to which a test sample (capacitance) 7 is connected is excited 3 with a direct current and a transistor TR11 is interrupted suddenly, the high voltage is generated in a secondary winding 6 (high-voltage side) by the energy stored in the transformer 4. When a transistor TR2 is put in continuity after an arbitrary time passes from extinction of a waveform of positive polarity generated by the transistor TR1, the transformer 4 is excited with the direct current in the reverse direction and a waveform of the reverse polarity being symmetrical is generated in the secondary winding 6. By impressing interval waves of the two polarities generated in this way and an alternating-current voltage on the sample 7, an effect produced on an insulation performance of a cable line, partial discharge behavior thereof in particular, can be examined and a test of high reliability can be executed.
