Patent JP-H04356772-A (JP)
Title: Tape cassette
Inventor: TANAKA MASATO
IPC: G11B23/087
Filed: 1991-02-01
Abstract: PURPOSE:To dissolve the slack in a tape due to rolling from the exterior by positionally regulating a brake member to be oscillatable right and left at the time of hub locking. CONSTITUTION:Under the hub locking state, a guide pin 3g projected on a lower half 3 is separated from a U-shaped hole part 11g2 of a guide hole 11g. Then, when the brake member 11 is slid to a hub lock releasing position, the pin 3g is guided by a taper part 11g1 of the hole 11g to be led into the hole part 11g2. Consequently, since the member 11 is positionally regulated right and left by a hole 11f alone at the time of the hub locking, the member 11 is capable of oscillating more or less right and left with a fulcrum of a guide pin 3f. Moreover, at the time of hub lock releasing, the position is regulated right and left by the holes 11f and 11g.

Title: Method for expanding and drying food under reduced pressure
Inventor: SUGISAWA AKIRA
IPC: A23L7/10
Filed: 1983-02-25
Abstract: PURPOSE:To prepare a dry food which can be reconstituted or reconstituted and cooked to give a food having nearly the same palatability as that of the original food or the cooked original food, by rapidly evacuating a food under specific condition to effect freezing of the water in the food, and drying the product with heat. CONSTITUTION:A food is transferred from a pressurized state to an evacuated state rapidly enough to cause the expansion of the food and the freezing of water in the food. The change from the pressurized state to the evacuated state increases the degree of expansion. The food is maintained to the evacuated state until the water in the food is frozen, preferably until the lowering of the food temperature is stopped after the complete freezing, and is dried with heat by conventional heating means such as infrared heating, microwave heating, etc.

Abstract: PURPOSE:To prevent a quartz tube from deforming by regulating pressures of process gas outside a SiC port and N2 gas outside the quartz tube through regulation of the degree of opening an automatic flow rate regulating valve by means of a differential pressure sensor. CONSTITUTION:N2 outside a quartz tube 33 is discharged to the outside through a vacuum exhaust port 37b and piping 40b, while a process gas outside a SiC port 34 is discharged to the outside through a vacuum exhaust port 37a and piping 40a. In this case, a pressure difference of both air pressures is measured by a differential pressure 42. When the measured pressure difference rises above the preset value, this makes a flow rate regulating signal 42a issued from the differential pressure sensor 42.

Title: Frequency multiplying circuit
Inventor: TSUNO TOORU
IPC: H03B19/00
Filed: 1983-02-28
Abstract: PURPOSE:To improve cost performance by using a logical circuit as a pulse generating circuit, and thus realizing up to a DC area and eliminating the need for an expensive multiplying diode. CONSTITUTION:An input signal Fi is applied a Schmitt trigger circuit 5, where its waveform is shaped. A monostable multivibrator 6 is triggered by the output of the Schmitt trigger circuit 5 to generate pulses synchronizing with the input frequency signal Fi. Its pulse waveform is Fourier-transformed to calculate the N order higher harmonic output aN. Then, aN=2EdxsinNpid/Npid (where E is the amplitude of pulses), its maximum efficiency output point is pi/2, and the duty ratio (alpha) at this time is irepresented as 1/2N. Therefore, the constant of the monostable multivibrator 6 is so selected that the duty ratio (d) of output pulses is 1/2N, maximizing its output. The output signal of the monostable multivibrator 6 is applied to a band-pass filter 7 to select the Nth higher harmonic, which is amplified by an amplifier 8 and outputted as a multiplied wave NFi.

Abstract: PURPOSE:To replenish toner suitable for toner consumption by discriminating the color of a developer contained in a developing unit, changing the toner replenishment timing of a toner replenishment means according to the result and variable controlling the toner make-up amount. CONSTITUTION:The detection head part of a magnetic sensor 28 is exposed in a developing device so as to load, and the toner concentration of the developer is detected from a change in the magnetic permeability of the developer. Then an output voltage is set higher as the toner concentration becomes lower. After an A/D converter 36 A/D-converts the output voltage, it is inputted to a microcomputer 37. By combining the on and off controls of dip switches 39 and 40 in a color setting switch 38, the color of the developer is set. A power source is turned on to execute a copying action. If the output of the A/D converter 36 is below a reference value, the operation again enters a copying action. If not, a toner replenishment solenoid 41 is turned on and off according to contents set by the color setting switch 38, and toner is replenished by changing its make-up amount. Thus toner can be replenished suitable for the toner consumption.
