Title: Air box structure for automobile
Inventor: TANUMA KINICHI
IPC: B60H1/28
Filed: 1990-01-22
Abstract: PURPOSE:To reliably prevent entrance of rainwater to an outside air introduction port by feeding air to the outside air introduction port through the ventilating port of a partition wall member being an air passage, meanwhile dropping rainwater to a position right before the partition wall member to drain rainwater through a communicating opening through a drain passage. CONSTITUTION:During normal running of a vehicle, outside air flows in an air box 21 through an opening part 22b of an upper surface 22a of a cowl top panel 22. After the outside air flows to the inner side of a partition wall member 24 through a ventilating port 24c of a side wall 24e, the outside air is introduced through the outside air introduction port 23b to an air conditioner. Meanwhile, during running on a rainy day, rainwater flows in the air box 21 together with the outside air. However, rainwater drops on a bottom part 23a and after it flows through a drain passage 23d to a side panel 25 side, it is drained through a communicating opening 26 to the outside. Namely, since air passages 24c and 23b are completely separated away from the drain passage 23d by means of the partition wall member 24, entrance of rainwater to the outside air introduction port 23b is reliably prevented.

Title: Data transfer system
Inventor: HITOMI AKIRA
IPC: G06F13/42
Filed: 1980-02-06
Abstract: PURPOSE:To elevate utilization efficiency of the system bus, by making the system bus vacant at all times a every 1 byte, even when a data is transferred between two passive equipments. CONSTITUTION:When the data transfer module DMA1 is not operated, the DMA request receiving signal inversion DACK4 is in a high level. On the other hand, the signal 4 is inverted through the inverse circuit 6 and becomes a low level. Since this low level signal is made DMA request signal inversion DRQ3, it is regarded as a transfer request of the DMA1. Subsequently, when the DMA1 is made enabling, the DMA1 samples the signal 3 of a low level and starts the operation. When the DMA1 has occupied the system, the signal 4 of a low level is output and the signal  3 becomes a high level, therefore the data transfer request is stopped. The DMA1  samples the signal 3 of a high level, finishes a data transfer of once, and releases  the system bus by 1 byte period. In this way, the transfer is executed, making the system bus vacant at every 1 byte.

Title: Universal joint
Inventor: KOBAYASHI KATSUYUKI
IPC: F16D3/20
Filed: 1988-01-25
Abstract: PURPOSE:To simplify the structure and reduce the cost by arranging a rolling body so as to be in contact with a first engagement part of an inner part and a second engagement part of an outer part, and forming one of the contact faces to be a concave while the other a flat face. CONSTITUTION:When a universal joint 10 rotates forming a joint angle, a rolling body 16 rolls on a flat face 29, and a relative movement generates between the rolling body 16 and a first, or a second engagement part 13a, or 15a in both axial and radial directions. Friction resistance in the relative movement is remarkably reduced accordingly, and equal velocity rotation is performed according to the same equal velocity principle as a conventional equal velocity joint. Since the construction is such that the rolling body 16 is held in a specified position by means of a concave 22 formed on the first engagement part 13a of an inner part 12, and turned on the flat face 29 formed on an outer part 14, number of parts is remarkably reduced compared with a conventional one and the structure is simplified. Cost is therefore reduced.

Title: Color thermal printer
Inventor: TERANISHI YUKIHIDE
IPC: B41J2/325
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To increase the printing speed by an arrangement wherein a dimmer circuit varies the emission luminance of a fixing lamp at the time of reverse feeding a color thermal recording material based on the operation results of an operating circuit thus obviating the need for preliminary lighting of fixing lamp. SOLUTION: Light emitted from a magenta fixing lamp or an yellow fixing lamp 6 is detected by a photosensor 8 while delivers a detection signal to an illuminance detection circuit 9 where the illuminance is detected. Illuminance information from the illuminance detection circuit 9 is operated at an operating circuit 10 and delivered to a dimmer circuit 11 which then delivers a pulse width modulation signal through an inverter 12 to the magenta fixing lamp and yellow fixing lamp 6 thus dimming them. Upon finishing the fixing with the yellow fixing lamp 6, recording and fixing of magenta is performed similarly followed by recording and fixing of cyan thus completing the printing.

Title: Ink jet printer
Inventor: HASHIMOTO TAMAKI
IPC: B41J2/175
Filed: 1990-01-24
Abstract: PURPOSE:To make it possible to dispense with the arrangement of a special detection device and detect or inform a residual amount of ink without any cost increase by detecting the residual amount of ink in accordance with the response variations of a controlled object. CONSTITUTION:If there is ink in an ink tank 30 on a carriage 6 or in a jet head on the carriage 6, the mass of the carriage is larger than when it is not filled with ink. In addition, the gravitational center moves when the speed of the carriage is accelerated. Subsequently, if the same PWM value is given, the accelerated speed is lower than when the carriage is not filled with ink, resulting in the low response rate of a controlled object. Therefore, when the actual carriage speed is higher than a target speed, the presence of ink of the low-level residual amount of ink can be detected by comparing a value stored previously in ROM, that is, an estimated minimum PWM duty with a calculated PWM value. If the detection is made, 'no ink' flag provided in RAM is set to be ON. If the flag is ON, 'no residual ink' display lamp on a control panel 160 is turned ON to prompt a replacement of an ink tank 30.

Dephosphorization reaction is thus accelerated to obtain a low-phosphorus steel. Oxygen blowing is suspended in the midway of blowing if necessary and the slag contg. the phosphorus oxide is discharged to the outside of the furnace, then again the furnace is erected. An auxiliary raw material of CaO and the above- mentioned oxygen-contg. solid material are added to the furnace inside to manufacture slag having high oxygen potential in the end period of blowing. The blowing is continued to accelerate the dephosphorization reaction. The amt. of the phosphorus in the molten steel is further reduced by the above-mentioned method.

Abstract: PURPOSE:To enable ideal shoulder making and to grow a single crystal having high quality by specifying the upper limit value of an mV set value according to the pulling up length of the single crystal in a Czochralski method. CONSTITUTION:The weight of the single crystal under growth is detected by using a high-frequency heating furnace attached with an analog controller which has a vacuum thermocouple in a high-frequency coil and controls the supply electric power of a high-frequency oscillator so as to approximate the electromotive force of the vacuum thermocouple to the mV set value (M1) and the diameter of the crystal is controlled by changing the M1 in such a manner that the increasing speed thereof changes in compliance with the previously determined program. The upper limit value of the change quantity V0 of the M1 is set at V0=30-50muV/hour when 0<l<=l1 (0-45mm), V0=20-30muV/hour when l1<l<=l2 (45-75mm), V0=15-25muV/hour at l2<l<=l3 (75-110mm), and V0=5-20muV/hour when l3<l (where l1, l2, l3 are the lengths of the crystal under growth). The diameter control is thereby enabled with good reproducibility and the high-quality single crystal is grown.
